Parts/Accelerators/AMD Instinct MI250X
Why this part
Two dies on one package, which AMD called a multi-chip module and which software sees as two devices unless told otherwise. Frontier's selection of it was the first time a US exascale flagship went to a vendor other than IBM or Intel at the accelerator layer, and it was a real risk: ROCm in 2021 was substantially less mature than CUDA, and the laboratories took on a porting effort to avoid single-vendor dependence. Frontier reaching number one validated the bet, and the maturity gap remains the honest counterargument.

“Units recorded” sums only the edges where a public source states a quantity. It is a floor, not a total, and should never be read as installed base.
