Much newer manufacturing process 22 nm vs 90 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
Higher clock speed 3.4 GHz vs 3 GHz Around 15% higher clock speed
Significantly lower typical power consumption 107.5W vs 134.06W Around 20% lower typical power consumption
Much better overclocked clock speed (Air) 4.59 GHz vs 3 GHz Around 55% better overclocked clock speed (Air)
Newer Apr, 2012 vs Nov, 2005 Release date over 6 years later
More cores 4 vs 2 Twice as many cores; run more applications at once
Much better overclocked clock speed (Water) 4.71 GHz vs 3 GHz More than 55% better overclocked clock speed (Water)
Much lower annual commercial energy cost 106 $/year vs 144.54 $/year More than 25% lower annual commercial energy cost
