AMD EPYC 7301 vs AMD EPYC Embedded 7642: Comparison
What is the difference between EPYC 7301 and EPYC Embedded 7642?
The gap that matters here is l3 cache: EPYC 7301 64 MB against EPYC Embedded 7642 256 MB, which puts EPYC Embedded 7642 75% ahead. There is a split on boost clock as well, Up to 2.7 GHz on the EPYC 7301 versus 3.3 GHz on the EPYC Embedded 7642. Tdp is not the same on both, 155W / 170W on the EPYC 7301 versus 225 W on the EPYC Embedded 7642. They differ on core count too, 16 cores on the EPYC 7301 versus 48 cores on the EPYC Embedded 7642. Thread count is not the same on both, 32 threads on the EPYC 7301 versus 96 threads on the EPYC Embedded 7642. They differ on base clock too, 2.2 GHz on the EPYC 7301 versus 2.3 GHz on the EPYC Embedded 7642.
Who each one is for
Buy the EPYC 7301 for datacenter and cloud compute and virtualization-dense server workloads, though it is the wrong buy for consumer desktop builds and single-threaded latency-sensitive workloads on lower core-count SKUs. The EPYC Embedded 7642 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
Where they agree, they agree completely, pcie lanes and socket included, so the decision does not turn on any of those.
