Reasons to consider the
Intel Core i3 3120M

Report a correction
Is hyperthreaded Yes vs No Somewhat common; Maximizes usage of each CPU core
Significantly 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
Newer manufacturing process 22 nms vs 32 nms A newer manufacturing process allows for a more powerful, yet cooler running processor
More threads 4 vs 2 Twice as many threads
Much more l3 cache per core 1.5 MB/core vs 0.25 MB/core 6x more l3 cache per core
Significantly better PassMark (Overclocked) score 1,976.5 vs 982.4 More than 2x better PassMark (Overclocked) score
Better PassMark score 3,342 vs 1,631 More than 2x better PassMark score
Better 3DMark06 CPU score 3,057 vs 1,804 Around 70% better 3DMark06 CPU score
Better PassMark (Single core) score 1,313 vs 995 More than 30% better PassMark (Single core) score
Better geekbench (64-bit) score 4,539 vs 3,018 More than 50% better geekbench (64-bit) score
Better 3DMark11 physics score 3,120 vs 2,370 More than 30% better 3DMark11 physics score
Slightly better performance per watt 12.53 pt/W vs 8.05 pt/W More than 55% better performance per watt
Marginally newer Sep, 2012 vs May, 2012 Release date 4 months later
