AMD EPYC 9455 vs AMD EPYC Embedded 9655P: Comparison
EPYC 9455 vs EPYC Embedded 9655P: the l3 cache difference
On l3 cache the spread is 33%, EPYC 9455 256 MB against EPYC Embedded 9655P 384 MB, so EPYC Embedded 9655P takes it. There is a split on boost clock as well, 4.35 GHz on the EPYC 9455 versus 4.5 GHz on the EPYC Embedded 9655P. There is a split on tdp as well, 280 W on the EPYC 9455 versus 400 W on the EPYC Embedded 9655P. Core count is not the same on both, 48 cores on the EPYC 9455 versus 96 cores on the EPYC Embedded 9655P. There is a split on thread count as well, 96 threads on the EPYC 9455 versus 192 threads on the EPYC Embedded 9655P. Core architecture is not the same on both, Zen 5 "Turin" on the EPYC 9455 versus Zen 5 on the EPYC Embedded 9655P. Base clock is not the same on both, 3.15 GHz on the EPYC 9455 versus 2.6 GHz on the EPYC Embedded 9655P. They differ on multi-socket support too, 1P/2P on the EPYC 9455 versus Single Socket Only on the EPYC Embedded 9655P.
EPYC 9455 vs EPYC Embedded 9655P: which one fits your build
The EPYC 9455 suits virtualization hosts and database servers, though it is not the pick for cost-sensitive small deployments and single-threaded legacy applications. Buy the EPYC Embedded 9655P for industrial and embedded system designs and long-lifecycle networking and edge-compute deployments, though it is the wrong buy 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.
Where the two are identical
Everything else lines up. Memory channels, socket and ecc support read the same on both, so those are not worth weighing.
