AMD EPYC Embedded 7313 vs AMD EPYC Embedded 7662: Comparison
EPYC Embedded 7313 vs EPYC Embedded 7662: the l3 cache difference
The gap that matters here is l3 cache: EPYC Embedded 7313 128 MB against EPYC Embedded 7662 256 MB, which puts EPYC Embedded 7662 50% ahead. There is a split on boost clock as well, 3.7 GHz on the EPYC Embedded 7313 versus 3.3 GHz on the EPYC Embedded 7662. Tdp is not the same on both, 155 W on the EPYC Embedded 7313 versus 225 W on the EPYC Embedded 7662. They differ on core count too, 16 cores on the EPYC Embedded 7313 versus 64 cores on the EPYC Embedded 7662. Thread count is not the same on both, 32 threads on the EPYC Embedded 7313 versus 128 threads on the EPYC Embedded 7662. They differ on core architecture too, Zen 3 on the EPYC Embedded 7313 versus Zen 2 on the EPYC Embedded 7662. There is a split on base clock as well, 3 GHz on the EPYC Embedded 7313 versus 2 GHz on the EPYC Embedded 7662. Usb is not the same on both, 4x USB 3.0 Gen1 on the EPYC Embedded 7313 versus 4x USB 3.1 Gen1 on the EPYC Embedded 7662.
Who each one is for
The EPYC Embedded 7313 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. The EPYC Embedded 7662 suits 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. Pcie lanes, socket, memory type, security processor and memory controller read the same on both, so those are not worth weighing. They match on 2 further specifications as well.
Frequently asked questions
Is the SATA the same on the EPYC Embedded 7313 and EPYC Embedded 7662?
It is. Both are listed at 32, so it is not a reason to pick one over the other.
