The speed-to-market systems that built Colossus.
You're looking at a system record: an assembled machine — a server or a whole rack — with what's inside it and where it's deployed.
Supermicro's liquid-cooled 4U H100/H200 systems and GB200 NVL72 racks ship with its own CDUs and cold plates — vertical integration that made it the fastest supplier at each generation change and xAI's lead systems partner for Colossus.
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.
