Are they? I'm seeing figures around 80 watts at rest, and 150 when exercising. The brain itself only uses about 20 watts [1]. That's 1/35 of a single H100's power consumption (700 watts - which doesn't even take into account the energy required to cool the data center, the humans who build and maintain it, ...).

- mlyle 2y agoThe PUE of humans for that 80 watts is terrible, though. Ridiculous multiples of additional energy needed to convert solar power to a form of a energy that they can use, and even the manufacturing lifecycle and transport of humans to the datacenter is energy inefficient.
