AMD EPYC 7663 vs AMD EPYC Embedded 7402P: Comparison
What is the difference between EPYC 7663 and EPYC Embedded 7402P?
L3 cache is where these two genuinely part company, EPYC 7663 256 MB against EPYC Embedded 7402P 128 MB, a 50% lead for EPYC 7663. They differ on boost clock too, Up to 3.5 GHz on the EPYC 7663 versus 3.35 GHz on the EPYC Embedded 7402P. They differ on tdp too, 240 W on the EPYC 7663 versus 180 W on the EPYC Embedded 7402P. Core count is not the same on both, 56 cores on the EPYC 7663 versus 24 cores on the EPYC Embedded 7402P. They differ on thread count too, 112 threads on the EPYC 7663 versus 48 threads on the EPYC Embedded 7402P. Base clock is not the same on both, 2 GHz on the EPYC 7663 versus 2.8 GHz on the EPYC Embedded 7402P.
Who each one is for
Buy the EPYC 7663 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 7402P 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 7663 and EPYC Embedded 7402P have in common
Where they agree, they agree completely, pcie lanes and socket included, so the decision does not turn on any of those.
