Computex 2026: NVIDIA Unveils RTX Spark AI Superchip for Next-Gen Windows PCs

NVIDIA has announced RTX Spark, a new AI-focused superchip designed to bring advanced on-device artificial intelligence, content creation, and gaming capabilities to Windows PCs. Developed in collaboration with Microsoft and MediaTek, RTX Spark combines NVIDIA’s Blackwell GPU architecture with a custom Grace CPU to create what the company describes as a new category of personal AI computers.

At the heart of RTX Spark is an NVIDIA Blackwell RTX GPU featuring 6,144 CUDA cores and fifth-generation Tensor Cores with FP4 precision. The GPU is connected to a 20-core Grace CPU through NVIDIA’s NVLink-C2C interconnect. NVIDIA claims the platform can deliver up to one petaflop of AI computing performance and support up to 128GB of unified memory.

A major focus of RTX Spark is enabling secure, private AI agents that run directly on users’ devices. NVIDIA and Microsoft are introducing new Windows security primitives alongside NVIDIA OpenShell, a runtime environment that allows users to control how AI agents access data, interact with applications, and communicate with cloud-based models. The system is designed to support emerging AI assistants capable of managing workflows, searching local files, generating media, and automating tasks across applications.

Several AI developers have already pledged support for the platform. OpenClaw Foundation and Nous Research, the creators of Hermes Agent, confirmed they are adopting the Windows security framework and NVIDIA OpenShell for their next-generation agent applications.

Beyond AI, RTX Spark is positioned as a powerful platform for creators and gamers. NVIDIA says the chip can handle 90GB 3D scenes, edit 12K video, run 120-billion-parameter language models, and deliver ray-traced gaming at 1440p with frame rates exceeding 100fps. It will also support upcoming technologies such as DLSS 4.5 Ray Reconstruction and RTX Video with 4x Frame Generation.

The ecosystem around RTX Spark is already growing. Software companies including Adobe, Blackmagic Design, Blender, CapCut, ComfyUI and OTOY have committed support. On the gaming side, developers including KRAFTON, NetEase, Remedy Entertainment, Riot Games and Xbox are also embracing the platform.

With backing from Microsoft, major software vendors, game developers, and AI-agent creators, RTX Spark represents NVIDIA’s most ambitious attempt yet to bring powerful AI processing directly to everyday PCs.
