Reasons to consider the
Intel Core i3 3220

Report a correction
Much higher clock speed 3.3 GHz vs 1.4 GHz More than 2.2x higher clock speed
Significantly newer manufacturing process 22 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher GPU clock speed 650 MHz vs 350 MHz More than 85% higher GPU clock speed
More l2 cache 0.5 MB vs 0.25 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
