A leaked document from Intel lets us know there is a new top-end unlocked LGA1155 processor coming soon. It is the Core i7-2700K, of which the leaked document indicated its box part product code to be BX80623I72700K and carrying a spec code of SR0DG.
Official details on the chip in terms of clock rate etc. were not disclosed, but it can be easily assumed that given the i5-2000 and i7-2000 series are spaced in steps of 100MHz, the i7-2700K will likely come in at 3.5GHz with 3.9GHz Turbo Boost.
We still await a definitive release date for it, but it's quite possible Intel is planning to hit the market with it when AMD lets loose its first batch of FX processors, displacing the existing COre i7-2600K's price point and making it more competitive with the FX 8150 in particular.
