AMD EPYC 7452 vs AMD EPYC Embedded 7642: Comparison
EPYC 7452 vs EPYC Embedded 7642: the l3 cache difference
L3 cache is where these two genuinely part company, EPYC 7452 128 MB against EPYC Embedded 7642 256 MB, a 50% lead for EPYC Embedded 7642. They differ on boost clock too, Up to 3.35 GHz on the EPYC 7452 versus 3.3 GHz on the EPYC Embedded 7642. They differ on tdp too, 155 W on the EPYC 7452 versus 225 W on the EPYC Embedded 7642. Core count is not the same on both, 32 cores on the EPYC 7452 versus 48 cores on the EPYC Embedded 7642. Thread count is not the same on both, 64 threads on the EPYC 7452 versus 96 threads on the EPYC Embedded 7642. There is a split on base clock as well, 2.35 GHz on the EPYC 7452 versus 2.3 GHz on the EPYC Embedded 7642.
Which should you buy, EPYC 7452 or EPYC Embedded 7642?
The EPYC 7452 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 7642 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 7452 and EPYC Embedded 7642 have in common
The common ground is wider than the gap: pcie lanes and socket are identical here.
