AMD® EPYC™ 8125P

The AMD EPYC 8125P is a server processor with 16 cores and 32 threads, built on the Zen 5 architecture (4 nm process). It launched in May 2026. Clocks run from 2.65 GHz base to 4.5 GHz boost. A 128-MB L3 cache backs the cores (9.0 MB per core). It supports DDR5 memory. The chip drops into the SP6 socket and exposes PCIe 5.0 (96 lanes). Rated TDP is 125 W.

The AMD EPYC 8125P has 16 physical cores and runs 32 logical threads. It runs 2 threads per core. It runs at a base clock of 2.65 GHz and boosts up to 4.50 GHz.

The AMD EPYC 8125P is a server processor, belongs to the AMD EPYC family, uses the Zen 5 architecture and is manufactured on a 4 nm process. It launched in May 2026.

The AMD EPYC 8125P has 16 MB of L2 cache and 128 MB of L3 cache. That adds up to about 144.0 MB of cache, or 9.00 MB per core. Each core has 1 MB of private L2 cache. Feex has no recorded L1 cache size for this processor.

The AMD EPYC 8125P has a 2-level cache hierarchy: L2 at 16 MB and L3 at 128 MB. L3 is the largest level and makes up about 89% of the cache listed here.

The AMD EPYC 8125P supports DDR5 memory, uses 6 memory channels, runs memory at up to 6,400 MT/s and delivers up to 307.2 GB/s of memory bandwidth. It does not support DDR4 and LPDDR memory.

The AMD EPYC 8125P does not include integrated graphics, so a discrete graphics card is required for display output.

The AMD EPYC 8125P uses the SP6 socket, supports PCI Express 5.0 and provides up to 96 PCIe lanes.

The AMD EPYC 8125P has a rated TDP of 125 W.
