AMD EPYC Embedded 7302 vs AMD EPYC Embedded 7543P: Comparison
EPYC Embedded 7302 vs EPYC Embedded 7543P: the l3 cache difference
The gap that matters here is l3 cache: EPYC Embedded 7302 128 MB against EPYC Embedded 7543P 256 MB, which puts EPYC Embedded 7543P 50% ahead. Boost clock is not the same on both, 3.3 GHz on the EPYC Embedded 7302 versus 3.7 GHz on the EPYC Embedded 7543P. They differ on tdp too, 155 W on the EPYC Embedded 7302 versus 225 W on the EPYC Embedded 7543P. There is a split on core count as well, 16 cores on the EPYC Embedded 7302 versus 32 cores on the EPYC Embedded 7543P. They differ on thread count too, 32 threads on the EPYC Embedded 7302 versus 64 threads on the EPYC Embedded 7543P. There is a split on core architecture as well, Zen 2 on the EPYC Embedded 7302 versus Zen 3 on the EPYC Embedded 7543P. Base clock is not the same on both, 3 GHz on the EPYC Embedded 7302 versus 2.8 GHz on the EPYC Embedded 7543P. They differ on usb too, 4x USB 3.1 Gen1 on the EPYC Embedded 7302 versus 4x USB 3.0 Gen1 on the EPYC Embedded 7543P.
Who each one is for
Buy the EPYC Embedded 7302 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. The EPYC Embedded 7543P is the one to take 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, socket, memory type, security processor and memory controller are identical here. They match on 2 further specifications as well.
Frequently asked questions
Is the SATA the same on the EPYC Embedded 7302 and EPYC Embedded 7543P?
It is. Both are listed at 32, so it is not a reason to pick one over the other.
