Report a correction
Much higher clock speed 3.4 GHz vs 1.4 GHz Around 2.5x higher clock speed
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Significantly newer manufacturing process 14 nm vs 22 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better overclocked clock speed (Air) 3.98 GHz vs 1.4 GHz More than 2.8x better overclocked clock speed (Air)
More threads 8 vs 2 6 more threads
Slightly more l3 cache 8 MB vs 6 MB Around 35% more l3 cache; more data can be stored in the l3 cache for quick access later
More cores 4 vs 2 Twice as many cores; run more applications at once
Much better overclocked clock speed (Water) 4.18 GHz vs 1.4 GHz Around 3x better overclocked clock speed (Water)
Newer Jul, 2015 vs Jan, 2014 Release date over 1 years later
