Reasons to consider the
Intel Core i3 540

Report a correction
Much higher clock speed 3.06 GHz vs 1.2 GHz More than 2.5x higher clock speed
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much newer manufacturing process 32 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
