Report a correction
Significantly higher clock speed 3.5 GHz vs 2.53 GHz Around 40% higher clock speed
Much newer manufacturing process 22 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
More l3 cache 8 MB vs 4 MB 2x more l3 cache; more data can be stored in the l3 cache for quick access later
Much better PassMark score 9,544 vs 1,858 Around 5.2x better PassMark score
Much better overclocked clock speed (Air) 4.69 GHz vs 2.53 GHz More than 85% better overclocked clock speed (Air)
Much better PassMark (Single core) score 2,084 vs 1,046 Around 2x better PassMark (Single core) score
More threads 8 vs 2 6 more threads
Significantly better performance per watt 4.55 pt/W vs 0.9 pt/W More than 5x better performance per watt
Newer Apr, 2012 vs Jan, 2009 Release date over 3 years later
More cores 4 vs 2 Twice as many cores; run more applications at once
Better overclocked clock speed (Water) 4.8 GHz vs 4.32 GHz More than 10% better overclocked clock speed (Water)
