AMD EPYC 7542 vs AMD EPYC Embedded 7301: Comparison
EPYC 7542 vs EPYC Embedded 7301: the l3 cache difference
L3 cache is where these two genuinely part company, EPYC 7542 128 MB against EPYC Embedded 7301 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 2.9 GHz on the EPYC Embedded 7301. Tdp is not the same on both, 225 W on the EPYC 7542 versus 155 W on the EPYC Embedded 7301. There is a split on core count as well, 32 cores on the EPYC 7542 versus 16 cores on the EPYC Embedded 7301. There is a split on thread count as well, 64 threads on the EPYC 7542 versus 32 threads on the EPYC Embedded 7301. They differ on base clock too, 2.9 GHz on the EPYC 7542 versus 2.2 GHz on the EPYC Embedded 7301.
Which should you buy, EPYC 7542 or EPYC Embedded 7301?
Buy the EPYC 7542 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 7301 suits 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.
What EPYC 7542 and EPYC Embedded 7301 have in common
Where they agree, they agree completely, pcie lanes and socket included, so the decision does not turn on any of those.
