Technical Analysis
Detailed breakdown of Core i5-2550K specifications and capabilities.
Processing Power
The Core i5-2550K is a 4-core / 4-thread processor based on the Sandy Bridge (2011−2013) architecture, manufactured on a 32 nm process node. It reaches a maximum boost clock of 3.8 GHz from a base frequency of 3.4 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. With a massive 6144 kB (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 256 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 4,228, placing it in the Entry Level performance tier as a Legacy generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 707, while multi-core reaches 2,010. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 4,058.
