Technical Analysis
Detailed breakdown of Xeon X5450 specifications and capabilities.
Processing Power
The Xeon X5450 is a 4-core / 4-thread processor based on the Harpertown (2007−2008) architecture, manufactured on a 45 nm process node. It reaches a maximum boost clock of 3 GHz from a base frequency of 3 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. With a massive 12 MB L2 Cache L3 cache (3D V-Cache technology), this processor has a significant gaming advantage — the large cache drastically reduces memory latency in game engines., plus 6 MB (total) of L2 cache and 64 kB (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 2,416, placing it in the Entry Level performance tier as a Legacy generation product.
