海外TECH	DEV Community	Exploring the NoSQL Powerhouse Amazon DynamoDB	https://dev.to/brandondamue/exploring-the-nosql-powerhouse-amazon-dynamodb-394b	Exploring the NoSQL Powerhouse Amazon DynamoDBIn the ever evolving world of cloud based databases Amazon DynamoDB emerges as a bona fide powerhouse DynamoDB is designed to handle massive workloads serving as a foundation for modern applications that demand seamless low latency access to vast amounts of data With its unique combination of speed reliability and seamless integration with the AWS ecosystem DynamoDB empowers developers to build reliable and scalable cloud solutions In a previous article check it out here I examined the major database offerings provided by AWS giving a brief overview and example use case of each However I am shifting my focus in this article to examining the pool of features DynamoDB offers By the time we get to the end of the article I am hoping to have made it clear to you why DynamoDB is considered a powerhouse in the committee of cloud based databases We will start by having a high level overview of DynamoDB and then move on to exploring its features That being said let s get right to it OverviewDynamoDB a fully managed key value NoSQL database service in the AWS ecosystem is designed to provide fast scalable and highly available storage for applications needing low latency access to structured and semi structured data By eliminating manual capacity planning and infrastructure management DynamoDB simplifies database administration allowing developers to focus on building applications while benefiting from automatic scaling high availability and durability Its flexible data model accommodates various data types and its seamless integration with other AWS services enables developers to create powerful interconnected solutions With DynamoDB s scalable architecture businesses can handle unpredictable workloads ensuring consistent performance and freeing up resources for innovation and growth DynamoDB s data model embodies remarkable flexibility and a schema less nature providing developers with a powerful tool for storing and retrieving data in a highly adaptable manner DynamoDB Tables serve as containers for related information while items represent individual records or entities within those tables One of the key strengths of DynamoDB lies in its support for both key value and document oriented data models offering advantages in different scenarios The key value model allows for efficient data retrieval using a primary key ideal for quick access to specific items In contrast the document oriented model provides greater flexibility by enabling the storage of nested and complex data structures within items making it ideal for semi structured or evolving data This flexibility extends to the accommodating of various data types where each attribute within an item can have a different data type allowing developers to handle diverse data requirements seamlessly Moreover DynamoDB s schema less nature facilitates effortless schema evolution enabling the addition of new attributes without modifying existing data and adapting to changing business needs with ease With this overview of DynamoDB out of the way let s move on to talking about its core features and concepts Read amp Write Capacity Unit RCU amp WCU Read and write capacities are crucial concepts that directly impact the performance and cost of DynamoDB They determine the throughput or the number of read and write operations that can be performed per second on a table or index Write Capacity Units WCUs represent the capacity for write operations One WCU allows you to write one item per second with each item being up to KB in size You can provision WCUs based on your application s anticipated write traffic If your application needs to handle higher write throughput or larger items you can adjust the number of WCUs allocated DynamoDB manages the distribution of the write workload across partitions to maintain data consistency and durability Read Capacity Units RCUs represent the capacity for read operations One RCU allows you to read one item per second with each item being up to KB in size This is for strongly consistent read operations For eventually consistent reads RCU allows you to read one item of KB per second and for DynamoDB Transactions RCU allows you to read one item of KB per second You can allocate RCUs to a table to handle the expected read traffic If your application requires higher read throughput or the retrieval of larger items you can increase the number of RCUs allocated DynamoDB automatically distributes the read workload evenly across the table s partitions ensuring efficient access to the data The relationship between read and write capacities and DynamoDB s performance is straightforward By provisioning higher RCUs and WCUs you increase the overall throughput capacity allowing your application to handle more read and write requests per second This results in improved performance faster data retrieval and reduced latency However it s important to note that excessive provisioning of capacities can lead to unnecessary costs so it s essential to strike a balance based on your application s needs Strongly Consistent vs Eventually Consistent ReadsIn DynamoDB read operations offer two consistency models strongly consistent reads and eventually consistent reads Strongly consistent reads provide the most recent copy of data reflecting all successful write operations prior to the read This ensures immediate and up to date data consistency making it suitable for critical scenarios like financial transactions or real time inventory management However strongly consistent reads may have a slight impact on performance On the other hand eventually consistent reads prioritize higher read performance by returning slightly stale data that reflects updates made in the recent past While not offering immediate consistency eventually consistent reads are well suited for scenarios such as analytics or caching where slightly outdated data is acceptable and higher throughput is desired It s worth noting that the choice between strongly consistent and eventually consistent reads can be made at the individual read operation level allowing you to tailor the consistency model based on your specific needs DynamoDB provides the flexibility to strike a balance between data accuracy and performance by choosing the appropriate consistency mode for each read request By understanding the differences and trade offs between strongly consistent and eventually consistent reads you can optimize your application s performance and ensure the desired level of data consistency based on the requirements of different use cases DynamoDB Indexing Primary Keys LSI amp GSI DynamoDB provides several indexing options to enhance data access patterns and query flexibility The first indexing option is through primary keys which consist of partition keys and composite keys Partition keys determine the partition in which items are stored while composite keys combine the partition key hash key and sort key range key for efficient querying within a specific partition By carefully selecting primary keys you can optimize data distribution and enable efficient retrieval of items based on specific criteria In addition to primary keys DynamoDB offers local secondary indexes LSIs LSIs share the same partition key as the original table but have a different sort key They allow for querying data within a specific partition and enable optimization of read operations by retrieving a specific range of items within that partition LSIs are particularly useful when you need to access and query data using different sort keys while maintaining efficient partition level access DynamoDB also provides global secondary indexes GSIs which are independent indexes with their own partition and sort keys GSIs offer the flexibility to query items across different partitions using alternative keys With GSIs you can perform non key attribute queries and access patterns that are not efficiently supported by the primary key or LSIs They allow for diverse and targeted queries on your DynamoDB table extending the range of access patterns and enhancing query performance By taking advantage of the indexing options provided by DynamoDB you can optimize data retrieval and query These indexes enable efficient access to specific partitions facilitate range queries within partitions and broaden the scope of query patterns beyond the primary key Careful consideration of your data model access patterns and performance requirements will guide you in selecting and utilizing the appropriate indexing options ultimately enhancing the performance and flexibility of your DynamoDB queries Data Consistency and AtomicityIn a previous section I briefly talked about read consistency in DynamoDB Now let s talk about how Dynamo ensures atomicity in read and write operations within a single item It ensures atomicity by making use of Conditional Writes where write operations are executed atomically based on specified conditions preventing data inconsistencies In addition DynamoDB supports distributed transactions through DynamoDB Transactions allowing multiple read and write operations to be grouped as a single all or nothing unit of work guaranteeing ACID properties across multiple items or tables By leveraging Conditional Writes and DynamoDB Transactions developers can maintain data integrity handle complex operations and ensure consistency and reliability in their applications using DynamoDB s scalable and performant database service Performance OptimizationDynamoDB s elegant performance is one of the key features that place it high up in the scheme of cloud databases With this in mind let s see some of the techniques DynamoDB leverages for performance optimization DynamoDB offers a range of performance optimization techniques to improve the efficiency and scalability of database operations One such technique is batch operations which allow multiple read or write operations to be grouped together minimizing network round trips and improving overall efficiency By bundling related operations into a single request batch operations significantly reduce network latency and increase throughput They are particularly beneficial for scenarios involving bulk writes or retrieving multiple items simultaneously as they help streamline data access and processing Additionally DynamoDB provides parallel scans and parallel queries to enhance performance Parallel scans divide a large table scan into smaller segments that can be scanned concurrently leveraging parallelism to expedite data retrieval This technique is especially useful when dealing with large datasets or time sensitive scan operations Similarly parallel queries break down a query into smaller segments that can be executed in parallel enabling faster data retrieval by scanning multiple partitions concurrently These techniques can effectively minimize query latency and improve overall query performance To further optimize performance it is crucial to consider factors such as data modelling partitioning strategies and efficient index usage Designing efficient primary keys leveraging appropriate local and global secondary indexes and evenly distributing database workload across partitions are essential steps for achieving high performance and scalability Features like adaptive capacity and DynamoDB Accelerator DAX can also be leveraged to automatically scale capacity and cache frequently accessed data respectively to further enhance performance Integration with other AWS servicesDynamoDB integrates seamlessly with various AWS services expanding its capabilities and allowing for powerful data processing and analysis Integration with AWS Lambda enables you to trigger serverless functions in response to DynamoDB events facilitating real time data transformations validations or custom business logic By leveraging DynamoDB Streams you can capture and send data modification events to Amazon S enabling data backups analytics and offline processing Additionally the integration with Amazon Kinesis empowers you to process and analyze streaming data from DynamoDB in real time building robust data processing pipelines By utilizing the AWS Database Migration Service DMS DynamoDB can seamlessly integrate with Amazon Redshift facilitating easy data migration for analysis reporting and data warehousing purposes These integrations enhance its capabilities allowing developers to leverage a broader suite of AWS services for various data processing and analytical needs thereby driving more value from their applications Security amp Monitoring in DynamoDBDynamoDB offers robust security features to protect data both at rest and in transit Encryption at rest implemented through AWS Key Management Service KMS ensures that data stored on disk is encrypted providing an additional layer of protection Encryption in transit achieved through Transport Layer Security TLS protocols safeguards data as it travels between client applications and DynamoDB preventing unauthorized interception or tampering By employing encryption at rest and in transit DynamoDB ensures the confidentiality and integrity of data throughout its lifecycle In terms of access control DynamoDB integrates seamlessly with AWS Identity and Access Management IAM allowing fine grained control over user permissions IAM enables you to define and manage access policies granting or restricting access to specific DynamoDB tables APIs or operations By implementing least privilege principles you can ensure that only authorized users or applications have the necessary privileges to interact with DynamoDB resources reducing the risk of unauthorized access and data breaches DynamoDB integrates with CloudTrail to provide auditing capabilities CloudTrail captures detailed information about API calls made to DynamoDB including the user who made the request the timestamp and the outcome This allows for tracking and monitoring of changes aiding in security analysis compliance adherence and troubleshooting activities By leveraging these security features of DynamoDB organizations can safeguard their data maintain control over access permissions and gain visibility into DynamoDB API activity reinforcing the overall security posture of their applications For performance monitoring DynamoDB leverages robust monitoring options such as CloudWatch metrics and alarms CloudWatch metrics offer valuable insights into the performance of DynamoDB tables by capturing data such as read and write operations consumed capacity units throttling and latency These metrics allow you to track usage patterns identify potential bottlenecks and monitor the health of your DynamoDB environment By setting up CloudWatch alarms you can proactively detect and respond to critical changes in DynamoDB metrics triggering notifications or automated actions when predefined thresholds are breached Together these monitoring options enable you to optimize performance ensure high availability and deliver a seamless user experience with your DynamoDB tables Final thoughtsI have covered most of the major features of DynamoDB My objective was to make it clear to you why DynamoDB is considered a powerhouse in the world of cloud based databases Its flexible data model robust security features and integration capabilities with other AWS services make it a compelling choice for modern application development Regardless of the type of solution you are building DynamoDB provides the reliability scalability and performance needed to meet the demands of your use case Share your thoughts about DynamoDB and other cloud related topics with me in the comments

海外TECH	DEV Community	Tudo que você precisa saber sobre Terraform	https://dev.to/1cadumagalhaes/tudo-que-voce-precisa-saber-sobre-terraform-3bp4	Tudo que vocêprecisa saber sobre TerraformTerraform éuma ferramenta open source desenvolvida para facilitar a criação gerenciamento e a automatização da infraestrutura como código que vamos chamar de IAC da sigla infra as code Sua principal vantagem éque vocêescreve a sua infraestrutura de forma declarativa e a ferramenta fica responsável por implementar seus recursos de maneira consistente A grande maioria de exemplos de utilização de terraform pela internet écom AWS Como trabalho com Google Cloud vou fazer os exemplos baseados nisso Tudo que eu preciso saber sobre Meu objetivo aqui ésimples prover toda informação disponível para você pessoa desenvolvedora começar e conseguir usar a ferramenta da vez Não pretendo responder tudo que vocêpode ou deveria saber apenas o necessário Table of ContentsO que éIACO que éTerraformQuando eu deveria usar TerraformPor onde começarInstalaçãoA linguagem do terraformEstrutura do repositórioTerraform settingsProvidersBackendsTerraform stateVariablesDeclarando valores fixos para as variáveisLocalsResourcesModulesOutputsOutras coisas avançadasRepositório de exemploConclusão O que éIACAntes de seguir e falar especificamente do Terraform vamos entender um pouco sobre sua base Se vocêque estálendo jáformatou um computador pessoal sabe como pode dar trabalho instalar todos os softwares necessários para fazer alguma tarefa Agora imagine se o seu trabalho for provisionar computadores para um servidor ou uma aplicação e que vocêprecisa Criar máquinas virtuaisInstalar programas nelasCriar um banco de dados pra aplicaçãoFazer as configurações de rede e firewallNesse caso dependendo da quantidade de vezes que vocêfor fazer isso faz sentido pensar em automatizar certo Por causa disso ao longo dos anos surgiram várias ferramentas de automação para facilitar esse tipo de provisionamento A primeira que eu ouvi falar foi o Ansible da Red Hat A ideia éque vocêescreva arquivos de configuração definindo o que precisa ser criado e de forma simplificada qual a ordem das dependências Isso ajuda a subir infraestruturas de forma consistente O que éTerraformNas palavras traduzidas livremente por mim da Hashicorp empresa responsável pelo Terraform Terraform éuma ferramenta de infaestrutura como código que permite que vocêconstrua mude e versione infraestrutura de forma segura e eficiente A ideia ésimples vocêdescreve sua configuração em arquivos onde vocêescreve todos os recursos da sua infra máquinas virtuais configurações de rede bancos de dados virtualmente qualquer coisa O terraform usa a linguagem HCL Hashicorp Configuration Language nos seus arquivos e nele vocêdeclara os recursos que representam os objetos de infraestrutura Nós chamamos essa linguagem de declarativa o que significa que vamos escrever o que queremos que seja criado ao invés de escrever um “passo a passo um algoritmo de como as coisas devem ser executadas Quando eu deveria usar TerraformBom depende Minha recomendação éa seguinte Toda vez que vocêfor desenvolver um projeto que vai ou que pode ser implementado em mais de um lugar use Terraform Por exemplo se vocêestádesenvolvendo uma API ou um serviço e quer manter separados os ambientes de desenvolvimento e de produção usar o terraform vai deixar sua vida mais simples Se estiver trabalhando num projeto completo que vai ser implantado em nuvem também recomendo utilizar a ferramenta Vocêpode criar funções cloud functions do GCP ou lambda na AWS buckets de armazenamento do GCS ou do S automatizar a criação de arquivos de configuração Ou ainda deixar prédefinidas regras de rede de permissionamento Por onde começar InstalaçãoConsiderando o meu post sobre a configuração do windows para desenvolvimento vou explicar como instalar apenas em Linux Nesse caso basta acessar a documentação oficial e copiar e colar os comandos Assim sudo apt get update amp amp sudo apt get install y gnupg software properties common ywget O gpg dearmor sudo tee usr share keyrings hashicorp archive keyring gpggpg no default keyring keyring usr share keyrings hashicorp archive keyring gpg fingerprintecho deb signed by usr share keyrings hashicorp archive keyring gpg lsb release cs main sudo tee etc apt sources list d hashicorp listsudo apt updatesudo apt get install terraform yterraform install autocompletePara verificar a instalação basta executar o comando terraform v A linguagem do terraformA configuração do Terraform éum documento ou conjunto de documentos que diz ao Terraform como gerenciar a coleção da infraestrutura A sintaxe da linguagem consiste em alguns elementos básicos lt TIPO DE BLOCO gt lt TIPO RÓTULO DO RECURSO gt lt RÓTULO DO RECURSO gt Block body lt IDENTIFICADOR gt lt EXPRESSÃO gt Argument Exemplo retirado da documentação oficial Eu sei que isso parece um pouco confuso então a partir de aqui vamos trabalhar com exemplos Estrutura do repositórioAntes de realmente falar sobre o terraform vamos apresentar o repositório que estou trabalhandoassets code zipsrc index js package jsonterraform dev versions tf provider tf backend tf variables tf main tf terraform tfvars gitignoreREADME md Terraform settingsO primeiro passo édefinirmos as “dependências da nossa configuração Isso porque os recursos módulos e provedores podem ter versões diferentes Eu costumo criar o arquivo versions tf com esse pedaço de códigoterraform required version gt required providers google source hashicorp google version gt Nesse bloco nós podemos definira versão do próprio terraform com a qual nossa configuração funciona nesse caso uma versão maior que a os provedores que nossa configuração vai usar No exemplo de hoje apenas o de google cloud Mas aqui poderia entrar o provedor de AWS ou ainda de Kubernetes ProvidersO passo seguinte após definirmos as versões que vamos utilizar como base para nossa configuração éconfigurar os providers que estamos usando Esse tipo de configuração vai variar para cada provedor mas no caso do de Google Cloud podemos fazer assim no arquivo provider tfprovider google project var project id region var region zone var zone Aqui definimosQual o projeto do GCP onde as coisas serão criadasQual a região padrão dos recursosQual a zona padrão dos recursosComo peguei o exemplo de um projeto real ao invés dos valores literais nós temos configurações com a palavra var A ideia éque esse tipo de configuração seja gerenciada em um outro lugar então vamos deixar assim por hora BackendsHonestamente essa éa configuração mais importante para mim O objetivo do terraform pode ser automatizar o gerenciamento da infraestrutura mas por padrão ele armazena o resultado da configuração no seu computador Terraform stateNão mencionei antes porque raramente precisamos nos preocupar com esse arquivo Como expliquei brevemente acima o terraform armazena o resultado da sua execução num arquivo que normalmente fica no seu computador no mesmo diretório onde estáa configuração Esse arquivo éo state ou estado Ele vai ser um registro de toda a infraestrutura atual feita pela sua configuração contendo todos os recursos que vocêtem Quando vocêfizer uma alteração na configuração e aplicar novamente o terraform vai comparar a configuração com o estado para procurar por alterações E nesse caso vai mexer somente no que mudou Isso éimportante porque a configuração do terraform não tem acesso a sua infraestrutura em si apenas ao que ele gerencia através do estado Então por exemplo se eu aplicar uma determinada configuração no meu projeto e uma outra pessoa do mesmo time tentar aplicar a mesma configuração com certeza vão acontecer vários erros de “recurso jáexistente Para mitigar esse tipo de problema recomendo a utilização dos backends Com essa função o estado do terraform éarmazenado em um local remoto e vai ser acessado por todos que tiverem a configuração Isso também éimportante caso sua infra esteja configurada em alguma pipeline de CI CD Agora voltando ao backend como estamos fazendo um projeto de Google Cloud vamos usar o Google Cloud Storage gcs para armazenar nossos estados Éimportante ressaltar que o bucket do storage que vai armazenar o estado jáprecisa existir pois o terraform não vai criar por você No meu exemplo vamos criar o arquivo backend tfterraform backend gcs bucket py project terraform states prefix example dev Esse bloco de backend poderia estar junto das outras configurações de terraform mas eu costumo manter separado por questão de organização Aqui nós definimos O id do bucket onde nossos arquivos serão armazenadosO prefixo na prática a “pasta onde os arquivos serão criados Esse parâmetro éopcional mas considerando que um projeto pode ter múltiplas configurações de terraform considero uma boa prática definir o prefixo VariablesTodas as etapas anteriores são configurações nas quais vocêraramente precisarámexer e por isso gosto de mantê las em arquivos separados A partir daqui vamos lidar com as configurações que vamos escrever enquanto desenvolvemos nosso código Começo falando das variáveis justamente porque usamos algumas lána configuração do provider então geralmente começo com um arquivo variables tf com as seguintes configurações variable project id description Insira o ID do projeto do Google Cloud Platform type string variable region description Insira a região padrão para os recursos do projeto type string default us central variable zone description Insira a zona padrão para os recursos do projeto type string default us central a A declaração de variáveis ésimples Nós usamos o bloco variable e definimos o rótulo como sendo o nome da variável Dentro desse bloco nós podemos passar as configuraçõestype que define o tipo da variável O terraform vai validar se o valor passado bate com esse tipodescription que vai aparecer num prompt para o usuário na hora da aplicação da configuraçãodefault o valor padrão da variável caso o usuário não passe um Declarando valores fixos para as variáveisQuando vocêtentar aplicar uma configuração de terraform com variáveis o primeiro passo após a validação de erros na configuração éa verificação de variáveis Por padrão vai aparecer um prompt interativo para que o usuário preencha as variáveis uma por uma Como eu tento deixar o máximo possível de configurações dentro das variáveis esse processo pode ficar trabalhoso Fora que caso queiramos automatizar a execução do terraform esse prompt pode atrapalhar Para resolver isso podemos criar um arquivo terraform tfvars O terraform vai buscar no arquivo de extensão tfvars os valores para as variáveis declaradas Então para as variáveis de exemplo acima podemos ter um arquivo assim project id cadumagalhaes terraform example E dessa forma ao executar a nossa configuração o id do projeto jáseráconhecido LocalsAlém das variáveis declaradas como variables podemos criar variáveis temporárias usando o bloco locals Esse tipo de configuração éinteressante para os casos em que vocênão quer que o usuário que vai executar a configuração possa alterar seus valores pelo menos sem alterar a configuração em si Eu costumo usar para valores estáticos que posso usar múltiplas vezes como o nome de uma imagem docker Para o exemplo de hoje vamos armazenar o caminho da raiz do nosso repositório isso vai ser utilizado mais tarde Para o caso desse tipo de configuração não costumo colocar em arquivos separados Hoje vamos criar todas as próximas configurações dentro do arquivo main tflocals root dir abspath Aqui podemos declarar quaisquer variáveis com valores fixos para usar dentro da nossa configuração ResourcesAgora a parte mais importante que édescobrir como vamos realmente criar os recursos que precisamos no nosso projeto Aqui a receita ésimples Decidir o que precisa ser criadoPesquisar no google terraform recurso que vocêquer Entrar na documentação oficial do terraform Por exemplo para criar uma google cloud function Nesse caso o primeiro link éa página do módulo completo de Cloud Functions com uma documentação mais “bonitinha e formatada Eu costumo entrar no segundo link que éo do recurso porque ele jávem com vários exemplos de implementação e links das documentações do google Aqui nós podemos ver que a sugestão da documentação éque nós criemos mais um bucket do cloud storage em seguida nós fazemos upload do nosso código fonte para esse bucket e por último criamos a cloud function No nosso caso o arquivo main tf ficou assimlocals root dir abspath resource google storage bucket bucket name test bucket location var region resource google storage bucket object archive name code zip bucket google storage bucket bucket name source local root dir assets code zip resource google cloudfunctions function function name function test description My function runtime nodejs available memory mb source archive bucket google storage bucket bucket name source archive object google storage bucket object archive name trigger http true entry point helloGET ModulesIsso éum assunto pra outro dia pois não acho que sejam necessários para começar a usar Terraform Um módulo équando vocêencapsula um conjunto de recursos e configurações que podem ser reutilizados apenas trocando suas variáveis Por exemplo no caso acima nós poderiamos ter criado um módulo que cria uma Cloud Function e ao invés de declarar os recursos bucket arquivo e function declarar somente o módulo OutputsOs outputs são como variáveis que são criadas pela nossa configuração e que queremos expor de alguma forma Num módulo o output poderia ser o nome do recurso por exemplo Aqui no nosso exemplo como temos uma Cloud Function que éacionada por HTTP podemos definir como output o endereço dela No final do main tfoutput function url value google cloudfunctions function function https trigger url Dessa forma quando a configuração terminar de ser executada teremos o link da Cloud Function no nosso terminal Outras coisas avançadasO Terraform tem várias funções prontas para gerar um valor aleatório por exemplo expressões condicionais de repetição criação de templates de string Apesar de ser uma linguagem declarativa podemos criar configurações bem poderosas e resilientes usando esse tipo de feature Repositório de exemploO código completo com o exemplo estáno meu github cadumagalhaes terraform gcf nodejs exampleVale ressaltar que essa Cloud Function precisa de autenticação para ser executada Para testar vocêpode executar o comando abaixo no seu terminalcurl H Authorization bearer gcloud auth print identity token FUNCTION URL Isso vai gerar o token necessário para autenticação e fazer a chamada HTTP usando o curl ConclusãoComecei a trabalhar com Terraform no inicio do ano passado não sabia absolutamente nada e sinceramente nós apanhamos um pouco pra deixar a configuração pronta O conteúdo que coloquei aqui ébasicamente o que eu precisei para conseguir usar de forma confortável em projetos novos e ter dor de cabeça Confesso que não usei muitos conteúdos não oficiais sobre o assunto então se tiver alguma recomendação deixa aqui em baixo Como sempre tem um video muito bom disso láno canal da LINUXtipsDescomplicando o Terraform HashiWeekMe diz o que vocêachou desse tipo de post e se vocêgostaria que isso virasse um vídeo no Youtube Independente do resultado pra ajudar a decidir sobre o que seráo próximo post me acompanha láno twitter Espero que isso tenha sido útil para alguém atéa próxima	2023-07-11 21:06:03

similarly elegant design for less cash with a faster M chip superior display and wider accessory support than the th gen and th gen iPads Apple iPad th gen The GB th gen iPad is down to a new low of which is about off the average street price we ve seen in recent months The GB model is also down to a new low at Our review gave this inch iPad a score of last year This tablet sits in an awkward middle ground between the inch iPad and the iPad Air It has a faster chip more modern design and a larger screen than the former but it lacks the laminated display and broader accessory support of the latter Most notably it doesn t work with the second gen Apple Pencil If you can t spend more than though it s a clear upgrade over the th gen model And since it s the only iPad with a front camera on its landscape edge it s particularly convenient for video calls Apple iPad MiniThe iPad Mini is also down to an all time low of That s roughly off the inch tablet s typical street price and off Apple s MSRP We gave the latest Mini a score of back in but it remains the best compact tablet on the market as it s essentially a smaller version of the iPad Air It uses Apple s A Bionic chip instead of the more powerful M but the former is still plenty quick for most needs The big downside as with most non Pro iPads is that it only has GB of storage by default For more space the GB variant is on sale for a new low of Apple iPad Pro inchThe inch iPad Pro meanwhile is down to That s nbsp off Apple s list price for the jumbo sized tablet though it s a deal we ve seen fairly regularly in recent months The inch Pro has all the hardware upgrades of its inch counterpart but its “Liquid Retina display offers better brightness and contrast thanks to its Mini LED backlighting It s the closest any iPad comes to being a full on laptop replacement though iPadOS still has its share of issues with multitasking and productivity Still if you just want the most luxurious iPad possible or if a tablet fits better into your workflow than a traditional notebook it s worth considering Amazon Fire HD Amazon s Fire HD tablets are worth a look if all you want is a competent device for basic streaming and web browsing for as little as possible The Fire HD is the best value in the lineup for most people and it s back down to its all time low of for Prime Day This GB model usually costs around The GB version is also on sale for All Fire tablets are a step down from an iPad in terms of performance and build quality and their OS still pushes you toward Amazon apps like Kindle or Prime Video The app store is far less robust in general with no official support for Google services like YouTube or Gmail You ll also have to deal with lock screen ads unless you pay an extra fee But the Fire HD s inch p display is nice enough for casual media consumption and its processor is fast enough to not be a dealbreaker Plus its matte plastic design is comfortable it gets a solid or so hours of battery life and it has a microSD slot for adding storage This version of the Fire HD released back in but it s still hard to do better at this deal price We ll also note that the Fire HD Plus is on sale for This variant adds an extra gigabyte of RAM GB total and wireless charging support It might be compelling if you want to buy a charging dock and use the tablet like an Alexa smart display but the base model should be enough for most people in need of an affordable tablet Amazon Fire HD Kids and Kids ProThe Fire HD Kids and Kids Pro are each down to matching their lowest prices to date These devices have similar hardware as the base Fire HD but like all of Amazon s Kids tablets add a protective bumper case built in kickstands a longer two year warranty and a year to Amazon s Kids service which includes a variety of child friendly books games and apps They ship with a simplified UI by default and mercifully they don t feature ads on the lock screen Between the two the Kids edition has a larger rubbery case while the Kids Pro model has a slimmer hard plastic case designed for slightly older children If you re not comfortable giving your kid an iPad these are decent substitutes Amazon Fire HD If you re on a super tight budget the Fire HD is a decent value at which again matches the best price we ve seen Normally this tablet retails around It has a smaller inch and lower resolution x display than the Fire HD and it s not as quick in day to day use but its performance is adequate for the basics it still gets ish hours of battery life and it s light in the hand Amazon Fire HD PlusAmazon also makes a Plus model of the Fire HD with GB of RAM instead of two wireless charging support and a marginally better camera Given that the Fire HD isn t all that fast the Fire HD Plus might be worth the step up if you have a little more to spend The GB model is now on sale for which is only more than its all time low and percent off Amazon s list price Amazon Fire HD Kids and Kids ProThe Fire HD Kids and Kids Pro are both available for That marks a new low and comes in below their average going rate These two come with the same extra features as the Fire HD Kids models above but they use the Fire HD as their base so they aren t as fast or spacious If you want to save some cash on a streaming and reading machine for your kid though they re solid values at this price Samsung Galaxy Tab SSamsung s Galaxy Tab S is on sale for which matches the best price we ve seen outside of trade in deals We ve typically seen this inch slate retail around in recent months The Galaxy Tab S line is the top Android pick in our guide to the best tablets thanks to their lively displays and robust S Pen stylus support The base Tab S has an LCD panel with a fast Hz refresh rate and sharp x resolution along with a speedy Snapdragon Gen processor and GB of RAM Samsung says it will supply software updates to the Tab S lineup through early as well That said you should only get this if you re deeply committed to Android Google s OS still isn t as accommodating to productivity as iPadOS or Windows nor does it have as many apps that are explicitly designed for large screens But if you own a Galaxy phone or just don t want to jump into Apple land this is still good hardware Samsung Galaxy Tab S The inch Galaxy Tab S is available for which is more than below its usual street price and matches its all time low This variant has the same general strengths as the standard Tab S but it has a more vibrant OLED display that ranks among the best on any tablet plus it s slightly thinner instead of It also has a larger battery to make up for the bigger display Again though this is a good chunk of change to spend on an Android slate Like the standard Tab S it also lacks a headphone jack We gave the Galaxy Tab S a review score of last year Microsoft Surface Pro The Surface Pro is the top Windows pick in our tablet buying guide and a configuration that includes a Core i U processor GB of RAM and a TB SSD is now on sale for Clearly that s not cheap but it s off this model s recent street price and represents a new low You probably know where you stand on the Surface Pro at this point It s still not particularly comfortable to use on your lap but it remains the gold standard for in s that behave and perform like a laptop more than a traditional tablet While this version isn t a huge shake up it should be a nice bump for those upgrading from a three to five year old model Just note that this deal doesn t include a keyboard or stylus Amazon Fire Max The recently released Fire Max is down to which is the first major discount we ve seen and percent off this slate s standard going rate This is the largest and most powerful tablet Amazon sells with an inch x resolution display and a beefier octa core processor than the one in the Fire HD Its chassis is made of aluminum instead of plastic as well The issue is that it still runs Fire OS whose shortcomings in app support and productivity features plus its built in ads are harder to swallow when you re spending more than to use it But if you re in the niche group that wants a more premium Fire tablet without spending iPad or Galaxy Tab money it could have appeal Your Prime Day Shopping Guide See all of our Prime Day coverage Shop the best Prime Day deals on Yahoo Life Follow Engadget

in our earbuds guide and represent a big improvement over the first iteration with better noise canceling and overall improved sound They have an excellent transparency mode that lets you listen to music while still keeping aware of the sounds around you and they pair nicely with iPhones iPads and Macs and make good use of Siri s assistance We gave them an in our review noting the sound quality

our full review of the Apple AirPods Pro nd gen AirPods rd gen Apple s updated AirPods have been discounted to for Prime Day Released in these wireless earbuds improve upon their predecessors in

price for iPhone users AirPods nd gen The second generation AirPods are down to for Prime Day These wireless earbuds are a bit old at this point but if you have less than to send and want a pair that work seamlessly with iPhones and other Apple devices these are a good option They fit similarly to Apple s EarPods and they have improved wireless range iPad AirThe latest iteration of Apple s iPad Air is after a discount We think it s the best iPad for most people It came out in and features Apple s own M system on a chip processor and a bright and sharp inch display We gave it a review score of noting that the updated chip and G capabilities on the cellular model make it “almost future proof It s great for playing games and watching shows but when you pair it with accessories like a keyboard the iPad Air can easily handle productivity tasks like writing drawing moderate photo editing and running work related apps like Airtable and Slack Plus it s much cheaper than the iPad Pro which may be overkill for many users Read our full review of the iPad Air iPad th gen Apple s th generation iPad is down to which it s best price yet as it normally sells for It s the budget pick in our guide to the best iPads Though it doesn t have the thin bezels and as much accessory support as our favorite the iPad Air it s the most affordable way to snag an iPad It s a great couch companion that performs well for casual browsing binge streaming and light gaming nbsp Read our full review of the th gen iPad The latest th generation of Apple s standard iPad in the GB size is down to after a discount It s got a slightly larger screen and a newer chip though not Apple s own M series silicon The latest gen slab also ditches the home button which is nice but does away with the headphone jack which isn t as great MacBook Air MIf you want a steep bargain on an Apple laptop go for s MacBook Air with the M chip It s still a capable laptop and the GB base model is just for Prime Day which is the lowest price we ve seen so far on the ultraportable It s the budget pick in our buyer s guide to Macbooks and earned a high score of in our review The performance of the M chip really makes the MacBook Air M stand out It s responsive launching apps quickly and running them effortlessly The M chip is also behind the MB Air s great battery life We clocked hours and minutes of play time in our video rundown test which should be more than enough to get you through a full day of work or study Read our rather glowing review of the MacBook Air with the M chip nbsp iPad miniA smaller tablet like the iPad mini can do a lot of what your phone can while giving you more screen real estate For Prime Day Apple s diminutive slate is for Prime members instead of its usual We gave the mini an in our review because of its fresh design and solid performance It also pairs nicely with the second generation Apple Pencil turning the mini into a portable digital notebook The iPad mini comes with a MP ultra wide front camera that supports Center Stage a feature that pans and zooms to keep you in frame during video calls As for battery life Apple estimates going for hours on a charge but we got two hours longer than that on our video run down test and only had to charge it every other day with casual but regular use nbsp Read our full review of the iPad MiniApple Pencil nd gen The latest Apple Pencil is usually but Prime Day is making it just The second generation of the stylus works with the most recent models of the iPad mini the iPad Air and both sizes of the iPad Pro The standard iPad even the latest iteration still works with the first generation Apple Pencil which is right now The Apple pencil lets you draw sketch take handwritten notes and even write in search boxes The second gen pencil magnetically attaches to and charges from all compatible iPads Magic KeyboardThe Magic Keyboard for the iPad Air or the inch iPad Pro is now just as opposed to the list price The keyboard wraps around and magnetically attaches to your iPad acting as a case when closed then when it s time to type your tablet “floats above the keyboard It s one of our favorite iPad accessories and in our review of the iPad Pro we noted the Magic Keyboard “provides the best typing experience for Apple s tablets The keyboard for the inch iPad Pro is also on sale and going for for Prime Day AirTagsApple s AirTags are discounted less than for the four pack Compared to the usual per tag price that s a decent savings We named the AirTags the best bet for iPhone users because they tap into Apple s vast Find My network pinging off nearby Apple phones to anonymously locate the tracker if it s ever lost out in the city Apple Watch Series Apple s flagship smartwatch is the Apple Watch Series and Prime Day is giving it a discount Usually the mm GPS model is now The Series is our favorite smartwatch thanks to its detailed health and fitness tracking along with a seamless integration with your iPhone s apps and notifications New features like temperature sensors ECG and blood oxygen readings and improved sleep metrics give you more data than ever while the crash detection can call for help if you re ever in an accident The upcoming WatchOS will add widgets and expanded features including ways to track your mood in the Mindfulness app The cellular enabled models are also on sale Those watches can make calls get texts and more when you don t have your phone The mm GPS plus cellular Series is instead of and it s for the mm size as opposed to the usual Apple Watch SEThe most affordable smartwatch in the lineup is the Apple Watch SE The mm case size went out of stock for a bit but has returned and is just for Prime members which is the lowest price we ve seen on the wearable The larger mm case is also on sale It s usually Prime Day discounts are making it just We called the SE “the best smartwatch can buy in our Engadget review It makes surprisingly few sacrifices over the Series and shares the same looks processor and meter water resistance It doesn t have an always on display and lacks the sensors for blood oxygen temperature and EKG readings If you don t need all that you can still get scads of fitness and health data plus seamless integration with your iPhone Our reviewer Cherlynn Low notes that Apple made surprisingly few sacrifices with the SE and named it “the best smartwatch for the money In fact in the wrap up to her Apple Watch coverage she said if she were shopping for herself the SE is the watch she d buy The cellular models are also on sale for Prime Day The GPS plus cellular model lets you take calls text and stream music even when your iPhone isn t with you They start at for Prime Day Read our full review of the Apple Watch SE MacBook Pro M inch The MacBook Pro offers music makers video producers and other heavy users a lot of processing power with the M Pro and M Max chips Amazon is selling the base model inch MacBook Pro with the M Pro chip GB of memory and GB of storage for which is off the usual The base model inch MacBook Pro with the same specs is down to instead of When the new MacBook Pros came out in January of this year we gave the inch model a review score praising the Liquid Retina XDR display sturdy design and plethora of ports including three Thunderbolt USB C HDMI a headphone jack and a full sized SD card slot Read our full review of Apple s inch MacBook Pro nbsp The inch MacBook Pro is also on sale for after a discount but we re not as impressed with this machine If you re happy with a inch screen you re probably better off going with the inch MacBook Air AirPods MaxApple s over ear headphones the AirPods Max are on sale for which is off the usual They earned an in our review when they came out at the end of We liked the balanced sound solid active noise cancellation and long hour battery life with a unique low power mode that leaves the headphones in standby so they re ready to play as soon as you put them on Apple Studio DisplayThe usual for the Apple Studio Display is pretty steep Prime Day has brought the price down to which makes it a little more palatable but we still think the display is ideal only for true Apple devotees The A Bionic chip inside makes it a little smarter than most displays but the Hz refresh rate is disappointing Still it s got a nice build with good speakers and a

海外TECH	Engadget	The best gaming deals for Amazon Prime Day 2023	https://www.engadget.com/amazon-prime-day-gaming-deals-132537938.html?src=rss	The best gaming deals for Amazon Prime Day Amazon Prime Day has brought several discounts on gaming gear we like from mice and keyboards to laptops and headsets If you ve been looking to build out your gaming rig now s a great time to pick up a few high performing accessories or even a bigger investment like a discounted gaming laptop We ve compiled the best Prime Day gaming deals we can find below including peripherals from Razer Logitech SteelSeries HyperX and more Logitech G Pro X SuperlightThe Logitech G Pro X Superlight is back down to an all time low of which is about off its average going rate This is a high end wireless mouse whose praises we ve sung in the past It s sturdily built and wonderfully light at roughly g and its mostly ambidextrous shape should be suitable for most hand sizes Performance is exceptional across the board and while it lacks RGB lighting it won t look gaudy in an office setting To be clear the Razer DeathAdder V Pro which isn t notably discounted for Prime Day remains our favorite premium model as it lasts longer on a charge and uses USB C instead of the microUSB port found here Still the G Pro X Superlight is a fine choice for enthusiasts Logitech G LightspeedThe Logitech G Lightspeed is a budget wireless gaming mouse we highlight in our buying guide and it s down to for Prime Day While that s a few bucks more than the lowest price we ve seen it s about less than the mouse s usual going rate The G is on the smaller side but its symmetrical design doesn t feel particularly cheap and should accommodate most claw and fingertip grippers For the money its sensor performance is great It does require a single AA battery for power so it isn t the lightest option at roughly g but Logitech says it can last up to hours before needing a change If you re willing spend a little bit more the Razer Basilisk V is the top pick in our guide and it s down to a new low of at Best Buy While that s not a Prime Day deal it s a great value for an ergonomic mouse that tracks reliably and should be comfortable for most hand sizes It has a more versatile scroll wheel that can tilt left to right and utilize a faster free spin mode too nbsp Nintendo Switch gamesIf you need something new to play a handful of popular Switch exclusives are at or near their lowest prices to date Super Mario Odyssey Mario Kart Deluxe New Super Mario Bros U Deluxe Mario Golf Super Rush nbsp are each down to while the turn based strategy game Mario Rabbids Sparks of Hope nbsp is available for Outside of Amazon Metroid Dread and Pokémon Legends Arceus nbsp are both down to at GameStop while Best Buy has the exercise RPG Ring Fit Adventure for Most of these games are a few years old but steep discounts on Nintendo games are still fairly uncommon Beyond the Switch the action RPGs Elden Ring and Horizon Forbidden West nbsp are each down to while the more recent Star Wars Jedi Survivor is available for with an on page coupon Samsung Evo SelectThe GB Samsung Evo Select is available for which is a new all time low Typically we ve seen this microSD card go for or nbsp more in recent months The Evo Select is the “best value pick in our guide to the best microSD cards It s certainly not the fastest card we ve tested but it s a great buy for expanding the storage of a Steam Deck or Nintendo Switch Both of thosesystems are limited to official UHS I bus speeds so game launch and load times are virtually identical across microSD cards so long as your card meets a certain threshold which the Evo Select does What you mainly want is lots of storage space for a little amount of money At this price the Evo Select provides that If you need more space the TB SanDisk Ultra is also worth a shout at which is an all time low This card is slower than the Evo Select which is already a budget model so it may be a little too sluggish to install games for comfort But for TB is a fantastic value The top pick in our microSD card guide Samsung s Pro Plus is a bit pricier but still down to all time lows of for GB and for GB While this won t be any faster to launch Switch or Steam Deck games than the Evo Select its superior random and sequential write speeds should make it a little quicker for installing games or copying files to the card Samsung ProThe TB Samsung Pro SSD is down to which is its lowest price ever and about off its average street price as of late This isn t Samsung s fastest SSD that d be the Pro but we highlight it here because it meets Sony s requirements for expanding the PS s storage You ll want to grab a heatsink to go with it but you can do that and still pay less than what it d cost to buy the variant that comes with a heatsink pre installed Xbox Gift CardHere s a simple one Amazon is selling Xbox digital gift cards available for each If you already plan on renewing a Game Pass membership or buying a few digital games for your Xbox Series X in the near future this is effectively a free Sennheiser HD SA good set of open back headphones generally provides much better audio quality than a conventional gaming headset for around the same price The Sennheiser HD S is one such pair we recommend in our guide to the best gaming headsets and now it s down to That s about below its typical street price There s no mic here but the HD S balanced sound profile and wide soundstage lend games a lovely sense of immersion and detail It s great for music as well even if it can be a smidge hot in the treble Comfort also isn t an issue but be aware that all open back headphones let in and leak lots of external noise so they won t be ideal if you play in a noisy environment HyperX Cloud Alpha WirelessIf you want a more traditional gaming headset the top wireless pick in our guide the HyperX Cloud Alpha Wireless is on sale for That s less than its traditional street price This pair is all about the battery life as it can last more than hours on a charge No that s not a typo The bass boosted sound isn t as accurate or spacious as a good open back pair and HyperX s companion app is kind of a mess but the design is comfortable the mic is fine and the battery goes a long way toward minimizing the usual inconveniences of a wireless headphone Just note that the headset only connects over a USB wireless dongle and doesn t work with Xbox HyperX Cloud Stinger The HyperX Cloud Stinger is also on sale for a new low of This is the budget pick in our buying guide It s not particularly balanced sounding but it gives action scenes an exciting sense of impact and its mic quality belies the low price The plastic frame doesn t clamp down too hard either but it does feel somewhat cheap The original Cloud Stinger is also on sale for which is a great price though the newer model sounds better Logitech GThe Logitech G is on sale for which is the second best price we ve tracked outside of a very brief dip below last month Normally it costs around The G is an honorable mention in our buying guide It s light and airy at g and while it can make mid range details sound thin it has an agreeable and relatively well balanced sound overall The included boom mic is just OK however and the closed back design doesn t block much outside noise Still finding a good wireless gaming headset for less than is difficult and the G gets close enough SteelSeries Arctis Nova ProThe SteelSeries Arctis Nova Pro is another honorable mention in our gaming headset guide and it s down to for Prime Day This is an all time low for both the Xbox and PlayStation PC models each typically goes for about more on average This is a premium well padded headset that s comfy to wear over long sessions Its retractable mic is great and it comes with a DAC that lets you adjust the headset s EQ and game chat audio mix on the fly It does well to reproduce bass and mid range sounds too though it can be harsh in the treble and again it doesn t sound as spacious as an open back pair like the Astro A our top pick which isn t any cheaper than usual for Prime Day Still if you have money to burn on a gaming headset and prioritize comfort and mic quality this isn t a bad choice SteelSeries Arctis Nova XThe SteelSeries Arctis Nova X meanwhile is available for which is the lowest price we ve seen and about below its usual street price We note the Arctis Nova X in our gaming headset guide as a worthy wireless option for Xbox owners Its mic quality is solid albeit worse than the pricier Nova Pro and it s comfy to wear over time with cloth earpads that don t clamp down too hard It has a bass forward sound profile so explosions and other effects carry a real sense of oomph though a dip in the treble can make in game dialogue sound underemphasized The pair can connect over Bluetooth or a mm cable in addition to its wireless dongle though plus it can last more than hours on a charge Seagate Storage Expansion Card for Xbox Series X S TB For better or worse the only way for Xbox Series X S owners to fully expand their console s storage for current gen games is to use a proprietary storage card Seagate s Storage Expansion Card is one of the few official options but right now a TB model is down to a new low of While that s still pricey compared to a traditional and PS compatible SSD it s at least a little bit of savings for those tired of uninstalling games to save space Razer Huntsman MiniThe compact Razer Huntsman Mini is down to for a model with either Clicky Purple or Linear Red opto mechanical switches Neither deal is quite an all time low but the two models have usually retailed in the to range over the last few months The Huntsman Mini is the top pick in our guide to the best percent keyboards as its keys are pleasant and consistently responsive for gaming The whole thing feels well built with quality PBT keycaps and RGB lighting on a per key basis Each key can be programmed through macros as well The switches here aren t ideal for those who like a springy and more tactile though and the ultracompact design won t be for everyone HyperX Alloy Origins The HyperX Alloy Origins is the runner up in our percent keyboard guide and it s on sale for That s about off the usual price for this model with HyperX s Aqua switches The Aqua resembles a Cherry MX Brown albeit slightly faster so this deal should appeal to those who want a small gaming keyboard with a more tactile feel than the Huntsman Mini The board itself has a sturdy aluminum chassis that should hold up well to rough keystrokes over time plus it puts its secondary arrow keys in a natural spot at the bottom right of the deck It offers PBT keycaps per key RGB lighting and macro programmable keys as well though the use of metal does make it relatively heavy SteelSeries Apex Pro TKLThe SteelSeries Apex Pro TKL is on sale for which is a new low and nbsp off the tenkeyless gaming keyboard s list price While we haven t reviewed the Apex Pro TKL ourselves it has received consistentlyhighmarkselsewhere for its robust build quality PBT keycaps per key backlighting and deeply adjustable OmniPoint switches The latter allows you to customize the actuation point of each individual key in increments of mm within a range of mm mm You can make each keystroke super fast for gaming or raise the travel distance and make everything less sensitive when you want to type This is also one of the few tenkeyless keyboards that comes with a wrist rest A few other variants of the Apex Pro are discounted too including the wireless TKL model for the full size Apex Pro for nbsp and the percent Apex Pro Mini for The first two of those are down to all time lows but note that the full size model uses cheaper ABS keycaps These are pricey and relatively niche keyboards either way but if you think you d benefit from the customization they re at least a little more affordable now The Asus ROG Azoth is another highlyratedcompactkeyboard with enthusiast level features like a gasket mounted design for softer typing and a hot swappable PCB It s available for nbsp with a coupon which is a serious chunk of change for a wireless keyboard but less than usual Logitech G TKLThe Logitech G TKL is down to nbsp for a model with tactile switches which matches the keyboard s lowest price and comes in about below its usual price If you want a numpad the full size G Lightspeed with linear switches is roughly off at The G is worth considering if you specifically want a wireless keyboard with low profile typing experience While its flatter keys may not feel as smooth as the best full height keyboards they re fast and the metal frame is noticeably slim The cheaper ABS keycaps and limited macro functionality are disappointing at this price but you do get dedicated media controls per key RGB lighting and hours of battery life with the backlight at max brightness You can read our write up for more details Meta Quest Amazon gift cardThe Meta Quest is on the horizon but the Quest s totally cordless design still competent hardware and relatively large app library make it the best option for most people looking to get into VR today It can also connect to a gaming PC if you want to play more complex games like Half Life Alyx The headset itself isn t priced any lower than usual for Prime Day but Amazon is throwing in a gift card for no extra cost nbsp Razer Blade laptopsA configuration of the Razer Blade with a Core i H processor GeForce RTX Ti GPU Hz QHD display GB of RAM and TB SSD is down to for Prime Day That s about off its usual street price in recent months We gave the Blade a review score of last year and we currently recommend it as a premium pick in our guide to the best gaming laptops This config is a model the latest version is largely a spec bump but it ll still be powerful enough to play most modern games at high settings and frame rates particularly with DLSS The main reason to pay the premium for any Blade laptop though is because it packs that power in a slim and premium feeling aluminum design Just note that it can run hot and that its battery life is fairly short If you want a larger inch display a version of the Blade with similar specs is available for The smaller Blade meanwhile is more modestly discounted at for a config with a Ryzen HX RTX Ti and Hz display Acer Nitro The Acer Nitro is the runner up pick in our guide to the best budget gaming laptops and right now a configuration with a Core i H GeForce RTX Ti Hz p display GB of RAM and GB is available for That s a new low and roughly off this model s typical street price This is a chunky plastic machine and you ll need to ratchet down the settings in certain games to hit a decent frame rate But getting a Hz display and enough power to keep up with modern games is a plus at this price As an affordable yet competent entry point to PC gaming it s a fine value Your Prime Day Shopping Guide See all of our Prime Day coverage Shop the best Prime Day deals on Yahoo Life Follow Engadget for the best Amazon Prime Day tech deals Learn
