AMD EPYC Embedded 7351 vs AMD EPYC Embedded 7543P: Comparison
What is the difference between EPYC Embedded 7351 and EPYC Embedded 7543P?
The gap that matters here is l3 cache: EPYC Embedded 7351 64 MB against EPYC Embedded 7543P 256 MB, which puts EPYC Embedded 7543P 75% ahead. Boost clock is not the same on both, 2.9 GHz on the EPYC Embedded 7351 versus 3.7 GHz on the EPYC Embedded 7543P. They differ on tdp too, 155 W on the EPYC Embedded 7351 versus 225 W on the EPYC Embedded 7543P. There is a split on core count as well, 16 cores on the EPYC Embedded 7351 versus 32 cores on the EPYC Embedded 7543P. They differ on thread count too, 32 threads on the EPYC Embedded 7351 versus 64 threads on the EPYC Embedded 7543P. There is a split on core architecture as well, Zen on the EPYC Embedded 7351 versus Zen 3 on the EPYC Embedded 7543P. Base clock is not the same on both, 2.4 GHz on the EPYC Embedded 7351 versus 2.8 GHz on the EPYC Embedded 7543P. They differ on memory type too, DDR4-2667 on the EPYC Embedded 7351 versus DDR4-3200 on the EPYC Embedded 7543P. They differ on usb too, 4x USB 3.1 Gen1 on the EPYC Embedded 7351 versus 4x USB 3.0 Gen1 on the EPYC Embedded 7543P.
EPYC Embedded 7351 vs EPYC Embedded 7543P: which one fits your build
The EPYC Embedded 7351 is the one to take 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 suits 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, security processor, memory controller and sata are identical here. They match on 1 further specification as well.
Frequently asked questions
Is the Low Speed Interfaces the same on the EPYC Embedded 7351 and EPYC Embedded 7543P?
It is. Both are listed at GPIO , I2C , LPC , SMBus , SPI..., so it is not a reason to pick one over the other.
