Reasons to consider the
Intel Core i3 3120M

Report a correction
Is hyperthreaded Yes vs No Somewhat common; Maximizes usage of each CPU core
Higher clock speed 2.5 GHz vs 1.9 GHz More than 30% higher clock speed
Newer manufacturing process 22 nms vs 32 nms A newer manufacturing process allows for a more powerful, yet cooler running processor
Significantly better PassMark (Overclocked) score 1,976.5 vs 1,054.9 More than 85% better PassMark (Overclocked) score
Better PassMark (Single core) score 1,313 vs 848 Around 55% better PassMark (Single core) score
Better 3DMark11 physics score 3,120 vs 2,080 50% better 3DMark11 physics score
Better geekbench (64-bit) score 4,539 vs 2,862 Around 60% better geekbench (64-bit) score
Better 3DMark06 CPU score 3,057 vs 2,438 More than 25% better 3DMark06 CPU score
Better PassMark score 3,342 vs 2,679 Around 25% better PassMark score
Slightly better overclocked clock speed (Air) 2.54 GHz vs 2.33 GHz Around 10% better overclocked clock speed (Air)
Significantly better overclocked clock speed (Water) 2.5 GHz vs 1.9 GHz More than 30% better overclocked clock speed (Water)
Marginally newer Sep, 2012 vs May, 2012 Release date 4 months later

Much more l2 cache 4 MB vs 1 MB 4x more l2 cache; more data can be stored in the l2 cache for quick access later
Much better performance per dollar 12.06 pt/$ vs 2 pt/$ More than 6x better performance per dollar
More cores 4 vs 2 Twice as many cores; run more applications at once
Much more l2 cache per core 1 MB/core vs 0.5 MB/core 2x more l2 cache per core
Significantly higher Maximum Operating Temperature 100 °C vs 90 °C More than 10% higher Maximum Operating Temperature
