System GPU Baseboard Shipping

AMD's 8-GPU answer to HGX — the OAM board with 1.5 TB of HBM.

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.

AMD's universal baseboard carries eight MI300X/MI325X OAM modules linked by Infinity Fabric — 1.5 TB (MI300X) to 2 TB (MI325X) of HBM per system, the capacity pitch that won Microsoft and Meta serving deployments. Dell, Supermicro, Lenovo and HPE all build on it.

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.
