Reasons to consider the
Intel Core i3 3220

Report a correction
Much more l3 cache 3 MB vs 0.5 MB 6x more l3 cache; more data can be stored in the l3 cache for quick access later
Much 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 159W 3.6x lower typical power consumption
Much newer manufacturing process 22 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better performance per watt 2.69 pt/W vs 0.73 pt/W Around 3.8x better performance per watt
Much more l3 cache per core 1.5 MB/core vs 0.13 MB/core 12x more l3 cache per core
Much lower annual home energy cost 13.25 $/year vs 59.83 $/year 4.5x lower annual home energy cost
Much lower annual commercial energy cost 48.18 $/year vs 153.3 $/year 3.2x lower annual commercial energy cost
Much better overclocked clock speed (Water) 3.46 GHz vs 2.6 GHz Around 35% better overclocked clock speed (Water)
Newer Sep, 2012 vs Sep, 2009 Release date over 3 years later
