Processing Power

The Ryzen 9 3900 is a 12-core / 24-thread processor based on the Matisse (Zen 2) (2019−2020) architecture, manufactured on a 7 nm, 12 nm process node. It reaches a maximum boost clock of 4.3 GHz from a base frequency of 3.1 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 64 MB of L3 cache, plus 512 kB (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 30,588, placing it in the High-End performance tier as a Legacy generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 1,713, while multi-core reaches 10,983. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 17,700.
