Significantly higher clock speed 3.4 GHz vs 2.27 GHz Around 50% higher clock speed
Much newer manufacturing process 22 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Slightly more l3 cache 6 MB vs 4 MB 50% more l3 cache; more data can be stored in the l3 cache for quick access later
More cores 4 vs 2 Twice as many cores; run more applications at once
Newer Jun, 2012 vs Feb, 2010 Release date over 2 years later
More threads 4 vs 2 Twice as many threads
