Nvidia and Microsoft unveil RTX Spark AI‑powered Windows PCs

Nvidia announced, together with Microsoft, a new line of Windows laptops, desktops and workstations powered by the RTX Spark ARM‑based CPU‑GPU chip. The launch was previewed at Computex in Taiwan and at the Build developer conference in San Francisco. The RTX Spark processor combines a Grace‑CPU with 20 ARM cores (ten Cortex‑X9 and ten Cortex‑A7) and a Blackwell GPU featuring 6,144 CUDA/Tensor cores, delivering up to one petaflop of AI performance and supporting up to 128 GB of LPDDR5X memory. Nvidia highlighted use cases such as 4K AI‑generated video, 12K video, large 3D scenes, and AAA gaming at 1440p with 100 fps. The platform ships with a Windows‑on‑ARM layer that schedules workloads across all cores and includes an OpenShell runtime for secure local AI agents. Early devices from ASUS, Dell, HP, Lenovo, MSI and Microsoft’s Surface Laptop Ultra are slated for release in the autumn. Jensen Huang said the PC is “being reinvented” with this new architecture, aiming to create a segment for personal‑AI agents and high‑performance creative work.
