Alleged Nvidia N1X and N1 specs for Windows 11 laptops leak early, here are the details

Microsoft, Nvidia could soon unveil Arm-based Windows 11 laptops using N1/N1X chips. Here are the leaked specs of these new processors.

Earlier this week Microsoft teased that a "new era of PC" was going to be upon us very soon. The company quickly ended any speculation regarding a possible next gen OS like "Windows 12" though we soon started to get an idea of what it was when Nvidia also put up the same teaser post on its social media handles.

Following this, we began getting more concrete evidence of new Windows on Arm laptops that would be powered by Nvidia CPU, specifically the company's new N1X and N1 processors. These would include new Surface devices as well as traditional Windows laptops from the likes of OEMs like Dell, Lenovo and more.

Although we had a rough idea about the might of the Nvidia N1X series, a new report from VideoCardz has revealed the purported detailed specifications of the SKUs right ahead of the launch.

According to the leak, the flagship N1X configuration will feature a 10+10 core CPU setup based on Arm's Cortex-X925 and Cortex-A725 designs, paired with a 48 SM (Steaming Multiprocessor) Blackwell GPU packing 6144 CUDA cores. Nvidia is also said to be preparing a slightly cut-down 9+9 core variant with 40 SMs, bringing the CUDA core count down to 5120.

Simply by SM/CUDA core count, the full N1X is about equivalent to the RTX 5070 while the cut-down SKU is faster than the 5060 Ti. What could be the limiting factor though is the memory bandwidth.

Interestingly, both N1X models are reportedly designed for a 45W to 80W power envelope, putting them firmly in premium performance laptop territory. The chips are also said to support up to 128GB of LPDDR5X memory through a 16-channel memory interface, alongside 12 PCIe 5.0 lanes and five PCIe 4.0 lanes for storage and expansion.

The standard N1 lineup appears to be aimed at more mainstream devices. One variant is tipped to feature a 12-core CPU paired with a 20 SM GPU containing 2560 CUDA cores, while another could ship with a 10-core CPU and a 16 SM graphics configuration for 2048 CUDA cores. These chips are reportedly configured for lower power operation between 18W and 45W, while supporting between 8GB and 64GB of LPDDR5X memory.

Storage support is also said to differ between the two families. While N1X systems are expected to accommodate up to three M.2 SSDs, the more affordable N1 platform may be limited to two drives. If accurate, the specifications suggest Nvidia is targeting everything from thin-and-light AI PCs to high-performance creator and gaming laptops with its first major Windows-on-Arm push.

The report further claims that the full-fat N1X configuration mirrors the GB10 Superchip found inside Nvidia's DGX Spark platform, something that aligns with previous rumors surrounding the company's Arm-based PC ambitions. With the official announcement expected imminently, it remains to be seen which of these configurations will actually make it to retail devices and how they will stack up against offerings from Qualcomm, AMD and Intel.
