AMD EPYC 7543 vs AMD EPYC Embedded 7401: Comparison
EPYC 7543 vs EPYC Embedded 7401: the l3 cache difference
Start with l3 cache, because it is the widest measured gap between them: EPYC 7543 256 MB against EPYC Embedded 7401 64 MB, 75% in favour of EPYC 7543. Boost clock is not the same on both, Up to 3.7 GHz on the EPYC 7543 versus 3 GHz on the EPYC Embedded 7401. There is a split on tdp as well, 225 W on the EPYC 7543 versus 155 W on the EPYC Embedded 7401. They differ on core count too, 32 cores on the EPYC 7543 versus 24 cores on the EPYC Embedded 7401. There is a split on thread count as well, 64 threads on the EPYC 7543 versus 48 threads on the EPYC Embedded 7401. They differ on base clock too, 2.8 GHz on the EPYC 7543 versus 2 GHz on the EPYC Embedded 7401.
Which should you buy, EPYC 7543 or EPYC Embedded 7401?
The EPYC 7543 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. The EPYC Embedded 7401 is the one to take 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 7543 and EPYC Embedded 7401 have in common
The common ground is wider than the gap: pcie lanes and socket are identical here.
