This is very important, filling racks with GPU's instead of CPU's is vastly more power hungry (and hence will generate a lot more heat). Vera Rubin is 1800-2300W, mind boggling, these data centers even have new power architectures coming.

And I know what people will say, Vera Rubin is vastly more efficient, but that only matters if you have saturated your needs, it's meaningless if you need that capacity, and I'm sure it will run pretty much at a 100% 24/7.
