Nvidia unveils RTX Spark 'superchip' for Windows PCs

Nvidia has announced the RTX Spark, a new 'superchip' designed to bring powerful on-device artificial intelligence, professional creative tools, and high-end gaming to a new generation of slim Windows laptops and compact desktop PCs.

The chip, unveiled at GTC Taipei, pairs a Blackwell RTX GPU with up to 6,144 cores and a 20-core Grace CPU, connected via Nvidia’s NVLink-C2C interconnect. It delivers up to 1 petaflop of FP4 AI performance and can be configured with up to 128 GB of unified memory.

Built in collaboration with MediaTek on a custom Arm-based design, the RTX Spark is being positioned as the hardware foundation for what Nvidia and Microsoft call the age of personal AI agents. The two companies are working together to create a secure, native Windows environment where agents can run tasks, generate content, and write code directly on a user’s primary device, according to a press release by Nvidia.

New Windows security primitives and Nvidia’s OpenShell runtime will give users control over what agents can access, while leading agent developers like OpenClaw and Nous Research plan to launch dedicated Windows apps for the platform, says Nvidia.

Beyond agent workloads, Nvidia says the RTX Spark can render 90 GB 3D scenes, edit 12K video, run 120-billion-parameter language models locally, and play AAA games at 1440p resolution with frame rates above 100 frames per second. It supports the full Nvidia software stack, including CUDA, DLSS, OptiX, and Reflex, and will power upcoming features such as DLSS 4.5 Ray Reconstruction.

As per Nvidia, Adobe is rearchitecting Photoshop and Premiere from the ground up for the new chip, promising up to twice the AI and graphics performance. Other software partners include Blackmagic Design, Blender, ComfyUI, and OTOY. On the gaming side, KRAFTON, NetEase, Remedy Entertainment, and Xbox are among the studios pledging support.

RTX Spark laptops, which can be as slim as 14 millimetres and as light as three pounds, will be available this autumn from Asus, Dell, HP, Lenovo, Microsoft Surface, and MSI, with Acer and Gigabyte models to follow. Compact desktop versions are also planned. Further details on Windows agent capabilities are expected at Microsoft Build, which runs June 2 to 3.
