AMD EPYC Embedded 3151 vs AMD EPYC Embedded 3251: Comparison
What is the difference between EPYC Embedded 3151 and EPYC Embedded 3251?
They are built to different briefs, and boost clock shows it, EPYC Embedded 3151 2.9 GHz against EPYC Embedded 3251 3.1 GHz. Tdp is not the same on both, 45 W on the EPYC Embedded 3151 versus 55 W on the EPYC Embedded 3251. L2 cache runs the same way, 2 MB on the EPYC Embedded 3151 versus 4 MB on the EPYC Embedded 3251, another win for EPYC Embedded 3251. They differ on core count too, 4 cores on the EPYC Embedded 3151 versus 8 cores on the EPYC Embedded 3251. They differ on thread count too, 8 threads on the EPYC Embedded 3151 versus 16 threads on the EPYC Embedded 3251. There is a split on base clock as well, 2.7 GHz on the EPYC Embedded 3151 versus 2.5 GHz on the EPYC Embedded 3251. There is a split on junction temp range as well, 0-95°C on the EPYC Embedded 3151 versus 0-105°C on the EPYC Embedded 3251.
Which should you buy, EPYC Embedded 3151 or EPYC Embedded 3251?
The EPYC Embedded 3151 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. Buy the EPYC Embedded 3251 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: l3 cache, pcie lanes, core architecture, socket and memory type are identical here. They match on 6 further specifications as well.
Frequently asked questions
Is the Security Processor the same on the EPYC Embedded 3151 and EPYC Embedded 3251?
It is. Both are listed at Yes, so it is not a reason to pick one over the other.
