Report a correction
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
Significantly newer manufacturing process 22 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better turbo clock speed 854 MHz vs 566 MHz More than 50% better turbo clock speed
Lower typical power consumption 6.09W vs 20.31W 3.3x lower typical power consumption
More cores 4 vs 2 Twice as many cores; run more applications at once
Newer Feb, 2014 vs Jan, 2010 Release date over 4 years later
Higher GPU clock speed 313 MHz vs 266 MHz Around 20% higher GPU clock speed
Lower annual home energy cost 1.81 $/year vs 6.02 $/year 3.3x lower annual home energy cost
Lower annual commercial energy cost 6.57 $/year vs 21.9 $/year 3.3x lower annual commercial energy cost
