AMD EPYC 7351 vs AMD EPYC 7281: comparison

Comparison of AMD EPYC 7351 and AMD EPYC 7281: key differences and a full specification table.

Key differences

AMD EPYC 7351 has a higher base clock (2.4 GHz vs 2.1 GHz), a higher maximum clock (2.9 GHz vs 2.7 GHz) and a larger L3 cache (64 MB vs 32 MB).

Both processors match on: core count (16), thread count (32), 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.
