AMD EPYC 7663 vs AMD EPYC 75F3: comparison
Comparison of AMD EPYC 7663 and AMD EPYC 75F3: key differences and a full specification table.
Key differences
AMD EPYC 7663 has more cores (56 vs 32), more threads (112 vs 64) and a lower TDP (240 W vs 280 W).
At the same time, AMD EPYC 75F3 has a higher base clock (2.95 GHz vs 2 GHz) and a higher maximum clock (4 GHz vs 3.5 GHz).
Both processors match on: L3 cache (256 MB), 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.
