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
Higher clock speed 1.33 GHz vs 1.06 GHz More than 25% higher clock speed
Significantly better turbo clock speed 646 MHz vs 500 MHz Around 30% better turbo clock speed
Higher GPU clock speed 311 MHz vs 166 MHz More than 85% higher GPU clock speed
Lower typical power consumption 1.79W vs 14.63W 8.2x lower typical power consumption
More cores 4 vs 2 Twice as many cores; run more applications at once
Newer Apr, 2014 vs Jan, 2010 Release date over 4 years later
Better overclocked clock speed (Air) 1.63 GHz vs 1.07 GHz More than 50% better overclocked clock speed (Air)
Better overclocked clock speed (Water) 1.83 GHz vs 1.07 GHz More than 70% better overclocked clock speed (Water)
Lower annual home energy cost 0.53 $/year vs 4.34 $/year 8.2x lower annual home energy cost
Lower annual commercial energy cost 1.93 $/year vs 15.77 $/year 8.2x lower annual commercial energy cost
