Nvidia and Microsoft Launch RTX Spark: Ushering in a New Generation of Windows on Arm PCs
On June 1 at Computex 2026 in Taipei, Nvidia CEO Jensen Huang announced the company’s pioneering venture into the PC processor market. He introduced the RTX Spark superchip, a revolutionary combination of Arm-based computing and potent AI capabilities. This groundbreaking N1X processor, a collaborative effort with Microsoft and MediaTek, boasts 20 Arm CPU cores and a Blackwell-architecture GPU with 6,144 CUDA cores. This matches the performance of a desktop RTX 5070.
The RTX Spark platform offers an impressive 1 petaflop of AI computing power and supports up to 128GB of unified memory. This allows for dynamic allocation between the CPU and GPU. Come this fall, major PC manufacturers such as Dell, HP, ASUS, Lenovo, and MSI will be launching laptops powered by RTX Spark. Leading the pack is Microsoft’s new Surface Laptop Ultra, touted as the most powerful Surface device ever built.
This venture marks Nvidia’s first significant challenge to the dominance of Intel, AMD, and Qualcomm in the PC processor market. It brings full CUDA support and desktop-class GPU performance to Windows on Arm devices for the first time. Huang likens this move to a reinvention of the PC, comparing it to the smartphone revolution.
