Reasons to consider the
Intel Core i3 2120

Report a correction
Much higher clock speed 3.3 GHz vs 1.7 GHz Around 95% higher clock speed
Is hyperthreaded Yes vs No Somewhat common; Maximizes usage of each CPU core
Much better turbo clock speed 1,100 MHz vs 680 MHz More than 60% better turbo clock speed
Significantly higher GPU clock speed 850 MHz vs 523 MHz Around 65% higher GPU clock speed
Much better PassMark (Single core) score 1,679 vs 451 Around 3.8x better PassMark (Single core) score
Significantly better overclocked clock speed (Air) 3.44 GHz vs 1.72 GHz Around 2x better overclocked clock speed (Air)
Significantly more l3 cache per core 1.5 MB/core vs 0.25 MB/core 6x more l3 cache per core
Slightly more l3 cache 3 MB vs 0.5 MB 6x more l3 cache; more data can be stored in the l3 cache for quick access later
