AMD EPYC 7402P vs AMD EPYC Embedded 7251: Comparison
What is the difference between EPYC 7402P and EPYC Embedded 7251?
On l3 cache the spread is 75%, EPYC 7402P 128 MB against EPYC Embedded 7251 32 MB, so EPYC 7402P takes it. There is a split on boost clock as well, Up to 3.35 GHz on the EPYC 7402P versus 2.9 GHz on the EPYC Embedded 7251. There is a split on tdp as well, 180 W on the EPYC 7402P versus 120 W on the EPYC Embedded 7251. Core count is not the same on both, 24 cores on the EPYC 7402P versus 8 cores on the EPYC Embedded 7251. Thread count is not the same on both, 48 threads on the EPYC 7402P versus 16 threads on the EPYC Embedded 7251. They differ on base clock too, 2.8 GHz on the EPYC 7402P versus 2.1 GHz on the EPYC Embedded 7251.
Which should you buy, EPYC 7402P or EPYC Embedded 7251?
The EPYC 7402P suits 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. Buy the EPYC Embedded 7251 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, pcie lanes and socket included, so the decision does not turn on any of those.
