NVIDIA N1X PC Processor Features 20 Arm CPU Cores and 48 iGPU Streaming Multiprocessors
NVIDIA is looking to hit the PC processor market with shock and awe, suggests the CPU core counts and iGPU CU counts. Having seen the success of Qualcomm in this market, NVIDIA is designing its new N1X PC processor in anticipation of Microsoft opening up the Windows 11 Arm Copilot+ AI PC ecosystem, letting in new players such as NVIDIA and MediaTek. A new Geekbench online database submission sheds light on what is under the hood.
Geekbench is able to detect the number of CPU cores and GPU OpenCL compute units it is able to address. A user with access to an N1X test machine ran Geekbench 6.4.0, and the benchmark yielded a score of 46361 points in the OpenCL test. The chip is detected having 20 CPU cores, and exposes 48 compute units (OpenCL terminology) to the GPU compute benchmark. The N1X is expected to implement a heterogenous multicore CPU complex, and while it has 20 cores, these are not all the same. The processor is expected to pack a powerful iGPU based on the Blackwell graphics architecture, with 48 SM (streaming multiprocessors), The idea behind such a chip would be to compute with Apple's M-Pro and M-Max series SoCs powering its latest MacBook Pros, as well as x86-based PC chips such as the Ryzen AI Max "Strix Halo." 48 Blackwell streaming multiprocessors is identical to that of the desktop GeForce RTX 5070, but the iGPU, making it possibly the fastest iGPU at launch.

If this thing is made available in a laptop/big tablet for $800 and out-performs an Intel or AMD based equivalent twice its price, then I'll eat my hat.
This is likely to be another Q1Elite fiasco, attempting to charge a lot more for fewer features, more AI that only two or three care about, and a bit more battery life.
And has Qualcomm actually had much success in this market? There was a lot of excitement around SD-X leading up to launch, but I thought they weren't selling all that significantly? The NVIDIA name could help, or it could be a big let down if people buy this thinking it's going to be more capable than it actually is.
ARM designs have shown remarkable battery life so far. As long as Nv keeps this under control they'll be able to develop a solid chip indeed.
