AMD EPYC 7343 vs AMD EPYC Embedded 7451: Comparison
What is the difference between EPYC 7343 and EPYC Embedded 7451?
The gap that matters here is l3 cache: EPYC 7343 128 MB against EPYC Embedded 7451 64 MB, which puts EPYC 7343 50% ahead. There is a split on boost clock as well, Up to 3.9 GHz on the EPYC 7343 versus 3.2 GHz on the EPYC Embedded 7451. Tdp is not the same on both, 190 W on the EPYC 7343 versus 180 W on the EPYC Embedded 7451. They differ on core count too, 16 cores on the EPYC 7343 versus 24 cores on the EPYC Embedded 7451. There is a split on thread count as well, 32 threads on the EPYC 7343 versus 48 threads on the EPYC Embedded 7451. Base clock is not the same on both, 3.2 GHz on the EPYC 7343 versus 2.3 GHz on the EPYC Embedded 7451.
Which should you buy, EPYC 7343 or EPYC Embedded 7451?
The EPYC 7343 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 7451 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
Everything else lines up. Pcie lanes and socket read the same on both, so those are not worth weighing.
