海外TECH	Engadget	Microsoft unveils Copilot+ PCs with generative AI capabilities baked in	https://www.engadget.com/microsoft-unveils-copilot-pcs-with-generative-ai-capabilities-baked-in-170445370.html?src=rss	We ve been hearing rumblings for months now that Microsoft was working on so called AI PCs At a pre Build event the company spelled out its vision Microsoft is calling its version Copilot PCs which CEO Satya Nadella described as a quot new class of Windows PCs quot These contain hardware designed to handle more generative AI Copilot processes locally rather than relying on the cloud Doing so requires a chipset with a neural processing unit NPU and manufacturers such as Qualcomm have been laying the groundwork with chips like the Snapdragon X Elite nbsp Microsoft is taking a partner first approach to making Copilot PCs Along with chipmakers like AMD Intel and Qualcomm major OEMs including Acer ASUS Dell HP and Lenovo are on board nbsp Yusuf Mehdi Microsoft EVP and Consumer Chief Marketing Officer said during the event that the company has completely reimagined what a Windows PC is He claimed that Copilot PCs are the most powerful PCs ever we ll need to see if that assertion holds up in real world testing Despite that Mehdi said the first generation of laptops are quot unbelievably thin light and beautiful quot nbsp Other AI PCs on the market deliver TOPs tera operations per second To be dubbed a Copilot PC a system will need to deliver at least TOPs of NPU performance and have at least GB of RAM and GB of storage Qualcomm claims the Snapdragon X Elite delivers up to TOPs overall But the pure specs matter less than what Microsoft is able to actually do with the hardware Mehdi also suggested Copilot PCs are percent faster than M powered MacBook Airs though it s worth noting Apple has more powerful M chips in its laptops already and M chips on the way very soon The company suggested that Copilot laptops will offer up to hours of battery life while playing videos locally and up to hours while browsing the web To help make all of this happen the Windows Copilot Runtime has more than AI models that are part of a new Windows layer They re said to be deeply integrated into Windows to help them more efficiently access hardware and to power more robust privacy and security options The models can work across any app Microsoft says As far as the Windows features go one aspect of Copilot PCs is something that s been rumored for a while It s called Recall and you can think of it as a more advanced version of the Timeline feature from Windows You ll be able to use natural language prompts to get your PC to resurface information based on what you remember about it You ll be able to scroll through apps documents and messages on an explorable timeline According to Mehdi Microsoft built Recall with responsible AI standards in mind Data from it will stay on your PC and it won t be used to train Microsoft s AI models Additionally you ll be able to restore old snaps in Windows Photos using a tool called Super Resolution In addition the app will offer an option to tell a story based on your photos with the help of an AI narrator Live Captions meanwhile will offer real time captioning and translations into English from more than languages with more to come from both live and pre recorded video There s also a new Copilot app that you can use as a standalone window sidebar or in full screen You ll be able to drag and drop elements into Copilot from elsewhere in Windows Thanks to the new Copilot key on keyboards you ll be able to fire up the app with the touch of a physical button Copilot will eventually be able to let you adjust Windows settings too Given that Qualcomm uses Arm architecture it s perhaps little surprise that Microsoft has rebuilt Windows for Arm based chips Microsoft has been trying to make Arm based Windows PCs a thing for some time with mixed results We had major reservations about the Arm powered Surface Pro a couple of years ago But perhaps the company has finally cracked that nut this time around nbsp To help with that Microsoft has developed an emulator called Prism that is said to be as efficient as Apple s Rosetta The aim is to help users run older apps without a hitch Major apps such as Zoom Chrome and Photoshop will run natively on Arm based Windows The Copilot PC is the natural progression of something we ve seen in flagship Android phones over the last couple of years The most recent Google Pixel devices for instance handle many generative AI processes on device by tapping into the power of the company s Tensor chips Meanwhile Apple is largely expected to move into the generative AI space in a major way at its Worldwide Developers Conference next month The M chip that recently debuted in the new iPad Pro is said to be capable of powering GAI experiences and that chipset should be coming to Macs later this year Apple s also said to be working on a deal with OpenAI perhaps to bring its generative AI tech to
