Much newer manufacturing process 32 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much lower typical power consumption 28.44W vs 105.63W 3.7x lower typical power consumption
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Supports dynamic frequency scaling Yes vs No Somewhat common; Allows for maximum performance when needed, while conserving power and minimizing heat production when not needed
Much better performance per dollar 0.56 pt/$ vs 0.06 pt/$ More than 8.8x better performance per dollar
Newer Sep, 2010 vs Dec, 2005 Release date over 4 years later
Significantly better performance per watt 3.58 pt/W vs 0.49 pt/W More than 7.2x better performance per watt
Much lower annual home energy cost 8.43 $/year vs 31.32 $/year 3.7x lower annual home energy cost
Much lower annual commercial energy cost 30.66 $/year vs 113.88 $/year 3.7x lower annual commercial energy cost
Better PassMark (Single core) score 1,070 vs 796 Around 35% better PassMark (Single core) score
Better PassMark score 2,335 vs 905 More than 2.5x better PassMark score
