Microsoft and Nvidia unveil Surface Laptop Ultra with RTX Spark AI chip

Microsoft announced the Surface Laptop Ultra, the first Surface device to use Nvidia’s RTX Spark superchip. The laptop combines Nvidia’s Grace‑CPU architecture with Blackwell‑GPU and AI accelerators into a single “superchip,” delivering up to 1 peta‑flop of AI compute, 128 GB of unified memory and up to 20 CPU cores.

The 15‑inch mini‑LED PixelSense Ultra display can reach 2,000 nits, and the device includes HDMI, USB‑C, USB‑A, an SD‑card slot and a large haptic touchpad. Nvidia says the platform can run on‑device AI models with up to 120 billion parameters and context windows of up to one million tokens.

Positioned as a direct answer to Apple’s Silicon‑based MacBook Pro, the Surface Laptop Ultra targets developers and professionals who need local AI processing. It will ship in the fall, with Windows 11 optimized for the RTX Spark architecture.
