AMD Instinct MI250X
The chiplet GPU that powered Frontier, the first exascale supercomputer.
You're looking at a chip record: what this processor is, its key specs, who designs, manufactures and supplies its parts, and where it gets used.
The MI250X put two CDNA2 dies in one OAM package with 128 GB of HBM2e — AMD's chiplet strategy applied to accelerators before NVIDIA adopted multi-die designs. It powered Oak Ridge's Frontier, the machine that broke the exascale barrier in 2022, and established AMD as the alternative at the top of HPC.
