Reasons to consider the
Intel Core i7 3770S

Report a correction
Significantly higher clock speed 3.1 GHz vs 2 GHz More than 55% higher clock speed
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Supports dynamic frequency scaling Yes vs No Somewhat common; Allows for maximum performance when needed, while conserving power and minimizing heat production when not needed
Significantly newer manufacturing process 22 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Much better overclocked clock speed (Air) 3.73 GHz vs 2 GHz More than 85% better overclocked clock speed (Air)
More cores 4 vs 2 Twice as many cores; run more applications at once
More threads 8 vs 4 Twice as many threads
Much better overclocked clock speed (Water) 3.9 GHz vs 2 GHz 95% better overclocked clock speed (Water)
