Nvidia’s RTX Spark N1X processor is now available in Windows laptops from six different manufacturers, and The Verge reports testing four of them. The chip is an Arm-based system-on-chip aimed at laptops and small desktops, positioned to compete with offerings from Apple, Intel, AMD, and Qualcomm. It combines a large number of cores with Nvidia RTX Blackwell graphics and enough power and unified memory to run sizable AI models locally.
The flagship implementation is Microsoft’s Surface Laptop Ultra, configured with 128GB of unified memory and reviewed by The Verge’s Tom Warren. A 64GB version of an Asus laptop was also among the devices tested.
Why it matters
An Arm-based SoC with substantial unified memory and dedicated graphics could expand the ability to run sizable AI models directly on consumer laptops, reducing reliance on cloud infrastructure.
Who should care
Buyers evaluating AI-capable Windows laptops, and developers or users interested in running local AI models on-device, will find the testing relevant given the range of manufacturers and memory configurations.
