The Intel core i7-3820 is a 32nm processor with a 3.6GHz default clock and Turbo capabilities up to 3.9GHz. This CPU features 10MB of L3 cache and a new beefed up quad-channel DDR3-1600 memory interface which is theoretically capable of 51.2GB/s of bandwidth.
Compared to its main competition, the i7-2600K, the i7-3820 has about 10% higher idle and 20% higher CPU load power consumption. This is a significant increase, but one must keep in mind that the Sandy Bridge-E chip does have 25% more power-sucking L3 cache, a much larger integrated memory controller, and a revamped PCI-E controlller. The Intel Core i7-3820 is an excellent processor and an ideal choice for those who need the inherent bandwidth advantages of the LGA2011 platform. Source
