Fallon / AFP via Getty ImagesThe company best known for powering the AI boom is coming for the PC: Nvidia is expected next week to debut the first Windows computers that use its chips as the main processor, sources confirm to Axios.Why it matters: Microsoft's first AI PC push stumbled, but Nvidia's arrival gives it a second chance, this time with the world's hottest chipmaker attached.Driving the news: Nvidia and Microsoft will unveil their joint work and the first computers running the chips at two key industry conferences — the Computex trade show in Taiwan and Microsoft's Build developer conference in San Francisco.Nvidia-powered PCs are expected both from Microsoft's homegrown Surface brand as well as other computer makers, including Dell, sources confirmed.Microsoft is also expected to debut software that makes it easier for people to have AI agents do work locally on their Windows computer.A Microsoft representative declined to comment. Dell declined to comment. Nvidia did not immediately respond to a request for comment.Catch-up quick: Nvidia, which got its start making PC graphics chips, has been working on entering the PC processor business for years now, though only recently has it become clear that the debut was imminent."A new era of PC," Nvidia teased in a Friday post on X, pointing to coordinates that match a location in Taiwan.Meanwhile. Windows head Pavan Davuluri engaged in his own vagueposting. "Something new is coming for developers," he said on X. "And no, it's not a new OS version. See you at Build next week!"The big picture: The move comes as Microsoft is trying to reposition Windows to take advantage of the massive momentum behind AI.Microsoft's first effort at an AI PC, the Copilot+ PC, was marred by a series of setbacks, including a lengthy delay and security concerns over its signature feature, Recall.However, the move toward agents that can automatically perform tasks on local PCs has provided what it sees as a fresh opening.The company has been embracing OpenClaw since earlier this year, creating a new team led by veteran coder Omar Shahine. The company also has OpenClaw founder Peter Steinberger (now employed by OpenAI) scheduled to host a breakout session at Build.Between the lines: While most AI work has been done in the cloud, Microsoft's push to have things run locally could find newly receptive ears.Businesses are starting to struggle with massive computing costs that have accompanied the shift from unlimited-use chatbots to agents, which can rack up giant bills as they do their autonomous work.What they're saying: Nvidia's entry in the PC market could help not only it and Microsoft, but also rival Qualcomm, which uses a similar type of chip as Nvidia rather than the traditional PC chip architecture used by Intel and AMD."From an industry perspective, it's a good thing," Carolina Milanesi, an analyst at Current Strategies, told Axios.Milanesi said that Qualcomm has struggled to grab a significant chunk of the PC market despite offering excellent battery life, in part because developers and businesses didn't see a need to focus scarce resources on a somewhat different version of Windows.As for Nvidia, Milanesi said getting its new processor used in the data center is the bigger opportunity, but powering PCs could be a nice complement.
