Report a correction
Significantly newer manufacturing process 14 nm vs 22 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Higher clock speed 1.9 GHz vs 1.7 GHz More than 10% higher clock speed
Slightly more l3 cache 6 MB vs 4 MB 50% more l3 cache; more data can be stored in the l3 cache for quick access later
Significantly better overclocked clock speed (Air) 2.7 GHz vs 1.7 GHz Around 60% better overclocked clock speed (Air)
More cores 4 vs 2 Twice as many cores; run more applications at once
Newer Oct, 2015 vs Jun, 2012 Release date over 3 years later
Significantly better overclocked clock speed (Water) 2.7 GHz vs 1.7 GHz Around 60% better overclocked clock speed (Water)
