I've heard 5GW touted as the capacity (so like 120GWH per day if flat loaded at 100%). However that is clearly B.S as I've also heard 2GW and another much more sensible number

Just to give perspective 5GW would power about 10 Million H100s or about 5 million G200. Completely farcical, won't happen.

Total rewrite of my previous reply:

There's a 7-million-sqft data center near Reno that claims 650MW capacity. Zuck says his will be 4 million sqft. So that doesn't really get us to 5GW unless we're going vertical.

To be fair, datacenter power density has skyrocketed over time: https://www.ramboll.com/en-us/insights/decarbonise-for-net-z...

These are being built at the same time, so any trends over time are not in play.

If they averaged only 60KW per rack that would be about 1.7Million sqft of 'white floor space' or about 3-4 million sqft gross building size.
