Microsoft Unveils Surface Laptop Ultra Powered by Nvidia RTX Spark

Microsoft announced the 15-inch Surface Laptop Ultra, its most powerful Surface yet, built around Nvidia’s RTX Spark “superchip” for Windows 11 on Arm. The RTX Spark chip can provide up to 20 CPU cores, 6,144 GPU cores and 128GB of unified memory (with some configs as low as 16GB), and the laptop promises all-day battery life, RTX‑level graphics around the 5070 tier, and up to 1 petaflop of AI compute. It features a 15-inch mini‑LED display with up to 2,000 nits of peak HDR brightness, the largest haptic trackpad Microsoft has shipped, and ports including USB-C, USB‑A, HDMI and a full-size SD card slot. Weight is listed under 4.5 pounds. Final specs and pricing remain unannounced. Microsoft also positions RTX Spark as part of a broader push with Nvidia and other OEMs to bring Windows on Arm to premium laptops, with several partner devices teased for this fall.
