Much more l2 cache 6 MB vs 1 MB 6x more l2 cache; more data can be stored in the l2 cache for quick access later
Much newer manufacturing process 32 nm vs 130 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Significantly higher clock speed 3.5 GHz vs 2.4 GHz More than 45% higher clock speed
More cores 6 vs 1 5 more cores; run more applications at once
Much better overclocked clock speed (Air) 4.75 GHz vs 2.73 GHz Around 75% better overclocked clock speed (Air)
Newer Oct, 2012 vs May, 2004 Release date over 8 years later
More threads 6 vs 1 5 more threads
Much better overclocked clock speed (Water) 4.82 GHz vs 2.4 GHz More than 2x better overclocked clock speed (Water)
