AMD EPYC Embedded 7443 vs AMD EPYC Embedded 7552: Comparison
EPYC Embedded 7443 vs EPYC Embedded 7552 l3 cache compared
On l3 cache the spread is 33%, EPYC Embedded 7443 128 MB against EPYC Embedded 7552 192 MB, so EPYC Embedded 7552 takes it. There is a split on boost clock as well, 4 GHz on the EPYC Embedded 7443 versus 3.3 GHz on the EPYC Embedded 7552. There is a split on core count as well, 24 cores on the EPYC Embedded 7443 versus 48 cores on the EPYC Embedded 7552. Thread count is not the same on both, 48 threads on the EPYC Embedded 7443 versus 96 threads on the EPYC Embedded 7552. Core architecture is not the same on both, Zen 3 on the EPYC Embedded 7443 versus Zen 2 on the EPYC Embedded 7552. They differ on base clock too, 2.85 GHz on the EPYC Embedded 7443 versus 2.2 GHz on the EPYC Embedded 7552. They differ on usb too, 4x USB 3.0 Gen1 on the EPYC Embedded 7443 versus 4x USB 3.1 Gen1 on the EPYC Embedded 7552.
Who each one is for
The EPYC Embedded 7443 suits 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. Buy the EPYC Embedded 7552 for industrial and embedded system designs and long-lifecycle networking and edge-compute deployments, though it is not built for consumer desktop or gaming builds and DIY PC upgrades.
Where the two are identical
Everything else lines up. Tdp, pcie lanes, socket, memory type and security processor read the same on both, so those are not worth weighing. They match on 3 further specifications as well.
Frequently asked questions
Is the Memory Controller the same on the EPYC Embedded 7443 and EPYC Embedded 7552?
It is. Both are listed at 8 Channel w/ECC, so it is not a reason to pick one over the other.
