AMD EPYC 9554 vs AMD EPYC Embedded 9745: Comparison
What is the difference between EPYC 9554 and EPYC Embedded 9745?
Boost clock is the dividing line, EPYC 9554 3.75 GHz against EPYC Embedded 9745 3.7 GHz. There is a split on tdp as well, 360 W on the EPYC 9554 versus 400 W on the EPYC Embedded 9745. There is a split on core count as well, 64 cores on the EPYC 9554 versus 128 cores on the EPYC Embedded 9745. Thread count is not the same on both, 128 threads on the EPYC 9554 versus 256 threads on the EPYC Embedded 9745. There is a split on core architecture as well, Zen 4 "Genoa" on the EPYC 9554 versus Zen 5c on the EPYC Embedded 9745. Base clock is not the same on both, 3.1 GHz on the EPYC 9554 versus 2.4 GHz on the EPYC Embedded 9745. Multi-socket support is not the same on both, 1P/2P on the EPYC 9554 versus Dual Socket on the EPYC Embedded 9745.
EPYC 9554 vs EPYC Embedded 9745: which one fits your build
Buy the EPYC 9554 for virtualization hosts and database servers, though it is the wrong buy 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 built for consumer desktop or gaming builds and DIY PC upgrades. Our rating of the EPYC 9554 (8.8/10): the EPYC 9554 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
The common ground is wider than the gap: l3 cache, memory channels, socket and ecc support are identical here.
