Nvidia has announced the Rubin GPU architecture, the successor to Blackwell, at Computex 2024. The Rubin GPUs are expected to launch in 2026, supporting 8-Hi HBM4 stacks, and will be succeeded by Rubin Ultra GPUs, supporting 12-Hi HBM4 stacks. Alongside the GPU announcement, Nvidia also revealed a powerful new CPU called Vera.
The Rubin architecture will debut with support for 8-Hi HBM4 stacks. The first Rubin GPUs, likely to be named R100 CPUs, are expected to enter mass production in late 2025, aligning with Nvidia’s official announcement for an early 2026 debut. Rubin Ultra GPUs, compatible with 12-Hi HBM4 stacks, are set to follow in 2027, adhering to Nvidia’s one-year rhythm for data center releases.
The Vera CPU will feature on a new Vera Rubin accelerator board, alongside one of the Rubin GPUs, and is set to replace current offerings like the Grace Hopper super chip. Details about the Vera CPU are currently limited, but it’s expected to deliver various optimizations to the Arm CPU cores and/or a bolstered overall configuration.
Other highlighted features of the Rubin platform include the speedy NVLink 6 Switch performance of up to 3,600 GB/s, and a touted CX9 SuperNIC component offering up to 1,600 GB/s. As we wait for the next-gen Blackwell GPUs, the details on Rubin remain limited. However, the Blackwell architecture parts are expected to debut as B100 and B200 GPUs starting later this year.
