AMD EPYC 7401 vs AMD EPYC Embedded 7402: Comparison
EPYC 7401 vs EPYC Embedded 7402: the l3 cache difference
Start with l3 cache, because it is the widest measured gap between them: EPYC 7401 64 MB against EPYC Embedded 7402 128 MB, 50% in favour of EPYC Embedded 7402. Boost clock is not the same on both, Up to 3 GHz on the EPYC 7401 versus 3.35 GHz on the EPYC Embedded 7402. There is a split on tdp as well, 155W / 170W on the EPYC 7401 versus 180 W on the EPYC Embedded 7402. They differ on base clock too, 2 GHz on the EPYC 7401 versus 2.8 GHz on the EPYC Embedded 7402.
EPYC 7401 vs EPYC Embedded 7402: which one fits your build
The EPYC 7401 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. Buy the EPYC Embedded 7402 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 7401 and EPYC Embedded 7402 have in common
Where they agree, they agree completely, pcie lanes, core count, thread count and socket included, so the decision does not turn on any of those.
