AMD EPYC 7552 vs AMD EPYC Embedded 7642: Comparison
EPYC 7552 vs EPYC Embedded 7642 l3 cache compared
On l3 cache the spread is 25%, EPYC 7552 192 MB against EPYC Embedded 7642 256 MB, so EPYC Embedded 7642 takes it. Boost clock is not the same on both, Up to 3.3 GHz on the EPYC 7552 versus 3.3 GHz on the EPYC Embedded 7642. Tdp is not the same on both, 200 W on the EPYC 7552 versus 225 W on the EPYC Embedded 7642. They differ on base clock too, 2.2 GHz on the EPYC 7552 versus 2.3 GHz on the EPYC Embedded 7642.
Who each one is for
The EPYC 7552 suits datacenter and cloud compute and virtualization-dense server workloads, though it is not the pick for consumer desktop builds and single-threaded latency-sensitive workloads on lower core-count SKUs. Buy the EPYC Embedded 7642 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.
Where the two are identical
Everything else lines up. Pcie lanes, core count, thread count and socket read the same on both, so those are not worth weighing.
