To begin with, Core i7-4820K is expected to be priced at US $310, a whole $40 cheaper than a Core i7-4770K. This quad-core chip features 3.70 GHz clocks, 3.90 GHz maximum Turbo Boost, and 10 MB of L3 cache, 48 PCI-Express gen 3.0 lanes, and a quad-channel memory controller; compared to the 3.60 GHz clocks, 3.90 GHz Turbo Boost, 8 MB L3 cache, 24 PCI-Express gen 3.0 lanes, and a dual-channel memory controller. To its credit, the i7-4770K features higher IPC thanks to its more advanced micro-architecture. Socket LGA2011 motherboards, such as Intel's DX79TO can be had for as low as $150. Tempting offer there.
