AMD EPYC 7663 vs AMD EPYC Embedded 7742: Comparison
EPYC 7663 vs EPYC Embedded 7742 boost clock compared
They are built to different briefs, and boost clock shows it, EPYC 7663 Up to 3.5 GHz against EPYC Embedded 7742 3.4 GHz. They differ on tdp too, 240 W on the EPYC 7663 versus 225 W on the EPYC Embedded 7742. There is a split on core count as well, 56 cores on the EPYC 7663 versus 64 cores on the EPYC Embedded 7742. Thread count is not the same on both, 112 threads on the EPYC 7663 versus 128 threads on the EPYC Embedded 7742. They differ on base clock too, 2 GHz on the EPYC 7663 versus 2.25 GHz on the EPYC Embedded 7742.
Which should you buy, EPYC 7663 or EPYC Embedded 7742?
Buy the EPYC 7663 for datacenter and cloud compute and virtualization-dense server workloads, though it is not built for consumer desktop builds and single-threaded latency-sensitive workloads on lower core-count SKUs. The EPYC Embedded 7742 is the one to take for 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.
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.
