AMD EPYC 7542 vs AMD EPYC Embedded 7451: Comparison
EPYC 7542 vs EPYC Embedded 7451 l3 cache compared
L3 cache is where these two genuinely part company, EPYC 7542 128 MB against EPYC Embedded 7451 64 MB, a 50% lead for EPYC 7542. Boost clock is not the same on both, Up to 3.4 GHz on the EPYC 7542 versus 3.2 GHz on the EPYC Embedded 7451. Tdp is not the same on both, 225 W on the EPYC 7542 versus 180 W on the EPYC Embedded 7451. There is a split on core count as well, 32 cores on the EPYC 7542 versus 24 cores on the EPYC Embedded 7451. Thread count is not the same on both, 64 threads on the EPYC 7542 versus 48 threads on the EPYC Embedded 7451. There is a split on base clock as well, 2.9 GHz on the EPYC 7542 versus 2.3 GHz on the EPYC Embedded 7451.
Who each one is for
The EPYC 7542 suits datacenter and cloud compute and virtualization-dense server workloads, though it is not the pick for consumer desktop builds and single-threaded latency-sensitive workloads on lower core-count SKUs. The EPYC Embedded 7451 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.
What EPYC 7542 and EPYC Embedded 7451 have in common
The common ground is wider than the gap: pcie lanes and socket are identical here.
