AMD EPYC Embedded 7302 vs AMD EPYC Embedded 7543: Comparison
What is the difference between EPYC Embedded 7302 and EPYC Embedded 7543?
On l3 cache the spread is 50%, EPYC Embedded 7302 128 MB against EPYC Embedded 7543 256 MB, so EPYC Embedded 7543 takes it. Boost clock is not the same on both, 3.3 GHz on the EPYC Embedded 7302 versus 3.7 GHz on the EPYC Embedded 7543. Tdp is not the same on both, 155 W on the EPYC Embedded 7302 versus 225 W on the EPYC Embedded 7543. They differ on core count too, 16 cores on the EPYC Embedded 7302 versus 32 cores on the EPYC Embedded 7543. Thread count is not the same on both, 32 threads on the EPYC Embedded 7302 versus 64 threads on the EPYC Embedded 7543. They differ on core architecture too, Zen 2 on the EPYC Embedded 7302 versus Zen 3 on the EPYC Embedded 7543. They differ on base clock too, 3 GHz on the EPYC Embedded 7302 versus 2.8 GHz on the EPYC Embedded 7543. There is a split on usb as well, 4x USB 3.1 Gen1 on the EPYC Embedded 7302 versus 4x USB 3.0 Gen1 on the EPYC Embedded 7543.
Which should you buy, EPYC Embedded 7302 or EPYC Embedded 7543?
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 7543 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
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 7302 and EPYC Embedded 7543?
It is. Both are listed at 32, so it is not a reason to pick one over the other.
