Report a correction
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 2.67 GHz More than 10% higher clock speed
Much more l2 cache per core 3 MB/core vs 2 MB/core 50% more l2 cache per core
Better overclocked clock speed (Air) 4.22 GHz vs 3.43 GHz Around 25% better overclocked clock speed (Air)
Better PassMark (Single core) score 1,251 vs 1,062 Around 20% better PassMark (Single core) score
Much better overclocked clock speed (Water) 4.23 GHz vs 2.67 GHz Around 60% better overclocked clock speed (Water)
