AMD EPYC 7401 vs AMD EPYC Embedded 7251: Comparison
EPYC 7401 vs EPYC Embedded 7251 l3 cache compared
L3 cache is where these two genuinely part company, EPYC 7401 64 MB against EPYC Embedded 7251 32 MB, a 50% lead for EPYC 7401. Boost clock is not the same on both, Up to 3 GHz on the EPYC 7401 versus 2.9 GHz on the EPYC Embedded 7251. Tdp is not the same on both, 155W / 170W on the EPYC 7401 versus 120 W on the EPYC Embedded 7251. There is a split on core count as well, 24 cores on the EPYC 7401 versus 8 cores on the EPYC Embedded 7251. There is a split on thread count as well, 48 threads on the EPYC 7401 versus 16 threads on the EPYC Embedded 7251. They differ on base clock too, 2 GHz on the EPYC 7401 versus 2.1 GHz on the EPYC Embedded 7251.
EPYC 7401 vs EPYC Embedded 7251: which one fits your build
The EPYC 7401 is the one to take 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. Buy the EPYC Embedded 7251 for industrial and embedded system designs and long-lifecycle networking and edge-compute deployments, though it is the wrong buy for consumer desktop or gaming builds and DIY PC upgrades.
What EPYC 7401 and EPYC Embedded 7251 have in common
Everything else lines up. Pcie lanes and socket read the same on both, so those are not worth weighing.
