- Rubin CPX advertised with 128 GB GDDR7 Memory and Advanced PCIE 6.0 Support
- Speculations are based on the fact that Rubin CPX architecture could support Nvidia’s next GeForce -Flag Ship
- Nvidia insists that ruby cpx is to AI but there are still questions about game potential
Nvidia recently introduced its Rubin CPX GPU, an AI calculation processor built for long-context workload.
It was shown as part of the Vera Rubin NVL144 CPX system and has 128 GB GDDR7 memory together with PCIE 6.0 support.
The company presented it as an engine for inference in fields such as research, development and media production of high-definition.
Nvidia RTX 6090?
Despite its AI positioning, the design has given rise to speculation as to whether Rubin CPX could also form the basis for a future GeForce graphics card.
By reporting on the new GPU, We joked that Nvidia sold us one to run games, but we weren’t the only people who saw his game potential.
On X, YouTuber High yield Noticed, “Some quick assumptions about Nvidia’s new Rubin CPX. Mid -equal to GB202 with some obvious changes in the GPCs. Looks like it has full raster units (full GPU) with up to 256 rops. Could this be RTX 6090? (Although ruby should only be AI).”
Videocardz was fascinated by High yield‘s proposal, which agrees that Rubin CPX, displayed during the AI technology conference, appears to include elements that are not typically needed in AI Compute processors.
These include raster devices, display engines and a complete set of rops, all of which are important in gaming GPUs.
The site noted that Rubin CPX could integrate 16 graphics treatment clusters, each with 6 texture treatment clusters, a total of 192 SMS.
A game version after the Blackwell pattern of 8 TPCs per GPC could expand this to 256 SMS.
Videocardz also pointed out that such a configuration may support 256 rops, a 512-bit GDDR7 interface and close to 28,000 cuda kernels.
Compared to GeForce RTX 5090’s GB202 GPU, with 192 SMS and 176 rops, this would offer a 28 percent increase in grains. This scale would place any resulting RTX 6090 among the largest consumer GPUs ever built.
Rubin CPX was shown solely as an artistic reproduction rather than a confirmed Die shot, which is hardly surprising considering that it is not expected to arrive until late in next year.
Nvidia has described Rubin CPX strictly as an AI-focused product, and if there is any hidden GeForce connection, it will be a wait before we know it for sure.
