Lenovo has unintentionally confirmed it is building laptops around Nvidia’s unannounced N1X chip. The slip came from Lenovo’s own ADFS authentication system, where an internal login page referenced an “Nvidia N1x Portal.” VideoCardz was the first to spot it.
Earlier leaks from Lenovo support pages added more detail. Several unreleased Lenovo systems appeared with N1 and N1X labels attached, including one listed as the Legion 7 15N1X11. That model name points directly to a Legion 7 gaming laptop built on the N1X chip.
What is NVIDIA N1X?
Based on leaks, the N1X is an ARM-based chip from Nvidia that puts a 20-core CPU and a Blackwell GPU together in a single package. The CPU splits into 10 performance cores and 10 efficiency cores.
The GPU side carries 6,144 CUDA cores, which matches the core count on the desktop RTX 5070. The chip is built on a 3nm process and supports up to 128GB of LPDDR5X memory.

The N1X is likely the same chip inside Nvidia’s DGX Spark compact AI computer, which runs at 120W. A laptop version would almost certainly ship at a lower wattage to manage heat and battery life, so you should expect some performance reduction compared to the full desktop configuration.
Even with that adjustment, it would still sit well above anything currently shipping in a Windows ARM laptop.
What Changes the Nvidia N1X Chip Might Bring to Windows Gaming Laptops
If the chip performs anywhere close to what the specs suggest, a Windows ARM laptop could, for the first time, handle gaming, video editing, and AI workloads without a separate graphics card. That would be a significant shift for the platform.

The main question is software. Windows on ARM has improved over the past couple of years, but game compatibility and driver support still have gaps. How well Nvidia addresses those issues will determine whether the Legion 7 N1X becomes a practical choice or just an impressive spec sheet.
For anyone who has been waiting for a Windows ARM laptop that can genuinely compete with Apple’s MacBook Pro lineup, the N1X-powered Legion 7 looks like the most credible attempt yet.
