Intel Sandy Bridge-E CPUs to retire in September 2014
Mar 04, 2014: Intel's line of "Sandy Bridge-E" extreme CPUs was launched in Q4 2011, and consisted of i7-3930K and i7-3960X models. The processors had such innovated features as 6 Hyper-Threaded CPU cores, up to 15 MB of level 3 cache, and quad-channel memory controller, but on another side they were priced at premium and required new and expensive socket 2011 motherboards. The family was expanded with Core i7-3820K and i7-3970X SKUs in 2012, and replaced with Core i7-4xxx "Ivy Bridge-E" products last year.

Intel Core i7-3970X is available
Nov 12, 2012: Intel today released their fastest desktop microprocessor, Core i7-3970X. Designed for socket 2011 platform, the processor features slightly better performance than Core i7-3960X, thanks to 200 MHz higher operating frequency and 100 MHz higher maximum Turbo Boost frequency. Intel today also launched DX79SR desktop motherboard.

Oct 10, 2012: Intel plans to add new Core i7-3970X Extreme processor for socket 2011 platform in the forth quarter 2012. This information has been leaked in July along with processor specifications, and later it was confirmed by leaked roadmap slides. Another confirmation we received days ago, when we spotted Core i7-3970X, along with brief details of the chip, in the CPU support list for DX79SI motherboard on Intel website.

Details of upcoming Core i7 Extreme processors
Sep 11, 2012: After last week's introduction of new socket 1155 microprocessors, there is only one desktop Intel CPU left to launch this year. Core i7-3970X, which is a slightly faster version of i7-3960X, will be available later this quarter. In the past we reported on features of this CPU, and, once again, they were confirmed by slides, published by Bright Side of News. According to the slides, the new Intel extreme processor has 6 CPUs cores, and 15 MB L3 cache shared between the cores.

This is the brand new sealed retail version Intel Core i7 3970X Extreme Edition. I really like this CPU and I don't think I will use it to build a rig, most likely for collection. This is also the first Intel Core i7 CPU has TDP rates at 150W in this series.
