Nvidia is entering the PC processor market. Nvidia CEO Jensen Huang (젠슨 황) on Sunday unveiled an ARM-based processor called N1X, developed with Microsoft, in a keynote speech at Computex 2026 in Taiwan.

N1X will be installed in the new RTX Spark superchip and will be released this autumn in new Windows PC lineups from Microsoft, Dell, HP, Asus, Lenovo and MSI. Nvidia plans to apply the chip to more than 30 laptops and 10 desktops.

RTX Spark combines Nvidia's Blackwell GPU and an ARM-based 20-core CPU designed by Taiwan's MediaTek using NVLink C2C, and adds 128 GB of unified memory. It has 6,144 CUDA cores and up to 300 GB per second of memory bandwidth, delivering 1 petaflop of AI performance. It can handle 120 billion-parameter models and tasks up to 1 million tokens in length. It will be manufactured using TSMC's 3-nanometre process in Taiwan.

Huang said, "This reinvention of the computer is as big an event as the mobile phone being reborn as the smartphone," and stressed it was a "PC lineup completely redesigned for the first time in 40 years." He added, "Microsoft and Nvidia will reinvent the PC."

ARM-based chips are rapidly threatening the x86 camp led by Intel and AMD. Huang predicted the CPU market would grow to $200 billion. The first RTX Spark laptop will be a thin and light model about 14 mm thick, targeting creators, AI developers and gamers. Its performance is at a similar level to Nvidia's RTX 5070 laptop GPU, and detailed metrics will be disclosed at the time of its autumn release.

Huang also said mass production has begun in earnest for the Vera CPU for data centres. Initial customers include Anthropic, OpenAI, SpaceX's xAI, Dell, Oracle and CoreWeave.
