AMD EPYC 9374F vs AMD EPYC Embedded 9845: Comparison
What is the difference between EPYC 9374F and EPYC Embedded 9845?
Start with l3 cache, because it is the widest measured gap between them: EPYC 9374F 256 MB against EPYC Embedded 9845 320 MB, 20% in favour of EPYC Embedded 9845. Boost clock is not the same on both, 4.3 GHz on the EPYC 9374F versus 3.7 GHz on the EPYC Embedded 9845. There is a split on tdp as well, 320 W on the EPYC 9374F versus 390 W on the EPYC Embedded 9845. They differ on core count too, 32 cores on the EPYC 9374F versus 160 cores on the EPYC Embedded 9845. Thread count is not the same on both, 64 threads on the EPYC 9374F versus 320 threads on the EPYC Embedded 9845. There is a split on core architecture as well, Zen 4 "Genoa" on the EPYC 9374F versus Zen 5c on the EPYC Embedded 9845. They differ on base clock too, 3.85 GHz on the EPYC 9374F versus 2.1 GHz on the EPYC Embedded 9845. Multi-socket support is not the same on both, 1P/2P on the EPYC 9374F versus Dual Socket on the EPYC Embedded 9845.
Which should you buy, EPYC 9374F or EPYC Embedded 9845?
The EPYC 9374F is the one to take for per-core licensed databases (Oracle, SQL Server) and EDA tools billed per core, though it is not built for massively parallel batch jobs and cost-per-core-sensitive deployments. Buy the EPYC Embedded 9845 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 9374F (8.9/10): the EPYC 9374F is the right call when per-core software licensing makes clock speed worth more than core count.
What EPYC 9374F and EPYC Embedded 9845 have in common
Everything else lines up. Memory channels, socket and ecc support read the same on both, so those are not worth weighing.
