Reasons to consider the
Intel Core i7 6700K

Report a correction
Much higher clock speed 4 GHz vs 1.24 GHz Around 3.2x higher clock speed
Much higher turbo clock speed 4.2 GHz vs 1.33 GHz Around 3.2x higher turbo clock speed
Is unlocked Yes vs No Somewhat common; An unlocked multiplier allows for easier overclocking
Much lower typical power consumption 73.94W vs 219.38W 3x lower typical power consumption
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much better overclocked clock speed (Air) 4.61 GHz vs 1.24 GHz Around 3.8x better overclocked clock speed (Air)
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Significantly newer manufacturing process 14 nm vs 22 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much lower annual home energy cost 21.92 $/year vs 65.04 $/year 3x lower annual home energy cost
Much lower annual commercial energy cost 79.72 $/year vs 236.52 $/year 3x lower annual commercial energy cost
Much better overclocked clock speed (Water) 4.77 GHz vs 1.24 GHz More than 3.8x better overclocked clock speed (Water)
Newer Jul, 2015 vs Jan, 2014 Release date over 1 years later
