Technical Analysis
Detailed breakdown of Ryzen 9 PRO 7945 specifications and capabilities.
Processing Power
The Ryzen 9 PRO 7945 is a 12-core / 24-thread processor based on the Raphael (2023−2025) architecture, manufactured on a 5 nm process node. It reaches a maximum boost clock of 5.4 GHz from a base frequency of 3.7 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 64 MB (total) of L3 cache, plus 1 MB (per core) of L2 cache and 64 kB (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 46,828, placing it in the Enthusiast performance tier as a Recent generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 2,206, while multi-core reaches 16,832. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 28,905.
