Significantly more l2 cache 2 MB vs 1 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Much newer manufacturing process 14 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better performance per dollar 4.22 pt/$ vs 2.12 pt/$ Around 2x better performance per dollar
Significantly better CompuBench 1.5 ocean surface simulation score 84.61 fps vs 27.65 fps More than 3x better CompuBench 1.5 ocean surface simulation score
More number of displays supported 3 vs 2 1 more number of displays supported
More cores 4 vs 2 Twice as many cores; run more applications at once
Newer Jan, 2015 vs Jun, 2011 Release date over 3 years later
