AMD EPYC 7401P vs AMD EPYC 7281: comparison
Comparison of AMD EPYC 7401P and AMD EPYC 7281: key differences and a full specification table.
Key differences
AMD EPYC 7401P has more cores (24 vs 16), more threads (48 vs 32), a higher maximum clock (3 GHz vs 2.7 GHz) and a larger L3 cache (64 MB vs 32 MB).
At the same time, AMD EPYC 7281 has a higher base clock (2.1 GHz vs 2 GHz).
Both processors match on: TDP (155–170 W), 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.
