Reasons to consider the
Intel Core i7 4790K

Report a correction
Much newer manufacturing process 22 nm vs 130 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 4 GHz vs 1.47 GHz Around 2.8x higher clock speed
Significantly more l2 cache 1 MB vs 0.25 MB 4x more l2 cache; more data can be stored in the l2 cache for quick access later
Much better PassMark (Single core) score 2,530 vs 419 More than 6x better PassMark (Single core) score
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Much better PassMark score 11,194 vs 268 More than 41.8x better PassMark score
Much better overclocked clock speed (Air) 4.63 GHz vs 2.11 GHz Around 2.2x better overclocked clock speed (Air)
More threads 8 vs 1 7 more threads
More cores 4 vs 1 3 more cores; run more applications at once
Much better overclocked clock speed (Water) 4.8 GHz vs 1.47 GHz More than 3.2x better overclocked clock speed (Water)
