The nature of NVIDIA N1/N1x SoCs still remain a bit of a mystery at this point, but one recent Geekbench entry has revealed and confirmed some information on what the more powerful model, the N1x, may look like. Essentially, it matches the specs of its sister model, the GB10 Superchip, which found its way in specialized AI mini-PCs.
NVIDIA N1x Spotted
First, this Geekbench entry confirms the N1x will feature 20 CPU cores, split into two 10-core clusters. Going by GB10’s specs, we can assume the performance cluster features 10 Arm Cortex-X925 cores operating at 4GHz, while the efficiency cluster is 10 Arm Cortex-A725 focusing on background tasks for better power efficiency.
As for the GPU, the entry lists 48 “Compute Units”, which is technically referred as Streaming Multiprocessors (SMs) in NVIDIA’s parlance. We know this is Blackwell-based, so each SM equates 128 CUDA cores – hence, 48 SMs indicate a total of 6,144 CUDA cores, once again identical to GB10, and matching the numbers of the RTX 5070 Ti desktop GPU. Its video memory will rely on the 128GB unified memory, so as far as gaming is concerned, VRAM capacity won’t be an issue.
Naturally, we can’t judge the chip’s performance from this benchmark entry right now, given that early samples always have optimization issues, and in some cases this is done to avoid revealing the chip’s potential until official announcement. Speaking of which, the reveal for this lineup was reportedly delayed well into 2026 due to hardware flaws, warranting a chip redesign.
Pokdepinion: Safe to say this will be rivaling the likes of AMD Ryzen AI Max and Apple M3 Ultra SoCs.
