Nvidia RTX Spark Superchip Launches at Computex 2026, Targeting AI-Powered Windows Laptops and Desktops

Nvidia is expanding beyond data center dominance into personal computing. At Computex in Taipei, CEO Jensen Huang unveiled the new N1X processor, incorporated into the RTX Spark superchip, debuting this fall in Windows PCs from Microsoft, Dell, HP, ASUS, Lenovo, and MSI. The chip packs up to 20 Arm CPU cores, a Blackwell GPU with 6,144 CUDA cores, 128GB of LPDDR5X RAM, and up to 300 GB/s of memory bandwidth — enough to run 120-billion-parameter AI models and context lengths stretching to a million tokens. Huang called it as transformative as the smartphone revolution, pointing to agentic AI running across all new machines. First laptops will be as thin as 14 millimeters and targeted at creators, AI developers, and gamers seeking thin, portable form factors. Performance is described as "roughly equivalent" to Nvidia's RTX 5070 laptop GPU. Confirmed devices include the Microsoft Surface Laptop Ultra and Dell XPS 16.
