Still classified as a Core i7 chip, the Xeon W5590 runs six 2.4GHz cores with 12MB of shared Level 3 cache and and 256KB of Level 2 cache per core. Hyperthreading support enables two program threads to run on each core, meaning that the whole system effectively delivers 12 cores. Price details have not been announced, but Westmere is officially due out in the first half of 2010. [Electronista]
