AMD EPYC Embedded 9454P vs AMD EPYC Embedded 9745: Comparison
EPYC Embedded 9454P vs EPYC Embedded 9745: the boost clock difference
The first real difference is boost clock: EPYC Embedded 9454P 3.8 GHz against EPYC Embedded 9745 3.7 GHz. There is a split on tdp as well, 290 W on the EPYC Embedded 9454P versus 400 W on the EPYC Embedded 9745. There is a split on core count as well, 48 cores on the EPYC Embedded 9454P versus 128 cores on the EPYC Embedded 9745. Thread count is not the same on both, 96 threads on the EPYC Embedded 9454P versus 256 threads on the EPYC Embedded 9745. There is a split on core architecture as well, Zen 4 on the EPYC Embedded 9454P versus Zen 5c on the EPYC Embedded 9745. Base clock is not the same on both, 2.75 GHz on the EPYC Embedded 9454P versus 2.4 GHz on the EPYC Embedded 9745. Multi-socket support is not the same on both, 1P on the EPYC Embedded 9454P versus Dual Socket on the EPYC Embedded 9745. They differ on memory type too, DDR5 on the EPYC Embedded 9454P versus DDR5 RDIMM on the EPYC Embedded 9745.
Who each one is for
Buy the EPYC Embedded 9454P 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
Everything else lines up. L3 cache, pcie lanes and socket read the same on both, so those are not worth weighing.
