Report a correction
Much newer manufacturing process 22 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Significantly more l2 cache 2 MB vs 1 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Significantly lower typical power consumption 6.09W vs 28.44W 4.7x lower typical power consumption
Much better performance per watt 7.82 pt/W vs 2.4 pt/W More than 3.2x better performance per watt
Newer Jul, 2014 vs Oct, 2008 Release date over 5 years later
More cores 4 vs 2 Twice as many cores; run more applications at once
More threads 4 vs 2 Twice as many threads
Significantly lower annual home energy cost 1.81 $/year vs 8.43 $/year 4.7x lower annual home energy cost
Significantly lower annual commercial energy cost 6.57 $/year vs 30.66 $/year 4.7x lower annual commercial energy cost
