Nvidia Unveils RTX Spark, Its First Complete PC Chip

Nvidia is expanding beyond AI data center chips into personal computers with the RTX Spark, a new Arm-based processor that will power premium Windows laptops and desktops launching this fall. The company revealed the chip at Computex 2026 in Taipei, marking its first complete PC processor rather than just a graphics card. The RTX Spark features up to 20 CPU cores, 6,144 GPU cores and up to 128GB of unified memory, with a specification roughly equivalent to an RTX 5070 laptop GPU, and can reportedly host 120-billion-parameter AI agents locally. Made using TSMC's 3-nanometer process in partnership with MediaTek, the chip scales from minimal power draw to 80 watts and will appear first in machines from Microsoft, Dell, HP, Asus, Lenovo and MSI, with over 30 laptops and 10 desktops already in development. Microsoft announced the Surface Laptop Ultra as its flagship implementation, calling it "the most powerful thing we've ever made." The 15-inch laptop features a mini-LED touchscreen reaching 2,000 nits of peak HDR brightness and includes USB-C, USB-A, HDMI, full-size SD card slot and a large haptic trackpad, weighing under 4.5 pounds. Nvidia CEO Jensen Huang declared the partnership represents "the first completely re-engineered, reinvented line of PCs that has happened in 40 years," with both companies having spent years preparing Windows and its Prism emulator for Arm-based hardware. The chip targets creators, AI developers and gamers seeking thin and light machines without sacrificing performance for graphically intensive tasks like rendering 90GB 3D scenes or playing Indiana Jones and the Great Circle at 100fps at 1440p resolution. Major software developers are now supporting Windows on Arm, with Adobe optimizing Premiere and Photoshop for the platform, and game publishers including Riot Games bringing League of Legends and Valorant, Krafton releasing PUBG, and Epic already porting Fortnite. Nvidia claims all top games will run on RTX Spark through emulation, including those using anti-cheat systems like Easy Anti-Cheat, BattlEye and Denuvo. The company declined to share specific performance benchmarks or pricing, saying details will come closer to launch, but stated the initial lineup targets premium price points. Questions remain about whether the chips are manufactured in the US, Linux driver support, or potential use in gaming handhelds, with Nvidia declining to comment on each.
