AMD EPYC Embedded 9554P vs AMD EPYC Embedded 9745: Comparison
EPYC Embedded 9554P vs EPYC Embedded 9745 boost clock compared
They are built to different briefs, and boost clock shows it, EPYC Embedded 9554P 3.75 GHz against EPYC Embedded 9745 3.7 GHz. They differ on tdp too, 360 W on the EPYC Embedded 9554P versus 400 W on the EPYC Embedded 9745. Core count is not the same on both, 64 cores on the EPYC Embedded 9554P versus 128 cores on the EPYC Embedded 9745. There is a split on thread count as well, 128 threads on the EPYC Embedded 9554P versus 256 threads on the EPYC Embedded 9745. Core architecture is not the same on both, Zen 4 on the EPYC Embedded 9554P versus Zen 5c on the EPYC Embedded 9745. There is a split on base clock as well, 3.1 GHz on the EPYC Embedded 9554P versus 2.4 GHz on the EPYC Embedded 9745. They differ on multi-socket support too, 1P on the EPYC Embedded 9554P versus Dual Socket on the EPYC Embedded 9745. Memory type is not the same on both, DDR5 on the EPYC Embedded 9554P versus DDR5 RDIMM on the EPYC Embedded 9745.
Which should you buy, EPYC Embedded 9554P or EPYC Embedded 9745?
The EPYC Embedded 9554P suits 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. 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 the wrong buy for consumer desktop or gaming builds and DIY PC upgrades.
What EPYC Embedded 9554P and EPYC Embedded 9745 have in common
Everything else lines up. L3 cache, pcie lanes and socket read the same on both, so those are not worth weighing.
