Intel introduces Xeon E3-1200 CPUs
Apr 03, 2011: Intel Xeon E3-1200 server processors for single-CPU workstations and entry-level servers were added today to official Intel price-list. This update confirms earlier reports of the Xeon E3 family launch, planned for the next week. The first details of the Intel E3-1200 microprocessors emerged last October, and, as we can tell from the brief specs in the price list, they stayed without changes. Xeon E3 launch date, though, was delayed by a few weeks due to a SATA ports defect, discovered in January in Series 6 "Cougar Point" chipsets.



Dell announces PowerEdge C5000 microserver series
Mar 24, 2011: On March 22 Dell announced PowerEdge C5000 generation of servers, that combine energy efficiency with high-density form factor. New products pack up to 12 nodes, or "micro-servers", in a 3U chassis, and each node can be used as a dedicated server for lightweight web-based applications. Dedicated systems of these type don't require large amounts of memory, and can be powered by single CPU. Dell plans to offer two separate micro-server models - C5125, based on AMD low- and mid-power microprocessors, and C5220, that uses low- and standard voltage CPUs from forthcoming Xeon E3-1200 family.



Intel Xeon E3 microprocessors will launch on February 20
Feb 07, 2011: If you followed recent Intel announcements, you know that Intel is planning to release large number of mid-class desktop and mobile dual-core microprocessors this February. Based on information from Intel ARK database, the launch date was set to February 20. Recent discovery of a problem with Serial ATA 3 Gb/s ports in the Cougar Point chipsets may delay the launch, but we don't have a definitive information regarding this matter. We do have information on hand that on February 20 Intel also planned to introduce 12 models from Xeon E3 microprocessor series, and three C200-series chipsets: C202, C204 and C206.



Part numbers and prices for Xeon E3-1200 series CPUs
Jan 18, 2011: Yesterday Intel posted Material declaration data sheets for upcoming Xeon E3-1200 series microprocessors. As a part of these declarations, they exposed box part numbers and S-Spec numbers of standard-power Xeon CPUs. The published information confirmed model numbers of E3-1200-series processors, that were revealed for the first time in October of last year.



Partial specs of Intel C202, C204 and C406 server chipsets
Nov 01, 2010: Earlier this month, we published specifications of upcoming Xeon E3-1200 series microprocessors. At the time, we knew that Xeons will be paired with Intel C206 chipset, but didn't have any details of it. Recently, we learned that the Xeon E3-1200 CPUs will be supported not by one, but by three slightly different chipsets - C202, C204 and C206, and we also found their partial specifications.



Intel prepares Xeon E3-1200 series processors
Oct 06, 2010: Earlier today we revealed Intel's plans to release new version of Xeon microprocessor for single-socket workstations. The W3690 is not the only one-way Xeon that we can expect at the beginning of 2011. In the first quarter Intel is going to replace most of Xeon 3400-series CPUs with new E3-1200 series, based on Sandy Bridge microarchitecture. Intel Xeon E3-1200 lineup consists of 11 low- and standard-power microprocessors with core frequencies ranging from 2.2 GHz to 3.5 GHz.
