Intel rolls out Xeon E5-1600 and E5-2600 CPUs
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.

Intel Xeon E5 CPUs surfaced on Intel website
Jan 07, 2012: Forthcoming Intel Xeon E5 family will be separated into 4 subfamilies, based on intended market. Xeon E5-4600 will support up to 4-way servers, E5-2400 and E5-2600 will target 2-way servers and workstations, and E5-1600 series will work in uni-processor systems. In the past months we reported on details of E5-1600, E5-2400 and E5-2400 families, whereas model lineup of E5-4600 family was not known up to this moment. Today Intel added Xeon E5 box part numbers and S-spec numbers to Material Declaration Data Sheets (MDDS) database. This addition confirmed processor numbers of one- and two-way Xeon E5 chips, and revealed E5-4600 processor numbers.
