Socket AM5 server processor
The AMD EPYC 4545P is a 16-core, 32-thread server CPU built on the Zen 5 architecture for the AM5 platform. It targets single-socket deployments that need high core density within a 65 W thermal envelope. Integrated graphics are absent, so a discrete GPU or headless operation is required.
64 MB L3 cache
A 64 MB L3 cache feeds the 16 Zen 5 cores to reduce latency on memory-bound workloads. The integrated memory controller runs DDR5 at 5600 MT/s, and PCI Express 5.0 lanes are available for high-throughput storage or networking cards. Scalability is limited to one processor per system.
65 W TDP
Thermal design power is rated at 65 W, with a base frequency of 3.0 GHz and a maximum turbo of 5.4 GHz. The 5 nm manufacturing process helps keep power draw modest under sustained load. Cooling solutions must handle the rated dissipation without exceeding socket clearance limits.

Questions about this item
What does the 16-core, 32-thread count mean for a single-socket server?
The 16 cores and 32 threads let one Socket AM5 board handle many parallel workloads such as virtualization or database tasks without needing a second processor.
How does the DDR5 5600 memory controller and PCIe 5.0 interface affect real-world throughput?
The integrated controller runs DDR5 at 5600 MT/s and the CPU provides PCIe 5.0 lanes, so memory bandwidth and device I/O scale together for storage or GPU accelerators.
What cooler clearance and power delivery does the 65W AM5 package require?
A 65W TDP fits standard AM5 coolers and typical server VRM designs; the processor drops into the socket without extra mounting hardware.
