Context Before

At CES 2026, Nvidia officially announced in detail all 6 Rubin platform products: the Rubin GPU, Vera CPU, NVLink 6 Switch, ConnectX-9, BlueField-4, and Spectrum-6. VR NVL72 is the second generation of Nvidia’s rack scale Oberon architecture that takes the stage. With competition catching up on rack scale game, Trainium 3 in the Gen2 UltraServer, AMD MI450X Helios Racks, and Google’s TPU which was at rack scale even before GB200, Nvidia answers with “extreme co-design” supremacy. With extreme co-design, Nvidia takes rack scale integration to the next level. Rack system becomes a unit of compute, a single distributed accelerator, and Nvidia designs the system.

Evidence

For the Vera Rubin platform, Nvidia is asserting even more control over the system and rack level design.

Context After

Rack scale integration and assembly have become more challenging, as every component is being pushed to the limit, whilst also optimizing for cost efficiency. VR NVL72 has a much more holistic design with a modular approach compared to Grace Blackwell for the purpose of integration efficiency and throughput.
