Reasons to consider the
Intel Core i3 3220

Report a correction
Much newer manufacturing process 22 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Higher clock speed 3.3 GHz vs 2.6 GHz More than 25% higher clock speed
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much lower typical power consumption 44.69W vs 77.19W More than 40% lower typical power consumption
Significantly more l3 cache per core 1.5 MB/core vs 0.5 MB/core 3x more l3 cache per core
