海外TECH	DEV Community	Hardware 101 - CPUs, Cores and Threads	https://dev.to/vsaw/hardware-101-cpus-cores-and-threads-2mhg	Hardware CPUs Cores and ThreadsIn this post I m going to give you a beginner friendly introduction into how modern CPUs Intel Apple AMD ARM etc work CPUsLet s start with the CPU The CPU is often referred to as the Brain of your computer but what does this mean The CPU does most of the computation on your computer It runs your Web browser Office etc Basically everything except Graphics amp Machine Learning this usually runs on the GPU The difference between the CPU and GPU is that the CPU is good for a generic computing The GPU is a highly specialized chip which is GREAT for certain tasks like Graphics amp Machine Learning but also much more expensive Other then than the Brain neither the CPU nor the GPU actually store any data They just fetch it from memory process it e g math calculations and write it back to memory A CPU has multiple parts a Core that does the computationa Cache which you can imagine like super small but super fast RAMand a Memory I O so that me CPU can read and write from RAM and your hard drive CoresIn the beginning each CPU had only one Core but modern CPUs have multiple cores For example I m writing this post on an GHz Intel i CPU with cores Other CPUs like the AMD Ryzen x have cores But what does it mean if a CPU has more cores Can it then do more as well Yes and No Assume we have two identical Computers one with cores and one with cores Are there programs that the core CPU can t run No If there are more tasks then cores your OS will time share Time Share is when two or more programs share the use of a Core Time slots are super small lt ms per program so that programs switch all the time making it seem to humans as if they are running in parallel when in fact they are running sequentially This is a normal thing to do for computers E g My computer has cores but I have programs running more processes running in the background So more cores will not allow you to do more things They just allow you to run more things truly parallel So how many cores do you need This depends on the type of Software you are using Computationally intensive application like gaming or math simulations etc may run faster if you CPUs with more Cores Still CPUs with less cores do fine most of the time As I said my laptop has only cores and they are idle of the time while I write this Post ThreadsModern Cores have a special feature called Multi Threading To explain this we first need to understand what Processes and threads are Examples of Processes are your Music Player App and your Email App Processes can run in parallel and should be strictly separated by the Operating System and Hardware We don t want the Email App to mess up the Music Player or the other way around But looking at the Music player there is parallel computing going on in the Music player itself You can keep listening the the music while the User Interface reacts to your input while you browse your library This is done by using multiple Threads which run inside the Music Player process One thread keeps playing the music while the other thread takes care of the user interface Inside the Music Player we want Threads to be able to exchange information easily so the player starts playing a new song as soon as you double click it As threads are quite common modern CPU Cores have Hardware Support for it called Multithreading More Cores amp Threads More PerformanceMulti core CPUs and Multithreading can increase performance of your computer but only if you use them right Imagine a highwayCPU clock speed speed limitCores Threads Amount of LanesAdding a core thread potentially allows more cars to go through in parallel But it s not going to make the individual car go faster The overall throughput then depends on your “traffic Have loads of individual cars More cores can help Need to get one single car from A to B Then no By default processes start with a single thread It s up to the programmer to write programs that create child processes or multiple threads so they can take advantage of multi core and multithread CPUs Once you have implemented threading in your program a piece of the Operating System called the Scheduler will take over Each modern operating system has a Scheduler which decides which process and thread gets executed next based on available CPU resources and their priority For example with our Music player app we need the Thread playing the music to have high priority otherwise the sound comes out choppy For the User Interface however we could use a lower priority because worst case it takes a few milliseconds longer to load but users will not mind this as much This a longer more readable version of a Thread I posted on Twitter recently I don t always find the time to post all of my Twitter threads on Dev To so follow me on Twitter vsaw if you don t want to miss out on anything Valentin Sawadski he him vsaw Recently this thread trying to explain modern CPUs popped up in my feed and it got so many things wrong So here s a fact checked correct version of how CPUs and Cores amp Multithreading REALLY works twitter com DThompsonDev s… PM Sep Danny Thompson dthompsondev What is a CPU What are Cores What is threading and multi threading Lately I have been learning about hardware and about to build a PC but found myself completely confused So I ve spent a ton of time learning about hardware Here is your beginner crash course in CPU chips	2022-09-26 14:09:51
