Much more l3 cache 24 MB vs 12 MB 2x more l3 cache; more data can be stored in the l3 cache for quick access later
Significantly higher clock speed 2.13 GHz vs 1.87 GHz Around 15% higher clock speed
Higher turbo clock speed 2.4 GHz vs 2.13 GHz Around 15% higher turbo clock speed
More threads 16 vs 12 4 more threads
Newer manufacturing process 32 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l3 cache per core 3 MB/core vs 2 MB/core 50% more l3 cache per core
Much better overclocked clock speed (Air) 2.36 GHz vs 2 GHz Around 20% 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 Apr, 2011 vs Mar, 2010 Release date a year later
