AMD EPYC 9455P vs AMD EPYC Embedded 9745: Comparison
EPYC 9455P vs EPYC Embedded 9745 boost clock compared
Boost clock is the dividing line, EPYC 9455P 4.35 GHz against EPYC Embedded 9745 3.7 GHz. There is a split on tdp as well, 280 W on the EPYC 9455P versus 400 W on the EPYC Embedded 9745. Core count is not the same on both, 48 cores on the EPYC 9455P versus 128 cores on the EPYC Embedded 9745. They differ on thread count too, 96 threads on the EPYC 9455P versus 256 threads on the EPYC Embedded 9745. Core architecture is not the same on both, Zen 5 "Turin" on the EPYC 9455P versus Zen 5c on the EPYC Embedded 9745. They differ on base clock too, 3.15 GHz on the EPYC 9455P versus 2.4 GHz on the EPYC Embedded 9745. There is a split on multi-socket support as well, 1P on the EPYC 9455P versus Dual Socket on the EPYC Embedded 9745.
Who each one is for
Buy the EPYC 9455P 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 is the one to take 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 9455P (8.8/10): the EPYC 9455P 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.
