Follow-up article from The Next Platform: "It is interesting to us that there are still six compute dies (XCDs in the AMD lingo) on the MI300A package that are perfectly balanced against six GPU chiplets. The “Frontier” supercomputer at Oak Ridge, the older sibling to El Capitan, also had a one-to-one ratio between custom “Trento” CPU XCDs (eight per node in a single chip) paired to a quad of discrete dual-chip “Aldebaran” MI250X GPUs. This one to one packaging has been maintained between CPUs and accelerators across many generations of Cray supercomputers, and this is probably not an accident. In a sense, the MI300A is a six-way X86 CPU server cross-coupled to a six-way GPU system board." “El Capitan” Supercomputer Blazes The Trail for Converged CPU-GPU Compute
