Nvidia CEO Jensen Huang today unveiled the RTX Spark Superchip, the company's first-ever Arm-based PC processor, at Computex 2026. The chip will power a new generation of Windows laptops and desktops from major OEMs including Dell, HP, Microsoft, and ASUS. Microsoft simultaneously launched the Surface Laptop Ultra, the first flagship Surface to feature Nvidia silicon.
The move marks a strategic pivot for Nvidia, which has dominated the AI accelerator market but never designed a full system-on-chip for consumer PCs. By combining its own Arm CPU with a powerful Blackwell GPU, the company aims to transform Windows into what it calls an "agentic AI" operating system — capable of running sophisticated local AI models without relying on cloud services.
The RTX Spark features a 20-core Arm CPU, a 6144-CUDA-core Blackwell GPU, and up to 128GB of unified memory, according to Tom's Hardware. Nvidia claims the chip delivers 1 petaflop of AI computing performance, placing it in direct competition with Apple's M-series and Qualcomm's Snapdragon X chips. Unified memory enables the CPU and GPU to access the same pool without copying data, a key advantage for AI workloads.
The Surface Laptop Ultra, arriving this fall, will sport a 15-inch mini-LED touchscreen and up to 128GB of unified memory, positioning it as a premium device for developers and AI researchers. For Nvidia, entering the PC market opens a massive revenue stream beyond its datacenter business. However, the company faces steep competition from Intel, AMD, and Apple, each with years of Windows and Mac ecosystem experience.
Some analysts question whether Windows software is ready to fully leverage local AI processing at scale. Microsoft's previous attempts at Arm-based Surface devices have struggled with application compatibility and performance, and Nvidia's chip faces similar hurdles in a market dominated by x86 architecture.
