NVIDIA’s GeForce RTX 6090 Design, Speculation Suggests
NVIDIA’s recently unveiled Rubin CPX AI processor is already sparking intense speculation within the tech community, with experts suggesting its architecture could provide a blueprint for the company’s next-generation gaming graphics cards, potentially the GeForce RTX 6090.
Introduced at the AI Technology Conference as part of a data center solution, the Rubin CPX is marketed as a pure compute processor. However, a detailed analysis of the published die render by industry observers, including YouTuber High Yield, reveals it contains components that are unnecessary for AI tasks but essential for gaming: raster units, display engines, and a full set of ROPs (Render Output Units).
This discovery has led to the compelling theory that the Rubin CPX architecture could be repurposed for consumer graphics. Based on the render, the chip appears to integrate 16 Graphics Processing Clusters (GPCs). If it follows the architectural shift seen in Blackwell (increasing Texture Processing Clusters per GPC from 6 to 8), a gaming variant could feature a massive 256 Streaming Multiprocessors (SMs).
Some quick assumptions about @Nvidia's new Rubin CPX. Quiet similar to GB202, with some obvious changes to the GPCs. Looks like it has full raster units (full GPU) with up to 256 ROPs. Could this be the RTX 6090? (even though Rubin was supposed to be AI only) pic.twitter.com/EBRYpH39VB

This theoretical “GR202” GPU would represent a significant leap over the current flagship, the RTX 5090’s GB202 with 192 SMs. Estimates suggest an RTX 6090 based on this design could ship with approximately 28,000 CUDA cores—a roughly 28% increase in core count. It is also speculated to support a 512-bit memory bus for next-gen GDDR7 memory, PCIe 6.0, and over 2 TB/s of memory bandwidth.

It is crucial to note that the Rubin CPX is currently only an artistic render, and NVIDIA has announced it for a late 2026 release. The company often uses a unified architecture that scales from data center to consumer products, making this speculation plausible. However, until an official announcement is made, the existence of an RTX 6090 based on Rubin remains an exciting, educated guess from the tech community.
