Nvidia Rubin CPX die shot reveals graphics-specific hardware blocks not needed for an AI GPU — Rubin CPX may form the foundation of next-gen RTX 6090

Nvidia unveiled the Rubin CPX GPU earlier this week at the AI Technology Conference as part of its next-generation data center portfolio, which is designed to accelerate inference workloads. Rubin CPX, in particular, focuses on compute rather than bandwidth to form the other part of a “disaggregated” AI architecture that will kick off with Vera Rubin next year. Today, however, a closer look at its silicon suggests there might be more to this AI accelerator than Nvidia has let on, with some speculating…
