Rubin Oberon Rack: NVL72 not NVL144 nor NVL36

Since the announcement of GB200 at Nvidia GTC 2024, the concept of an AI server system has shifted from a chassis to a rack scale system. In our GB200 article , we discussed the evolution of Nvidia AI server form factor from HGX (8 GPU per node) to Oberon (NVL72 rack scale). While the HGX form factor still exists, the majority of Nvidia’s Blackwell GPUs are integrated in the Oberon form factor. Rubin will also be offered in both HGX and Oberon systems.

Evidence

The key difference between the Blackwell and Rubin Oberon architecture is the number of SKUs offered to customers

Context After

Unlike Blackwell, Rubin is only offered in the VR NVL72 SKU. The set up is very similar to that of GB200/GB300 NVL72. Each VR NVL72 system consists of:
