Nvidia has unveiled its new RTX Spark CPU at Computex 2026, marking a bold push into the $200 billion high-performance CPU market. Dubbed a 'superchip,' the RTX Spark delivers 1-petaflop performance and is designed to run AI agents like OpenClaw and Hermes Agent securely and locally on Windows PCs. Major manufacturers including Microsoft, Dell, HP, Lenovo, and ASUS will release AI-powered systems this fall, with some models expected to mirror the capabilities of Nvidia’s $4,800 DGX Spark developer machine.

The new chips are built to support local execution of large language models, powered by Nvidia’s CUDA software and enhanced by secure sandboxes developed jointly with Microsoft. Over 100 software partners, including Adobe, Blender, Riot Games, and Xbox, have signed on to support the platform. Nvidia CEO Jensen Huang envisions a future where users simply ask their PC to perform tasks, eliminating the need for traditional app navigation.

While Nvidia’s earlier ARM-based Windows efforts failed — notably the $900 million Microsoft Surface RT write-off — this new generation is significantly more powerful. Microsoft is branding its top model as the Surface Laptop Ultra, calling it the most powerful Surface ever built. However, pricing details remain scarce, and it's unclear whether these systems will compete with affordable options like the Mac Mini or dominate the premium segment.
