AMD EPYC 9734 vs AMD EPYC Embedded 9555P: Comparison
What is the difference between EPYC 9734 and EPYC Embedded 9555P?
They are built to different briefs, and boost clock shows it, EPYC 9734 3.0 GHz against EPYC Embedded 9555P 4.4 GHz. They differ on tdp too, 320 W on the EPYC 9734 versus 360 W on the EPYC Embedded 9555P. They differ on core count too, 112 cores on the EPYC 9734 versus 64 cores on the EPYC Embedded 9555P. Thread count is not the same on both, 224 threads on the EPYC 9734 versus 128 threads on the EPYC Embedded 9555P. Core architecture is not the same on both, Zen 4c "Bergamo" on the EPYC 9734 versus Zen 5 on the EPYC Embedded 9555P. There is a split on base clock as well, 2.2 GHz on the EPYC 9734 versus 3.2 GHz on the EPYC Embedded 9555P. There is a split on multi-socket support as well, 1P/2P on the EPYC 9734 versus Single Socket Only on the EPYC Embedded 9555P.
Who each one is for
The EPYC 9734 is the one to take for dense virtualization hosts and cloud-native container platforms, though it is the wrong buy for small server deployments and per-core licensed software. Buy the EPYC Embedded 9555P for industrial and embedded system designs and long-lifecycle networking and edge-compute deployments, though it is not the pick for consumer desktop or gaming builds and DIY PC upgrades. Our rating of the EPYC 9734 (9/10): the EPYC 9734 offers very high core density for dense virtualization hosts without going all the way to AMD's 128-core flagship.
What EPYC 9734 and EPYC Embedded 9555P have in common
Where they agree, they agree completely, l3 cache, memory channels, socket and ecc support included, so the decision does not turn on any of those.
