Much higher clock speed 2.4 GHz vs 2 GHz Around 20% higher clock speed
Much higher turbo clock speed 3.2 GHz vs 2.4 GHz Around 35% higher turbo clock speed
More l3 cache 20 MB vs 18 MB More than 10% more l3 cache; more data can be stored in the l3 cache for quick access later
Much lower typical power consumption 69.06W vs 105.63W Around 35% lower typical power consumption
Newer manufacturing process 22 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better overclocked clock speed (Air) 2.75 GHz vs 2.4 GHz Around 15% better overclocked clock speed (Air)
More l3 cache per core 2.5 MB/core vs 2.25 MB/core More than 10% more l3 cache per core
Newer Jul, 2014 vs Mar, 2010 Release date over 4 years later
Much lower annual commercial energy cost 74.46 $/year vs 113.88 $/year Around 35% lower annual commercial energy cost
Much lower annual home energy cost 20.48 $/year vs 31.32 $/year Around 35% lower annual home energy cost
