EPYC 7402P vs EPYC 7643 comparison
Our benchmark analysis concludes that the EPYC 7402P performs better than the EPYC 7643. Furthermore, our gaming benchmark shows that it also outperforms the EPYC 7643 in all gaming tests too.
With info from our database, we find that the EPYC 7643 has significantly more cores with 48 cores whereas the EPYC 7402P has 24 cores. It also has more threads than the EPYC 7402P. Our comparison shows that the EPYC 7402P has a slightly higher clock speed compared to the EPYC 7643. Despite this, the EPYC 7643 has a slightly higher turbo speed. A EPYC 7402P CPU outputs less heat than a EPYC 7643 CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the EPYC 7643 has significantly more L2 cache than the EPYC 7402P. The EPYC 7643 also has significantly more L3 cache.
Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the EPYC 7402P has more threads than cores. Each physical core is split into multiple threads.
