Intel is near launching a trio of new Core i5 and i7 processors that all push into new territory, a series of leaks have shown. One slip suggests that the company will launch the Core i7-875K in early June. The quad-core, likely 3.33GHz chip would be the first Nehalem-based processor with an unlocked clock frequency and would be tailored to hobbyists. While overclocking has been possible before, the move would let experienced users change the clock speed directly instead of modifying the bus speed and voltage.
