According to preliminary tests, the quad-core Core i7-3820 with 10 MB cache in the third level and default frequency 3.6 GHz on its speed is comparable to the Core i7-2600K.
Associates reported that the announcement of processor Core i7-3820 (3.6/3.9 GHz) LGA 2011 is scheduled for 13 February. Four cores are combined with 10 MB cache in the third level, supported by four-channel memory. Formally, this processor has a limited increase in the multiplier, but the available options for overclocking LGA 2011 platform should be sufficient for the conquest of 5.5 GHz.
The cost of CPU Core i7-3820 would be $ 285. This is the cheapest Sandy Bridge-E, but the cost of motherboard with LGA 2011 and quad memory kit is high enough.
