notes

Direct PDF fetch (doc 4169750, Oct 25). Max TDP 'Configurable up to 1,400 W' for GB300 NVL72 per Blackwell Ultra GPU and 'Configurable up to 1,100 W' for HGX B300. Also states GB300 NVL72 is a 'fully liquid-cooled, rack-scale architecture'. Notably normalizes AI-factory output per MEGAWATT (TPS in a 1 MW AI factory), which is the vendor's own acknowledgement that power is the binding unit.
