It's a ridiculous amount claimed for sure. If its 2 kW per it's around 5 million, and 1 to 2 kW is definitely the right ballpark at a system level.

The NVL72 is 72 chips is 120 kW total for the rack. If you throw in ~25 kW for cooling its pretty much exactly 2 kW each.

So each 2KW component is like a top-shelf space heater which the smart money never did want to run unless it was quite cold outside.
