AMD EPYC 9734 vs AMD EPYC 9684X: comparison
Comparison of AMD EPYC 9734 and AMD EPYC 9684X: key differences and a full specification table.
Key differences
AMD EPYC 9734 has more cores (112 vs 96), more threads (224 vs 192) and a lower TDP (340 W vs 400 W).
At the same time, AMD EPYC 9684X has a higher base clock (2.55 GHz vs 2.2 GHz), a higher maximum clock (3.7 GHz vs 3 GHz) and a larger L3 cache (1,152 MB vs 256 MB).
Both processors match on: memory channels (12), PCIe version (5).
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.
