Technical Analysis
Detailed breakdown of EPYC 9655 specifications and capabilities.
Processing Power
The EPYC 9655 is a 96-core / 192-thread processor based on the Turin (2024) architecture, manufactured on a 4 nm process node. It reaches a maximum boost clock of 4.5 GHz from a base frequency of 2.6 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. With a massive 384 MB (total) L3 cache (3D V-Cache technology), this processor has a significant gaming advantage — the large cache drastically reduces memory latency in game engines., plus 1 MB (per core) of L2 cache and 80 kB (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 156,110, placing it in the Enthusiast performance tier as a Recent generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 2,830, while multi-core reaches 29,329.
