Reasons to consider the
Intel Core i5 650

Report a correction
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
Higher clock speed 3.2 GHz vs 3 GHz More than 5% higher clock speed
Much better overclocked clock speed (Air) 4.31 GHz vs 3.56 GHz More than 20% better overclocked clock speed (Air)
Much better overclocked clock speed (Water) 5.08 GHz vs 3 GHz Around 70% better overclocked clock speed (Water)
Higher Maximum operating temperature 72.6 °C vs 71 °C Almost the same
