Intel Xeon E7 microprocessors to launch next week
Apr 03, 2011: As we already reported today, Intel updated price-list with new Xeon E3 microprocessors. In addition to that, 18 models from Xeon E7-2800, E7-4800 and E7-8800 families were added to the list. The specifications and April 4th introduction date of E7 CPUs were revealed in January of this year. It seems that the processors will be launched on time, unlike Xeon E3 family, that was delayed by one and half months.

Intel Xeon E7 series is slated for Q2 2011
Feb 07, 2011: On January 21, we published an article describing two Xeon E7 microprocessors, which S-Spec and part numbers were spotted on Intel website. An anonymous visitor commented on the story, and posted details of the full E7-2800 and E7-2800 lines of processors, along with expected April 4 launch date. Today, we received an indirect confirmation of this date from two different sources (documents). One source, dated by December 2010, provides April 4 - May 13 launch date range, while more recent second source from January states that the Westmere-EX launch is on track for the second quarter 2011. One of the documents also lists a few upcoming CPUs from E7-8800 series. These are Xeon E7-8830, E7-8837, E7-8850, E7-8867L, E7-8860, and E7-8870.

Preliminary specifications of Intel Xeon E7 microprocessors
Jan 24, 2011: Three days ago we posted a story with part and S-spec numbers of two forthcoming Xeon E7 microprocessors. Today, an anonymous visitor added a comment to that story detailing full line-up of Xeon E7 models. Coincidentally, we discovered additional information about Xeon E7 CPUs, which mostly matches with the posted Xeon line-up.

Intel Xeon E7 processor numbers spotted
Jan 21, 2011: Thanks to Intel Material Declaration Data Sheet database, we recently learned about S-Spec and part numbers of Intel Core i5-2405S CPU, and Xeon E3-1200 series microprocessors. Today was another update of the MDDS database, which disclosed two processor numbers for forthcoming Xeon E7 family. These are Xeon E7-4830 and Xeon E7-4870.
