Much more l2 cache 2 MB vs 0.5 MB 4x more l2 cache; more data can be stored in the l2 cache for quick access later
Significantly newer manufacturing process 14 nm vs 22 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better performance per dollar 2.39 pt/$ vs 1.95 pt/$ Around 25% better performance per dollar
More cores 4 vs 2 Twice as many cores; run more applications at once
Better overclocked clock speed (Air) 2.24 GHz vs 1.5 GHz Around 50% better overclocked clock speed (Air)
More l2 cache per core 0.5 MB/core vs 0.25 MB/core 2x more l2 cache per core
Newer Jan, 2015 vs Sep, 2013 Release date over 1 years later
