AMD EPYC 7452 vs AMD EPYC Embedded 7742: Comparison
What is the difference between EPYC 7452 and EPYC Embedded 7742?
On l3 cache the spread is 50%, EPYC 7452 128 MB against EPYC Embedded 7742 256 MB, so EPYC Embedded 7742 takes it. There is a split on boost clock as well, Up to 3.35 GHz on the EPYC 7452 versus 3.4 GHz on the EPYC Embedded 7742. There is a split on tdp as well, 155 W on the EPYC 7452 versus 225 W on the EPYC Embedded 7742. Core count is not the same on both, 32 cores on the EPYC 7452 versus 64 cores on the EPYC Embedded 7742. Thread count is not the same on both, 64 threads on the EPYC 7452 versus 128 threads on the EPYC Embedded 7742. They differ on base clock too, 2.35 GHz on the EPYC 7452 versus 2.25 GHz on the EPYC Embedded 7742.
Who each one is for
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. Buy the EPYC Embedded 7742 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
The common ground is wider than the gap: pcie lanes and socket are identical here.
