AMD EPYC 4345P Server Processor

The AMD EPYC 4345P is an 8-core, 16-thread server CPU built on the EPYC 4005 Series platform for Socket AM5. It targets small business servers and hosted IT services that need dependable performance, energy efficiency and built-in security features at an accessible acquisition cost.

DDR5 5600 Memory Interface

The integrated memory controller supports DDR5 at 5600 MT/s, defining the practical memory speed ceiling for this processor. System memory bandwidth and capacity are limited by this controller specification and the motherboard implementation, so workloads requiring faster memory clocks or larger supported capacities must look beyond this platform.

8-Core 65W Thermal Envelope

With a base clock of 3.8 GHz and a maximum boost up to 5.5 GHz, the 65W TDP provides comfortable headroom for everyday server workloads and all-day processing within compact, power-constrained chassis. Sustained heavy multi-threaded loads or applications demanding higher core counts will reach the limits of this thermal and core budget.

Questions about this item

Should I pick the 8-core 4345P or a 16-core EPYC 4005 model?

The 4345P has 8 cores and 16 threads at 65 W, suited for lighter workloads; the 16-core 4005 series parts offer twice the threads for heavier multi-threaded tasks.

What does the 5.5 GHz boost clock deliver in a real server?

Single-thread bursts reach 5.5 GHz while the 3.8 GHz base sustains steady throughput across all 8 cores within the 65 W envelope.

How does the DDR5 5600 memory controller limit RAM speed?

The integrated controller runs DDR5 at 5600 MT/s; faster modules will downclock to this speed.
