Report a correction
Much newer manufacturing process 22 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Higher clock speed 2.9 GHz vs 2.3 GHz More than 25% higher clock speed
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
More l2 cache 1 MB vs 0.5 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Significantly better PassMark (Single core) score 1,560 vs 765 More than 2x better PassMark (Single core) score
Significantly more l2 cache per core 0.5 MB/core vs 0.13 MB/core 4x more l2 cache per core
Better overclocked clock speed (Air) 3.03 GHz vs 2.3 GHz More than 30% better overclocked clock speed (Air)
Newer Jan, 2013 vs May, 2010 Release date over 2 years later
Better overclocked clock speed (Water) 3.1 GHz vs 2.3 GHz Around 35% better overclocked clock speed (Water)
