Context Before
Source: Nvidia VR NVL72 Component BoM and Power Budget Model ↗
Evidence
The design retains the same features as Spectrum-5, with 8 IO chiplets surrounding the main switch die
Context After
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.
② Atomic Claim
