AMD EPYC 7773X vs AMD EPYC 7763: comparison

Comparison of AMD EPYC 7773X and AMD EPYC 7763: key differences and a full specification table.

Key differences

AMD EPYC 7773X has a larger L3 cache (768 MB vs 256 MB).

At the same time, AMD EPYC 7763 has a higher base clock (2.45 GHz vs 2.2 GHz).

Both processors match on: core count (64), thread count (128), maximum clock (3.5 GHz), TDP (280 W), memory channels (8), PCIe version (4).

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.
