Nvidia CPU leak hints at integrated gaming GPU with RTX 5070 performance

A benchmark leak has revealed that there could be a new Nvidia CPU in the works with an integrated GPU that's as powerful as an RTX 5070. It has long been rumored that Nvidia is preparing its own CPU for gamers, but the specs for this Nvidia N1X chip would make it an absolute powerhouse that would dwarf even AMD's most powerful integrated GPUs.

Nvidia is already the dominant player when it comes to the GPU market, with our best GPU guide topped by models like the RTX 5090. An Nvidia CPU with power like this, though, could upend the gaming CPU market, especially on handhelds or laptops, although there are a few reasons why it likely won't be any time soon that we see Nvidia take over the desktop PC CPU market.

The data was leaked in a recent Geekbench OpenCL test listing. It shows the Nvidia N1X name alongside specs for the chip and a score for the test run.

The Nvidia N1X specs show that it's a chip that uses the Arm CPU architecture with 20 cores split into two clusters of 10 cores each and running with a base clock speed of 4GHz.

More interesting for gamers, however, is the GPU data. The Geekbench result shows that the GPU component of this Nvidia chip has 48 streaming multiprocessors (SMs), giving it 6,144 CUDA cores. That's the exact amount of CUDA cores found in the desktop version of the Nvidia GeForce RTX 5070.

As our Nvidia GeForce RTX 5070 review shows, that's a properly powerful GPU that provides decent mid-range performance for a desktop graphics card. As part of an all-in-one SoC, those kinds of specs would easily outperform any integrated GPU on a gaming laptop or handheld.

However, the Geekbench result shows that it isn't quite ready for prime time just yet. The result shows a fairly tame 1.05GHz clock speed for the GPU, along with a score of 46,361.

The nearest comparative score for a desktop GPU, based on Geekbench's existing data, would be the Nvidia GeForce RTX 2050. Even at this level, however, it's still actively outperforming most integrated GPUs. The AMD Radeon 890M seen in the AMD Ryzen AI 9 HX 370 (used in the Asus ROG Zephyrus G14 2025 laptop), for instance, has an average Geekbench score of 37,216.

However, AMD's most powerful integrated chip does still hold a lead. The AMD Ryzen AI Max 390 uses a Radeon 8050S GPU that scores 65,818 points in the same test. You can read more about how that chip performs in our Asus ROG Flow Z13 (2025) review.

Considering this is most likely a prototype, the drop in performance versus what we know about its specs isn't entirely unexpected, as it's unlikely this chip is being pushed to full power just yet and there will no doubt be plenty of driver optimization to come.

What it does show is a statement of intent. Nvidia has been experimenting with Arm-based CPUs for some time. Earlier this year, it unveiled its GB10 system-on-a-chip (SoC) at the CES trade show for use with its Project Digits supercomputer. That chip also incorporated its recent Blackwell GPU architecture, much like this N1X chip.

Nvidia also made it clear at CES that an Nvidia CPU was in the works, but so far, one hasn't been formally announced, although rumors of an Nvidia CPU with a Blackwell GPU have made the rounds before now.

However, pairing Blackwell-level GPU performance with an Arm-based CPU intended for mobile and desktop gaming PCs could be an epoch-changing event for the gaming PC market. The Intel and AMD duopoly may be at risk if Arm-based chips like this Nvidia N1X can deliver similar, or even better, performance.

The elephant in the room, however, is that Microsoft and the gaming market has tried several times to get Arm-based systems off the ground but without much success. The much-hyped push by Qualcomm into the laptop space has had middling impact while Arm-based chips for desktop PCs still appear some way off. The sheer amount of change that is required by hardware manufacturers, software developers, businesses using PCs, and of course home users means the x86-based chips we're accustomed to still look likely to reign supreme for a long while yet.

While the performance data isn't groundbreaking, the specs alone show the potential that a gaming CPU with an integrated Nvidia Blackwell GPU could bring, and we'll be interested to see where Nvidia ends up with this N1X chip.
