Reasons to consider the
Intel Core i3 2120

Report a correction
Much newer manufacturing process 32 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 3.3 GHz vs 1.7 GHz Around 95% higher clock speed
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Significantly better overclocked clock speed (Air) 3.42 GHz vs 2.53 GHz More than 35% better overclocked clock speed (Air)
More threads 4 vs 1 3 more threads
More cores 2 vs 1 Twice as many cores; run more applications at once
Much better overclocked clock speed (Water) 3.37 GHz vs 1.7 GHz Around 2x better overclocked clock speed (Water)
