The largest GPU clusters and AI supercomputers

xAI Colossus Memphis Phase 3 leads with 275.8K H100e, ahead of xAI Colossus Memphis Phase 2 (200K H100e) and Meta 100k (100K H100e).

The top five account for 56% of the 1.4M H100e tracked across this ranking.

A cluster is not the same thing as a data center: several clusters can share a site, and the largest sites are built in phases that each rank separately here. Where a record is uncertain, the certainty field on its page says so.
