Report a correction
Much newer manufacturing process 45 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better performance per dollar 14.05 pt/$ vs 1.26 pt/$ Around 11.2x better performance per dollar
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
Higher clock speed 3 GHz vs 2.8 GHz More than 5% higher clock speed
Lower typical power consumption 52.81W vs 77.19W More than 30% lower typical power consumption
Significantly more l2 cache per core 1 MB/core vs 0.5 MB/core 2x more l2 cache per core
Better PassMark (Single core) score 1,232 vs 936 More than 30% better PassMark (Single core) score
Newer Jul, 2010 vs Apr, 2009 Release date over 1 years later
Lower annual commercial energy cost 56.94 $/year vs 83.22 $/year More than 30% lower annual commercial energy cost
Lower annual home energy cost 15.66 $/year vs 22.89 $/year More than 30% lower annual home energy cost
