Reasons to consider the
Intel Core i3 3220

Report a correction
Significantly higher clock speed 3.3 GHz vs 2.33 GHz More than 40% higher clock speed
Much newer manufacturing process 22 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Significantly better overclocked clock speed (Air) 3.43 GHz vs 2.33 GHz More than 45% better overclocked clock speed (Air)
Newer Sep, 2012 vs Feb, 2008 Release date over 4 years later
Lower typical power consumption 44.69W vs 52.81W More than 15% lower typical power consumption
More threads 4 vs 2 Twice as many threads
Significantly better overclocked clock speed (Water) 3.46 GHz vs 2.33 GHz Around 50% better overclocked clock speed (Water)
Lower annual home energy cost 13.25 $/year vs 15.66 $/year More than 15% lower annual home energy cost
Lower annual commercial energy cost 48.18 $/year vs 56.94 $/year More than 15% lower annual commercial energy cost
