Technical Analysis
Detailed breakdown of Xeon E3-1285 v3 specifications and capabilities.
Processing Power
The Xeon E3-1285 v3 is a 4-core / 8-thread processor based on the Haswell-WS (2013−2014) architecture, manufactured on a 22 nm process node. It reaches a maximum boost clock of 4 GHz from a base frequency of 3.6 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. With a massive 8192 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 7,211, placing it in the Entry Level performance tier as a Legacy generation product.
