Much more l2 cache 6 MB vs 4 MB 50% more l2 cache; more data can be stored in the l2 cache for quick access later
Much newer manufacturing process 45 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Higher clock speed 3 GHz vs 2.4 GHz More than 25% higher clock speed
Much more l2 cache per core 3 MB/core vs 2 MB/core 50% more l2 cache per core
Supports trusted computing Yes vs No Somewhat common; Allows for safer, more reliable computing
Better PassMark (Single core) score 1,251 vs 853 More than 45% better PassMark (Single core) score
Better overclocked clock speed (Air) 4.22 GHz vs 3.46 GHz More than 20% better overclocked clock speed (Air)
Higher Maximum operating temperature 72.4 °C vs 60.1 °C More than 20% higher Maximum operating temperature
Much better overclocked clock speed (Water) 4.23 GHz vs 2.4 GHz More than 75% better overclocked clock speed (Water)
