xAI Colossus 2
The gigawatt sequel: xAI's push toward a million-GPU class site.
You're looking at a data-center record: a real facility — who runs it, what hardware fills it, and where its power comes from.
xAI's second Memphis-area campus pairs a new data hall complex with a dedicated power build-out (including generation across the state line in Mississippi). Musk has stated ambitions of a million GPUs across the Colossus program; first GB200/GB300 capacity came up in 2025. Figures are company statements and reporting, not audited totals.
Specifications & key facts
Each figure is labeled by basis: vendor spec, vendor claim, reported, estimate, or official. "Not publicly disclosed" means exactly that — we never invent values.
