Intel updated its socket LGA-1366 Xeon processor portfolio with the W3565. Based on the Nehalem architecture, this quad-core processor is made for single-socket servers and workstations. It has near-identical specifications to the consumer-grade Core i7 960, in having a clock speed of 3.20 GHz (24 x 133 MHz), 8 MB of L3 cache, and a QuickPath Interconnect (QPI) speed of 4.8 GT/s. The QPI speed is perhaps the only thing that differentiates it from the W3570, which has the same clock speed, albeit a QPI speed of 6.4 GT/s. This one specification makes for a large price difference. While the new W3565 is priced at $562, the W3570 is priced at $999. With the introduction of the new processor, Intel is set to retire the 2.93 GHz W3540, and 3.06 GHz W3550.
