Technical Analysis
Detailed breakdown of Xeon E5-1660 specifications and capabilities.
Processing Power
The Xeon E5-1660 is a 6-core / 12-thread processor based on the Sandy Bridge-E (2011−2013) architecture, manufactured on a 32 nm process node. It reaches a maximum boost clock of 3.9 GHz from a base frequency of 3.3 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. With a massive 15360 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 8,324, placing it in the Budget performance tier as a Legacy generation product.
