AMD · EPYC 4005 · 2025 · AM5
The AMD EPYC 4565P is a server processor with 16 cores, released in 2025 at an MSRP of $589. It is part of the EPYC 4005 lineup, using the EPYC 4005 platform, and fits the AM5 socket. Internally, it is built on the "Zen 5" architecture. Thanks to AMD Simultaneous Multi-Threading (SMT), each core can handle two instruction streams simultaneously, yielding a total of 32 threads for improved parallelism. The EPYC 4565P has a base clock of 4.3 GHz and can boost up to 5.7 GHz depending on workload and thermal headroom. AMD manufactures the "Zen 5" silicon on a TSMC 4nm process node. This processor supports DDR5 memory across 2 channels, up to 256GB total, with ECC support standard for data integrity in server workloads. It supports single-socket (1P) configurations, with 28 lanes of PCIe 5.0 available for storage, networking and accelerators. With a TDP of 170W, the EPYC 4565P runs hot and requires a capable cooling setup. The cache hierarchy consists of 80KB/core of L1, 1MB/core of L2, and 64MB of L3 cache — a substantial cache pool well suited to memory-bound enterprise and virtualization workloads.
A lower-cache Grado variant with 64MB L3 versus the 4585PX's 128MB, at the same core count and clock speed — positioned as the more affordable entry point into AMD's AM5-based single-socket EPYC 4005 lineup.
