Nvidia unveils Rubin CPX class of GPUs

At the AI Infra Summit, Nvidia (NVDA) announced Rubin CPX, which it calls “a new class of GPU purpose-built for massive-context processing.” The company stated: “This enables AI systems to handle million-token software coding and generative video with groundbreaking speed and efficiency. Rubin CPX works hand in hand with NVIDIA Vera CPUs and Rubin GPUs inside the new NVIDIA Vera Rubin NVL144 CPX platform. This integrated NVIDIA MGX system packs 8 exaflops of AI compute to provide 7.5x more AI performance than NVIDIA GB300 NVL72 systems, as well as 100TB of fast memory and 1.7 petabytes per second of memory bandwidth in a single rack. A dedicated Rubin CPX compute tray will also be offered for customers looking to reuse existing Vera Rubin 144 systems.” Jensen Huang, founder and CEO of Nvidia, added: “The Vera Rubin platform will mark another leap in the frontier of AI computing – introducing both the next-generation Rubin GPU and a new category of processors called CPX. Just as RTX revolutionized graphics and physical AI, Rubin CPX is the first CUDA GPU purpose-built for massive-context AI, where models reason across millions of tokens of knowledge at once.”
