AMD EPYC 8325P vs AMD EPYC 8434PN: Comparison
EPYC 8325P vs EPYC 8434PN l3 cache compared
On l3 cache the spread is 50%, EPYC 8325P 256 MB against EPYC 8434PN 128 MB, so EPYC 8325P takes it. Measured rather than claimed: in SPECrate® 2017 Integer (base), 1-chip the EPYC 8325P returns 418 against 406, a 3% lead. Memory bandwidth runs the same way, 307 GB/s on the EPYC 8325P versus 230.4 GB/s on the EPYC 8434PN, another win for EPYC 8325P. Release year is not the same on both, 2026 on the EPYC 8325P versus 2023 on the EPYC 8434PN. There is a split on core count as well, 32 cores on the EPYC 8325P versus 48 cores on the EPYC 8434PN. Thread count is not the same on both, 64 threads on the EPYC 8325P versus 96 threads on the EPYC 8434PN. Core architecture is not the same on both, Zen 5 on the EPYC 8325P versus Zen 4c on the EPYC 8434PN.
EPYC 8325P vs EPYC 8434PN: which one fits your build
Buy the EPYC 8325P for 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 8434PN is the one to take for datacenter and cloud compute and virtualization-dense server workloads, though it is not built for consumer desktop builds and single-threaded latency-sensitive workloads on lower core-count SKUs.
Where the two are identical
Everything else lines up. Memory channels, pcie lanes, cpu socket, segment and smt support read the same on both, so those are not worth weighing. They match on 5 further specifications as well.
Frequently asked questions
Do the EPYC 8325P and EPYC 8434PN differ on boost clock?
Yes. Boost Clock reads 4.5 GHz on the EPYC 8325P versus 3 GHz on the EPYC 8434PN.
Is the Multi-Socket Support the same on the EPYC 8325P and EPYC 8434PN?
It is. Both are listed at Single Socket Only, so it is not a reason to pick one over the other.

Which one should you pick?
Choose 8325P if you want the higher L3 cache (256 MB vs 128 MB), the higher memory channels (6 channels vs 6 channels) and the higher PCIe lanes (96 lanes vs 96 lanes).
Choose 8434PN if you already have it on hand or find it at a lower price.
