Report a correction
Significantly higher turbo clock speed 3 GHz vs 2.4 GHz More than 25% higher turbo clock speed
Higher clock speed 2.3 GHz vs 2.13 GHz Around 10% higher clock speed
More threads 20 vs 16 4 more threads
More l3 cache 25 MB vs 24 MB Around 5% more l3 cache; more data can be stored in the l3 cache for quick access later
Newer manufacturing process 22 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Better overclocked clock speed (Air) 2.44 GHz vs 2.36 GHz Around 5% better overclocked clock speed (Air)
Newer Jul, 2014 vs Apr, 2011 Release date over 3 years later
Better overclocked clock speed (Water) 2.3 GHz vs 2.13 GHz Around 10% better overclocked clock speed (Water)
