When he’s not working, you’ll find him bending tubes for his ever-evolving custom water-loop gaming rig or benchmarking the latest CPUs and GPUs just for fun.
bit_user The article said: For those out of the loop, for years we've heard about the N1 silicon: purported to be an RTX 5070-class GPU featuring 6,144 CUDA cores, combined with 20 ARM cores built on the Grace architecture. Co-developed with MediaTek, the N1 is actually what powers the GB10 Superchip inside the DGX Spark, as confirmed by Jensen Huang himself. So, the hardware definitely does exist, but it's only served as a blueprint for Nvidia's AI efforts instead of getting a mainstream desktop (N1) or mobile (N1X) release. So, I've tried to follow the rumors and it's not clear to me whether the GPU die in N1(X) is the same as GB10, or just the CPU portion. As explained here, the GB10 is actually comprised of two logic dies: the CPU cores (and SoC) + GPU die: Source: https://www.chiplog.io/p/analysis-of-nvidia-dgx-sparks-gb10 Note that the block diagram isn't to scale. In the GB10, the two dies are closer to equal in size. Anyway, that explains why Nvidia calls it a "superchip" – because it consists of two distinct chiplets. You'll see the same terminology being used to describe a Grace CPU paired 1:1 with a Hopper or Blackwell GPU. What we know is that the N1(X) features the same 20-core configuration and we've heard that it's the same silicon, but I don't know if any specs have leaked about the N1(X) GPU portion. Anyway, if you think about it, it would make a lot of sense for them to differentiate by swapping in different GPU tiles. Reply
bit_user The article said: If launched, the N1 lineup would mark Nvidia's grand return to the conventional CPU segment in more than a decade, since the Tegra X1 last powered the Nintendo Switch. Uh, what are you talking about?? Have you heard of the Switch 2? You know Nvidia makes that SoC, as well, right? They have an even newer SoC than the one in Switch 2! These are primarily aimed at embedded applications, like robotics and self-driving cars, but they're fully capable of being used in client devices. https://en.wikipedia.org/wiki/Tegra#Orin What's notable about the GB10 and N1(X) is that it's actually a partnership with MediaTek, rather than Nvidia running the whole show on its own. It's a little hard to see what Nvidia gets out of sharing the glory with MediaTek, but then I guess it does save Nvidia the burden of having to support the SoC on Windows. Also, as noted in the article, expect to see a similar integration model between Nvidia iGPUs and future Intel laptop CPUs. Reply

This link is in the article where it mentions the configuration and while it's not impossible to fake Geekbench submissions it doesn't seem particularly likely. https://www.tomshardware.com/pc-components/gpus/nvidia-n1x-soc-leaks-with-the-same-number-of-cuda-cores-as-an-rtx-5070-n1x-specs-align-with-the-gb10-superchip I do agree that it would make sense to have different GPU die available and maybe that's what the N1 would be.
