Reasons to consider the
Intel Core i7 4770

Report a correction
Much newer manufacturing process 22 nm vs 180 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 3.4 GHz vs 1.73 GHz More than 95% 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
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Much better PassMark (Single core) score 2,029 vs 503 More than 4x better PassMark (Single core) score
Much better performance per watt 10.41 pt/W vs 0.62 pt/W More than 16.8x better performance per watt
Much better PassMark score 9,523 vs 323 Around 29.5x better PassMark score
Much better overclocked clock speed (Air) 3.85 GHz vs 2.13 GHz More than 80% 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) 4.01 GHz vs 1.73 GHz More than 2.2x better overclocked clock speed (Water)
