The N1X is an Arm-based system-on-chip with 20 CPU cores, 6,144 CUDA cores and Nvidia's Blackwell graphics, plus enough unified memory to run sizable local AI models. The five laptops tested spanned the range: a 128GB Surface Laptop Ultra, 64GB and 128GB Asus ProArt P16 machines, a 64GB Lenovo Yoga 9n and a 32GB HP OmniBook Ultra. Prices run from $3,199.99 for the HP up to $6,999.99 for the top Asus, and even the cheaper 18-core N1X configs start at $2,599.99.

On software, the picture is brighter than Arm sceptics might expect. Years of development pushed by Qualcomm's Snapdragon X chips mean many apps now run natively, and x86 software works through Microsoft's Prism emulation. One writer made an RTX Spark machine a daily driver with a full slate of work and personal apps and never had to think about which architecture an app used, though there were occasional hiccups: slow-loading apps, dark mode preferences ignored and notes briefly vanishing in Evernote.

Gaming is where the chip both shines and stumbles. There are still few native Arm games, but the GPU pushes through the emulation layer well enough that medium settings at 1440p with DLSS performance mode delivered a stable 60fps in most titles tested, including Black Myth: Wukong at an average 70fps and Cyberpunk 2077 at 66fps. That is short of a dedicated gaming laptop, but the testers noted the CPU may hold some games back. That CPU caveat has an architectural explanation: ServeTheHome's launch overview notes the N1X is the consumer name for Nvidia's GB10 chip, developed with MediaTek on Arm's 2024 Cortex core designs and tuned for multi-threaded rather than single-threaded performance, which puts it slightly behind the curve on CPU technology.
