AMD EPYC 4565P 16c/32t 4.3GHz-5.7GHz 170W (100-000001559)

AMD EPYC 4565P Server CPU

Positioning and target workloads

AMD EPYC 4565P is a 16-core, single-socket server processor from the EPYC 4005 generation, based on Zen 5 CPU cores for the AM5 platform. It represents the highest-performance SKU in this family, designed for scenarios where maximum per-core speed and strong parallel capacity are both required within a modern single-socket server.

Core architecture, frequency profile, and cache behavior

The processor delivers 16 cores and 32 threads with a 4.3 GHz base frequency and boost clocks reaching up to 5.7 GHz. Zen 5 architectural improvements increase instructions-per-clock and execution efficiency, enabling sustained high performance across mixed workloads. With 64 MB of L3 cache, EPYC 4565P reduces memory access latency for application servers, microservices platforms, and performance-oriented virtualization environments. The 170 W TDP reflects its performance-focused design and requires appropriate server-grade cooling.

Memory subsystem and performance planning

EPYC 4565P supports dual-channel DDR5 memory at speeds up to DDR5-5600. High memory frequency provides substantial bandwidth per channel, complementing the processor’s high clock and core density. Balanced DIMM population and capacity planning aligned with workload locality are essential for optimal performance.

PCIe Gen 5 connectivity and I/O strategy

The processor exposes up to 28 PCI Express Gen 5 lanes, enabling direct attachment of next-generation NVMe storage and high-speed network adapters. Some lanes may be allocated to a chipset to expand connectivity, so careful lane planning is recommended for performance-oriented system designs.

Platform-level features for professional environments

EPYC 4565P integrates AMD’s Secure Processor for hardware-based security features. Integrated graphics support for basic console access is available depending on motherboard implementation. The AM5 platform also provides modern board-level connectivity and long-term platform support.

Ideal deployment scenarios

This CPU is well suited for performance-sensitive application servers, low-latency databases, CI/CD and compilation workloads, high-density container platforms, and virtualization hosts running demanding workloads. EPYC 4565P is an effective choice when maximum performance within a single-socket, Zen 5–based platform is required.
