Server CPUs based on Zen 4 are rumored to be massive chips and will power the world’s fastest supercomputer when they arrive.
AMD has not yet released its fourth generation EPYC „Milan“ server processors based on its Zen 3 CPU architecture, but barring any last minute snags, those chips are coming any day now. Looking further down the road, a new leak highlights a possible fourth generation EPYC „Genoa“ configuration based on Zen 4, with some interesting details. Up to this point, details about Genoa have been rather scarce. We know it will be built on TSMC’s 5-nanometer manufacturing process, and that it will power El Capitan, which is set to become the world’s most powerful supercomputer when it is fully deployed in 2023. The latter revelation comes by way of a joint announcement between AMD, Hewlett Packard Enterprise (HPE), and Lawrence Livermore National Laboratory (LLNL). „El Capitan will be powered by next-generation AMD EPYC processors, code-named ‚Genoa‘ and featuring the ‚Zen 4‘ processor core, next-generation AMD Radeon Instinct GPUs based on a new compute-optimized architecture for workloads including HPC and AI, and the AMD Radeon Open Compute platform (ROCm) heterogenous computing software,“ LLNL said last year.
