Report a correction
Much more l2 cache 12 MB vs 8 MB 50% more l2 cache; more data can be stored in the l2 cache for quick access later
Significantly higher clock speed 2.13 GHz vs 1.86 GHz Around 15% higher clock speed
Much more l2 cache per core 3 MB/core vs 2 MB/core 50% more l2 cache per core
Newer manufacturing process 45 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Significantly better overclocked clock speed (Air) 2.13 GHz vs 1.87 GHz Around 15% better overclocked clock speed (Air)
Significantly better overclocked clock speed (Water) 2.13 GHz vs 1.87 GHz Around 15% better overclocked clock speed (Water)
Newer Sep, 2008 vs Sep, 2007 Release date over a year later
