AMD EPYC 8025P vs AMD EPYC 8434P: Comparison
What is the difference between EPYC 8025P and EPYC 8434P?
L3 cache is where these two genuinely part company, EPYC 8025P 64 MB against EPYC 8434P 128 MB, a 50% lead for EPYC 8434P. SPECrate® 2017 Integer (base), 1-chip backs the spec sheet up. EPYC 8434P scores 423 to 117, 72% clear. Add memory bandwidth to that, 307 GB/s on the EPYC 8025P versus 230.4 GB/s on the EPYC 8434P, and the pattern holds. There is a split on product family as well, EPYC 8005 Series on the EPYC 8025P versus EPYC 8004 Series on the EPYC 8434P. There is a split on release year as well, 2026 on the EPYC 8025P versus 2023 on the EPYC 8434P. They differ on core count too, 8 cores on the EPYC 8025P versus 48 cores on the EPYC 8434P. Thread count is not the same on both, 16 threads on the EPYC 8025P versus 96 threads on the EPYC 8434P.
EPYC 8025P vs EPYC 8434P: which one fits your build
The EPYC 8025P suits datacenter and cloud compute and virtualization-dense server workloads, though it is the wrong buy for consumer desktop builds and single-threaded latency-sensitive workloads on lower core-count SKUs. The EPYC 8434P is the one to take for datacenter and cloud compute and virtualization-dense server workloads, though it is not the pick for consumer desktop builds and single-threaded latency-sensitive workloads on lower core-count SKUs.
What EPYC 8025P and EPYC 8434P have in common
Where they agree, they agree completely, memory channels, pcie lanes, cpu socket, segment and smt support included, so the decision does not turn on any of those. They match on 5 further specifications as well.
Frequently asked questions
Do the EPYC 8025P and EPYC 8434P differ on boost clock?
Yes. Boost Clock reads 4.5 GHz on the EPYC 8025P versus 3.1 GHz on the EPYC 8434P.
Is the Multi-Socket Support the same on the EPYC 8025P and EPYC 8434P?
It is. Both are listed at Single Socket Only, so it is not a reason to pick one over the other.
