AMD EPYC 7351 vs AMD EPYC Embedded 7401: Comparison
What is the difference between EPYC 7351 and EPYC Embedded 7401?
They are built to different briefs, and boost clock shows it, EPYC 7351 Up to 2.9 GHz against EPYC Embedded 7401 3 GHz. There is a split on tdp as well, 155W / 170W on the EPYC 7351 versus 155 W on the EPYC Embedded 7401. There is a split on core count as well, 16 cores on the EPYC 7351 versus 24 cores on the EPYC Embedded 7401. Thread count is not the same on both, 32 threads on the EPYC 7351 versus 48 threads on the EPYC Embedded 7401. Base clock is not the same on both, 2.4 GHz on the EPYC 7351 versus 2 GHz on the EPYC Embedded 7401.
Who each one is for
The EPYC 7351 is the one to take for 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 7401 suits 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.
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.
