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.
Prices of Xeon E5-2600-series 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.
Launch schedule of Intel Xeon E5 microprocessors
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.
Intel to launch Xeon E5-2600 series in Q4 2011
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.
