SB-E: Enthusiast Full 8 Core Dual Socket Monsters On The Way Early 2012

The latest Sandy Bridge-E 6 core processors have just been released, to excellent reviews. However, the architecture is designed for 8 cores, so these current i7-3960X & i7-3930K processors actually contain those 8 cores, but with two turned off in order to enable them to fit within a manageable 130 W power envelope. Hence there's quite a bit more potential to be released and soon. Therefore, anyone looking to invest in the premium-priced SB-E platform right now, should note that these processors are at the initial C1 stepping and have the VT-d hardware virtualization issue and PCI-E 3.0 compatibility uncertainty. The VT-d problem will be a real show stopper where hardware acceleration of a virtual machine is a must, so it shouldn't be ignored.

VR-ZONE brings us news that the fully unlocked SB-E 8 core chips will be released as the long awaited Xeon E5 family of processors, which will be built on the C2 stepping, solving the above issues. However, being 8 core, these will be very power hungry indeed, consuming around 150 W at just 3 GHz with all 8 cores active and 20 MB of L3 cache. At 2.5 GHz though, the new processors are expected to fit within the 95 W power envelope.
Being "Xeon" processors, they are primarily intended to be used in multi-socket configurations in servers and very high end desktops for businesses that need this kind of raw power. Of course, the other market that these E5 processors are aimed at, are the hardcore PC enthusiasts who have very deep pockets and want the ultimate power in their desktops at any price. It's rumoured that such people might be using these powerhouse systems for more than just playing Sudoku, doing a bit of word processing and browsing the internet, but these are unconfirmed at the time of publication.

Later on in 2012, Ivy Bridge-E is expected to be released, which will be an optical shrink of SB-E, while also using Intel's new 22 nm tri-gate transistors. This will bring significant performance improvements, including an increase to 10 cores and 25 MB L3 cache. TechPowerUp has more details on this generation, here. So, with these new high wattage processors eventually becoming more mainstream, could we see the return of the ill-fated BTX (Balanced Technology Extended) form factor case, introduced by Intel around seven years ago? Only time will tell.

the performance is good but with high power consuption it may result higher temp
