AMD EPYC 9135 vs AMD EPYC Embedded 9555P: Comparison
EPYC 9135 vs EPYC Embedded 9555P: the l3 cache difference
On l3 cache the spread is 50%, EPYC 9135 128 MB against EPYC Embedded 9555P 256 MB, so EPYC Embedded 9555P takes it. There is a split on boost clock as well, 4.3 GHz on the EPYC 9135 versus 4.4 GHz on the EPYC Embedded 9555P. There is a split on tdp as well, 200 W on the EPYC 9135 versus 360 W on the EPYC Embedded 9555P. Core count is not the same on both, 16 cores on the EPYC 9135 versus 64 cores on the EPYC Embedded 9555P. There is a split on thread count as well, 32 threads on the EPYC 9135 versus 128 threads on the EPYC Embedded 9555P. Core architecture is not the same on both, Zen 5 "Turin" on the EPYC 9135 versus Zen 5 on the EPYC Embedded 9555P. Base clock is not the same on both, 3.65 GHz on the EPYC 9135 versus 3.2 GHz on the EPYC Embedded 9555P. They differ on multi-socket support too, 1P/2P on the EPYC 9135 versus Single Socket Only on the EPYC Embedded 9555P.
Who each one is for
The EPYC 9135 is the one to take for latency-sensitive web and application tiers and smaller database servers, though it is the wrong buy for maximum core density workloads and power-constrained edge deployments. The EPYC Embedded 9555P suits industrial and embedded system designs and long-lifecycle networking and edge-compute deployments, though it is not built for consumer desktop or gaming builds and DIY PC upgrades. Our rating of the EPYC 9135 (8.6/10): the EPYC 9135 is the pick within AMD's entry EPYC tier when per-thread speed matters more than shaving off every extra watt.
Where the two are identical
Where they agree, they agree completely, memory channels, socket and ecc support included, so the decision does not turn on any of those.
