News


Mar 07, 2012: Intel yesterday introduced Romley server platform for single- and dual-socket workstations and servers. The platform is going to replace Tylersburg platform with Xeon 5600 series processors, that were on the market since March 2010. Yesterday's launch included C600 series "Patsburg" chipset, and Xeon E5-1600 or E5-2600 chips, based on "Sandy Bridge-EP" core, and utilizing socket R (socket 2011). More Xeon E5 microprocessors are expected in the second quarter, when the Romley platform will be expanded with E5-2400 and E5-4600 CPUs.



Oct 27, 2011: In the first half of 2012 Intel will introduce Xeon E5 server chips for single-, dual-core and quad-processor servers. The first two E5 families, coming in Q1 2012, are E5-1600 and E5-2600 series for socket 2011 platform. We already published CPU line-ups for both E5 subfamilies, and we reported on Xeon E5-1600 launch prices. We also recently learned about Xeon E5-2600 prices.



Oct 10, 2011: Last week there were plenty of news stories regarding soon to be released AMD server microprocessors, built on "Bulldozer" micro-architecture. As you may know, Intel also planned to introduce new server processors, branded as Xeon E5, in the fourth quarter. In September, during Intel Developer Forum event in San Francisco, new information came to light implying that Xeon E5 launch is postponed until the first quarter 2012.



Aug 26, 2011: In July we disclosed details of Xeon E5-1600 family of server-class microprocessors, designed for one-way servers and high-performance workstations. Processors from this family are part of Romley-WS platform, which is coming in the next quarter. The CPUs are based on 32nm Sandy Bridge-EP core, and they utilize socket R (socket 2011). Also in the 4th quarter, Intel will launch Romley-EP dual-socket platform, consisting of 17 different E5-2600 models and C600-series chipset.
