AMD EPYC Embedded 9454 vs AMD EPYC Embedded 9745: Comparison
EPYC Embedded 9454 vs EPYC Embedded 9745: the boost clock difference
Boost clock is the dividing line, EPYC Embedded 9454 3.8 GHz against EPYC Embedded 9745 3.7 GHz. Tdp is not the same on both, 290 W on the EPYC Embedded 9454 versus 400 W on the EPYC Embedded 9745. They differ on core count too, 48 cores on the EPYC Embedded 9454 versus 128 cores on the EPYC Embedded 9745. There is a split on thread count as well, 96 threads on the EPYC Embedded 9454 versus 256 threads on the EPYC Embedded 9745. Core architecture is not the same on both, Zen 4 on the EPYC Embedded 9454 versus Zen 5c on the EPYC Embedded 9745. They differ on base clock too, 2.75 GHz on the EPYC Embedded 9454 versus 2.4 GHz on the EPYC Embedded 9745. There is a split on multi-socket support as well, 1P/2P on the EPYC Embedded 9454 versus Dual Socket on the EPYC Embedded 9745. Memory type is not the same on both, DDR5 on the EPYC Embedded 9454 versus DDR5 RDIMM on the EPYC Embedded 9745.
Which should you buy, EPYC Embedded 9454 or EPYC Embedded 9745?
Buy the EPYC Embedded 9454 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. 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.
Where the two are identical
Where they agree, they agree completely, l3 cache, pcie lanes and socket included, so the decision does not turn on any of those.
