AMD EPYC 9356 vs AMD EPYC 9456P: Comparison
EPYC 9356 vs EPYC 9456P l3 cache compared
On l3 cache the spread is 25%, EPYC 9356 192 MB against EPYC 9456P 256 MB, so EPYC 9456P takes it. There is a split on boost clock as well, 4.5 GHz on the EPYC 9356 versus 3.7 GHz on the EPYC 9456P. There is a split on tdp as well, 250 W on the EPYC 9356 versus 265 W on the EPYC 9456P. Core count is not the same on both, 32 cores on the EPYC 9356 versus 48 cores on the EPYC 9456P. Thread count is not the same on both, 64 threads on the EPYC 9356 versus 96 threads on the EPYC 9456P. They differ on base clock too, 3.6 GHz on the EPYC 9356 versus 3.2 GHz on the EPYC 9456P. They differ on multi-socket support too, Dual Socket on the EPYC 9356 versus Single Socket Only on the EPYC 9456P.
Who each one is for
The EPYC 9356 is the one to take for datacenter and cloud compute and virtualization-dense server workloads, though it is not the pick for consumer desktop builds and single-threaded latency-sensitive workloads on lower core-count SKUs. The EPYC 9456P suits datacenter and cloud compute and virtualization-dense server workloads, though it is the wrong buy for consumer desktop builds and single-threaded latency-sensitive workloads on lower core-count SKUs.
Where the two are identical
The common ground is wider than the gap: configurable tdp max, memory channels, pcie lanes, cpu socket and product family are identical here. They match on 10 further specifications as well.
Frequently asked questions
Is the Segment the same on the EPYC 9356 and EPYC 9456P?
It is. Both are listed at Data Center, so it is not a reason to pick one over the other.
