Much more l2 cache 2 MB vs 0.25 MB 8x more l2 cache; more data can be stored in the l2 cache for quick access later
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Significantly newer manufacturing process 22 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Slightly higher clock speed 1.47 GHz vs 1.3 GHz Around 15% higher clock speed
More cores 4 vs 1 3 more cores; run more applications at once
Significantly better overclocked clock speed (Air) 2.27 GHz vs 1.4 GHz More than 60% 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
Lower typical power consumption 1.63W vs 8.13W 5x lower typical power consumption
More threads 4 vs 2 Twice as many threads
Newer Mar, 2014 vs Apr, 2012 Release date over 1 years later
Lower annual commercial energy cost 1.75 $/year vs 8.76 $/year 5x lower annual commercial energy cost
Lower annual home energy cost 0.48 $/year vs 2.41 $/year 5x lower annual home energy cost
