NVIDIA at GTC 2025 announced its next-generation flagship AI GPU, the Rubin Ultra. A successor to the Blackwell Ultra unveiled this year, Rubin Ultra is slated for the second half of 2027. A single Rubin Ultra package contains four AI GPU dies joined at the hip with die-to-die bonding and a fast interconnect that enables cache coherency. The package also features a whopping 1 TB of HBM4e memory. NVIDIA is claiming a performance target of 100 petaFLOPs FP4 per package.

The company also unveiled its next-generation CPU for AI supercomputers, called simply the Vera CPU. A successor to Grace, Vera comes with 88 Arm CPU cores. These are custom high-performance cores designed by NVIDIA, and aren't carried over from the reference Arm Cortex family. The cores support SMT, giving the CPU 176 logical processors. The chip comes with a 1.8 TB/s NVLink C2C connection. Lastly, the company announced that the architecture succeeding Rubin will be codenamed Feynman, after Richard Feynman. The company is looking to debut the first silicon based on Feynman in 2028.
