AMD EPYC 9455 vs AMD EPYC Embedded 9555P: Comparison
What is the difference between EPYC 9455 and EPYC Embedded 9555P?
Boost clock is the dividing line, EPYC 9455 4.35 GHz against EPYC Embedded 9555P 4.4 GHz. Tdp is not the same on both, 280 W on the EPYC 9455 versus 360 W on the EPYC Embedded 9555P. Core count is not the same on both, 48 cores on the EPYC 9455 versus 64 cores on the EPYC Embedded 9555P. There is a split on thread count as well, 96 threads on the EPYC 9455 versus 128 threads on the EPYC Embedded 9555P. Core architecture is not the same on both, Zen 5 "Turin" on the EPYC 9455 versus Zen 5 on the EPYC Embedded 9555P. There is a split on base clock as well, 3.15 GHz on the EPYC 9455 versus 3.2 GHz on the EPYC Embedded 9555P. There is a split on multi-socket support as well, 1P/2P on the EPYC 9455 versus Single Socket Only on the EPYC Embedded 9555P.
EPYC 9455 vs EPYC Embedded 9555P: which one fits your build
Buy the EPYC 9455 for virtualization hosts and database servers, though it is not the pick for cost-sensitive small deployments and single-threaded legacy applications. 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 9455 (8.8/10): the EPYC 9455 is a well-rounded high-core-count EPYC SKU that balances density, clocks, and power draw for mainstream data center use.
What EPYC 9455 and EPYC Embedded 9555P have in common
The common ground is wider than the gap: l3 cache, memory channels, socket and ecc support are identical here.
