AMD EPYC 9554P vs AMD EPYC Embedded 9745: Comparison
EPYC 9554P vs EPYC Embedded 9745: the boost clock difference
The first real difference is boost clock: EPYC 9554P 3.75 GHz against EPYC Embedded 9745 3.7 GHz. Tdp is not the same on both, 360 W on the EPYC 9554P versus 400 W on the EPYC Embedded 9745. They differ on core count too, 64 cores on the EPYC 9554P versus 128 cores on the EPYC Embedded 9745. There is a split on thread count as well, 128 threads on the EPYC 9554P versus 256 threads on the EPYC Embedded 9745. Core architecture is not the same on both, Zen 4 "Genoa" on the EPYC 9554P versus Zen 5c on the EPYC Embedded 9745. They differ on base clock too, 3.1 GHz on the EPYC 9554P versus 2.4 GHz on the EPYC Embedded 9745. There is a split on multi-socket support as well, 1P on the EPYC 9554P versus Dual Socket on the EPYC Embedded 9745.
Who each one is for
The EPYC 9554P is the one to take for virtualization hosts and database servers, though it is not built for cost-sensitive small deployments and single-threaded legacy applications. The EPYC Embedded 9745 suits 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 9554P (8.8/10): the EPYC 9554P 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. L3 cache, memory channels, socket and ecc support read the same on both, so those are not worth weighing.
