AMD Ryzen 9 PRO 5945

The AMD Ryzen 9 PRO 5945 is a 12-core, 24-thread desktop processor designed for enterprise environments requiring strong multithreaded performance within tight power budgets. Built on a 7nm process for the AM4 platform, it operates at a 65W base power rating with clock speeds scaling from 3 GHz up to a maximum boost of 4.7 GHz. It is geared toward professional desktop workstations that need heavy multi-core processing capability without requiring high-end cooling systems.

Best for Enterprise workstations needing high multi-threaded compute in power-restricted Best for Small-form-factor builds that require high core counts under a 65W thermal budge

Pros

High 12-core and 24-thread configuration for intensive multi-threaded workloads
Low 65W power envelope minimizes thermal and cooling requirements
Generous 64 MB of L3 cache to support memory-heavy tasks

Cons

Lacks integrated graphics, necessitating a dedicated graphics card for display output
Multiplier is locked, preventing traditional processor overclocking
Uses the older AM4 platform socket

Intel Core i9 12900F
