AMD EPYC 4545P 16c/32t 3.0GHz-5.4GHz 65W (100-000001764)

AMD EPYC 4545P Server CPU

Positioning and target workloads

AMD EPYC 4545P is a 16-core, single-socket server processor from the EPYC 4005 generation, built on Zen 5 CPU cores and designed for the AM5 platform. It is positioned as a high-density option for professional environments that require more parallel capacity than 12-core models while staying within a relatively efficient power envelope.

Core architecture, frequency profile, and cache behavior

The processor provides 16 cores and 32 threads with a base frequency of 3.0 GHz and boost clocks up to 5.4 GHz. Zen 5 cores deliver higher instructions-per-clock and improved execution efficiency, enabling strong multi-threaded throughput with competitive single-thread performance. With 64 MB of L3 cache, EPYC 4545P supports larger shared working sets and reduces memory access latency in concurrent server workloads. The 65 W TDP allows deployment in compact server chassis without aggressive cooling.

Memory subsystem and capacity planning

EPYC 4545P supports dual-channel DDR5 memory at speeds up to DDR5-5600. Higher memory frequency improves effective bandwidth per core, which aligns well with Zen 5 execution capability. Balanced DIMM population and capacity planning based on workload locality are recommended for consistent performance.

PCIe Gen 5 connectivity and I/O design

The processor exposes up to 28 PCI Express Gen 5 lanes, enabling direct attachment of high-speed NVMe storage and modern network adapters. Some lanes may be allocated to a chipset to extend connectivity, so careful lane planning is advised for compact and edge-focused server designs.

Platform-level features for enterprise environments

EPYC 4545P integrates AMD’s Secure Processor for hardware-rooted security features. Integrated graphics support for basic console access is available depending on motherboard implementation, simplifying deployment and management. The AM5 platform also enables modern board-level connectivity and long-term support.

Ideal deployment scenarios

This CPU is well suited for container orchestration nodes, application and middleware servers with high concurrency, CI/CD systems, virtualization hosts with higher consolidation ratios, and edge servers leveraging PCIe Gen 5 storage and networking. EPYC 4545P is an effective choice when Zen 5 efficiency and modern I/O are required within a low-power, single-socket platform.
