AMD EPYC 9274F vs AMD EPYC Embedded 9745: Comparison
EPYC 9274F vs EPYC Embedded 9745: the boost clock difference
Boost clock is the dividing line, EPYC 9274F 4.3 GHz against EPYC Embedded 9745 3.7 GHz. They differ on tdp too, 320 W on the EPYC 9274F versus 400 W on the EPYC Embedded 9745. Core count is not the same on both, 24 cores on the EPYC 9274F versus 128 cores on the EPYC Embedded 9745. There is a split on thread count as well, 48 threads on the EPYC 9274F versus 256 threads on the EPYC Embedded 9745. They differ on core architecture too, Zen 4 "Genoa" on the EPYC 9274F versus Zen 5c on the EPYC Embedded 9745. Base clock is not the same on both, 4.05 GHz on the EPYC 9274F versus 2.4 GHz on the EPYC Embedded 9745. There is a split on multi-socket support as well, 1P/2P on the EPYC 9274F versus Dual Socket on the EPYC Embedded 9745.
Which should you buy, EPYC 9274F or EPYC Embedded 9745?
Buy the EPYC 9274F for per-core licensed databases (Oracle, SQL Server) and EDA tools billed per core, though it is the wrong buy for massively parallel batch jobs and cost-per-core-sensitive deployments. 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 9274F (8.9/10): the EPYC 9274F is the right call when per-core software licensing makes clock speed worth more than core count.
What EPYC 9274F and EPYC Embedded 9745 have in common
Where they agree, they agree completely, l3 cache, memory channels, socket and ecc support included, so the decision does not turn on any of those.
