Frontier (Oak Ridge)
The first exascale computer — public-sector proof of AMD's stack.
You're looking at a data-center record: a real facility — who runs it, what hardware fills it, and where its power comes from.

Frontier at Oak Ridge National Laboratory broke the exascale barrier in 2022: 9,472 nodes of AMD EPYC + MI250X on HPE Cray EX with Slingshot interconnect, ~21 MW at full load. It anchors US open science and showed a full non-NVIDIA stack at the very top of computing.
