NVIDIA RTX Spark: ARM Chip with Blackwell GPU — The New AI PC Era Begins at Computex 2026
At Computex 2026 in Taipei, NVIDIA and Microsoft announced the RTX Spark platform — an ARM superchip combining 20 Grace CPU cores with a Blackwell-class GPU. It's NVIDIA's first serious push into the ARM-PC segment.
RTX Spark packs 20 Grace ARM CPU cores, a Blackwell-class GPU with 6,144 CUDA cores, and up to 128GB of LPDDR5x unified memory running at 300 GB/s. Declared AI performance is 1 petaflop (FP4).
AI-First Platform
The core idea behind RTX Spark is running personal AI agents directly on-device. The platform can run 120B-parameter LLMs locally with up to 1 million token context, render 90GB+ 3D scenes, and edit 12K video — all on a portable machine.
NVIDIA claims RTX Spark delivers RTX 5070-level gaming performance, capable of running AAA games at 1440p above 100 FPS.
Partners and Devices
RTX Spark devices were announced from eight OEMs: ASUS, Dell, HP, Lenovo, Microsoft (Surface Laptop Ultra), MSI, Acer, and GIGABYTE. More than 30 laptops and 10 compact desktops are planned, with first units arriving in Fall 2026.
Microsoft already revealed the Surface Laptop Ultra — a 15-inch laptop with a 2880×1920 Mini LED display and 2,000-nit peak brightness.
Three-Generation Roadmap
NVIDIA also revealed a roadmap: RTX Spark will be followed by the Rubin platform (with LPDDR6 memory) and then Rosa Feynman, signaling a long-term commitment to the ARM-PC segment.
