Detailed breakdown of Ryzen 7 7840S specifications and capabilities.
Processing Power
The Ryzen 7 7840S is a 8-core / 16-thread processor based on the Phoenix-HS (Zen 4) (2023) architecture, manufactured on a 4 nm process node. It reaches a maximum boost clock of 5.1 GHz from a base frequency of 3.8 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 16 MB of L3 cache, plus 8 MB of L2 cache and 512 kB of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 23,290, placing it in the Mid-Range performance tier as a Recent generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 2,570, while multi-core reaches 13,535. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 13,500.
