AMD EPYC 7501 vs AMD EPYC 7451: comparison
Comparison of AMD EPYC 7501 and AMD EPYC 7451: key differences and a full specification table.
Key differences
AMD EPYC 7501 has more cores (32 vs 24), more threads (64 vs 48) and a lower TDP (155–170 W vs 180 W).
At the same time, AMD EPYC 7451 has a higher base clock (2.3 GHz vs 2 GHz) and a higher maximum clock (3.2 GHz vs 3 GHz).
Both processors match on: L3 cache (64 MB), memory channels (8), PCIe version (3).
These are specification values: they show differences between the models but do not determine a performance winner. For a specific workload, rely on independent benchmarks.
