AMD EPYC Embedded 3151 vs AMD EPYC Embedded 3255: Comparison
EPYC Embedded 3151 vs EPYC Embedded 3255 boost clock compared
Boost clock is the dividing line, EPYC Embedded 3151 2.9 GHz against EPYC Embedded 3255 3.1 GHz. Tdp is not the same on both, 45 W on the EPYC Embedded 3151 versus 25-55W on the EPYC Embedded 3255. EPYC Embedded 3255 also leads on l2 cache, 2 MB on the EPYC Embedded 3151 versus 4 MB on the EPYC Embedded 3255. They differ on core count too, 4 cores on the EPYC Embedded 3151 versus 8 cores on the EPYC Embedded 3255. Thread count is not the same on both, 8 threads on the EPYC Embedded 3151 versus 16 threads on the EPYC Embedded 3255. They differ on base clock too, 2.7 GHz on the EPYC Embedded 3151 versus 2.5 GHz on the EPYC Embedded 3255. They differ on junction temp range too, 0-95°C on the EPYC Embedded 3151 versus -40-105°C on the EPYC Embedded 3255.
EPYC Embedded 3151 vs EPYC Embedded 3255: which one fits your build
The EPYC Embedded 3151 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 3255 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
Where they agree, they agree completely, l3 cache, pcie lanes, core architecture, socket and memory type included, so the decision does not turn on any of those. They match on 6 further specifications as well.
Frequently asked questions
