AMD EPYC 7443 vs AMD EPYC 7343: comparison
Comparison of AMD EPYC 7443 and AMD EPYC 7343: key differences and a full specification table.
Key differences
AMD EPYC 7443 has more cores (24 vs 16), more threads (48 vs 32) and a higher maximum clock (4 GHz vs 3.9 GHz).
At the same time, AMD EPYC 7343 has a higher base clock (3.2 GHz vs 2.85 GHz) and a lower TDP (190 W vs 200 W).
Both processors match on: L3 cache (128 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.
