Processing Power

The Xeon X6550 is a 8-core / 16-thread processor, manufactured on a 45 nm process node. It reaches a maximum boost clock of 2.4 GHz from a base frequency of 2 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. With a massive 18 MB L3 Cache L3 cache (3D V-Cache technology), this processor has a significant gaming advantage — the large cache drastically reduces memory latency in game engines.. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 1,936, placing it in the Entry Level performance tier as a Legacy generation product.
