With respect to consumption, it’s pretty efficient vs older traditional servers, though I know workloads like that aren’t completely fungible. Nonetheless it bears keeping in mind that a single GB200 NVL72 rack provides 1.4 ExaFLOPS of AI compute (at FP4 precision, ideal circumstances, but this is envelope math all around). So it’s power efficient, for what it is.

The compute power is also ridiculous.

Some of the reason for the high density is that you need devices physically close to each other to share such bandwidth. It’s not because we’re limited by the physical building space, because we can construct buildings all day long. Sending bits around at ultra high speed is hard and you need to keep all of the devices physically close to avoid having your interconnect costs explode.

Since you and me and everyone else will foot the elecricy bill. Energy consumption or efficiency is not a concern.
