Nvidia Announces RTX Spark ‘Superchip’ for AI-Powered Windows PCs Nvidia’s long-rumored push into PC processors has arrived, setting up a three-way contest with Apple’s Macs and Intel / AMD-powered Windows machines over what an “AI PC” should be.

In late May, Nvidia, Microsoft, and Arm began openly hinting that new Arm-based laptop chips were coming, teasing “a new era of PC” ahead of Nvidia’s Computex keynote in Taipei. Axios soon reported that the first Windows PCs using Nvidia chips as the main processor would debut the following week, giving Microsoft “a second chance” at its AI PC push after early Copilot+ stumbles.

On June 1, Nvidia formally unveiled RTX Spark, a family of Arm-based “superchips” that combine a Grace CPU, Blackwell RTX GPU, and up to 128GB of unified LPDDR5X memory. The Verge reported Nvidia’s claim that RTX Spark is “the most efficient PC chip ever built,” designed to meet or beat the most powerful thin-and-light Windows machines and to run demanding tasks like 12K video editing and large AI agents locally. TechCrunch framed the launch as Nvidia chasing a new $200 billion CPU market, with AI “agent PCs” from ASUS, Dell, HP, Lenovo, Microsoft Surface, and MSI due this fall.

Microsoft quickly put itself at the center of the rollout. At Build, CEO Satya Nadella said the company’s goal is to “deliver unmetered intelligence to every home and every desk with Windows,” calling RTX Spark “a real breakthrough toward that vision.” The company announced the Surface Laptop Ultra, a 15‑inch RTX Spark flagship that Surface chief Andrew Hill described as “the most powerful thing we’ve ever made,” with graphics roughly comparable to an RTX 5070 laptop GPU and up to 128GB unified memory.

Across the industry, PC makers detailed their first RTX Spark laptops, all targeting creators, developers, and AI builders with high-end displays and configurations. Commentators compared the moment to Apple’s 2020 M1 transition, suggesting RTX Spark “could be Windows’ moment to blow us away,” while warning that high prices and still-unknown real‑world benchmarks may determine whether this AI-centric reboot of Windows on Arm truly sticks.
