Nvidia Corp. announced Nvidia Rubin CPX, a new class of GPU purpose-built for massive-context processing. 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 GB 300 NVL72 systems, as well as 100TB of fast memory and 1.7PB/s 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.
