AMD EPYC Embedded 9554P vs AMD EPYC Embedded 9755: Comparison
EPYC Embedded 9554P vs EPYC Embedded 9755: the l3 cache difference
On l3 cache the spread is 50%, EPYC Embedded 9554P 256 MB against EPYC Embedded 9755 512 MB, so EPYC Embedded 9755 takes it. There is a split on boost clock as well, 3.75 GHz on the EPYC Embedded 9554P versus 4.1 GHz on the EPYC Embedded 9755. There is a split on tdp as well, 360 W on the EPYC Embedded 9554P versus 500 W on the EPYC Embedded 9755. Core count is not the same on both, 64 cores on the EPYC Embedded 9554P versus 128 cores on the EPYC Embedded 9755. Thread count is not the same on both, 128 threads on the EPYC Embedded 9554P versus 256 threads on the EPYC Embedded 9755. They differ on core architecture too, Zen 4 on the EPYC Embedded 9554P versus Zen 5 on the EPYC Embedded 9755. They differ on base clock too, 3.1 GHz on the EPYC Embedded 9554P versus 2.7 GHz on the EPYC Embedded 9755. There is a split on multi-socket support as well, 1P on the EPYC Embedded 9554P versus Dual Socket on the EPYC Embedded 9755. There is a split on memory type as well, DDR5 on the EPYC Embedded 9554P versus DDR5 RDIMM on the EPYC Embedded 9755.
Who each one is for
Buy the EPYC Embedded 9554P 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. The EPYC Embedded 9755 is the one to take for 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.
Where the two are identical
The common ground is wider than the gap: pcie lanes and socket are identical here.
