Reasons to consider the
Intel Core i5 4278U

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
Significantly higher clock speed 2.6 GHz vs 1.6 GHz Around 65% 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 22.75W vs 84.5W 3.7x lower typical power consumption
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Newer Jul, 2014 vs Oct, 2007 Release date over 6 years later
Much lower annual home energy cost 6.75 $/year vs 25.05 $/year 3.7x lower annual home energy cost
Much lower annual commercial energy cost 24.53 $/year vs 91.1 $/year 3.7x lower annual commercial energy cost
