Evidence
While for NVL36*2, each rack has a max TDP of ~67kW while both rack pairs take in ~132kW.
Context After
Compute Tray Diagrams & Cabling
The heart of the GB200 NVL72/NVL36x2 is the Bianca board. The Bianca board contains two Blackwell B200 GPUs and a single Grace CPU. The ratio between CPU and GPU is now 1:2 on a board compared to GH200, which is a 1:1 ratio. Most of the customers that evaluated GH200 have told Nvidia that it was too expensive as 1:1 CPU ratio was too much for their workloads. This is one of the main reasons why GH200 shipped in such low volumes compared to HGX H100 (2 x86 CPUs, 8 H100 GPUs). For Blackwell, GB200 volume is way up relatively and there will be crossover in unit shipments versus HGX Blackwell B100/B200. ↗
