Reasons to consider the
Intel Core i3 3120M

Report a correction
Is hyperthreaded Yes vs No Somewhat common; Maximizes usage of each CPU core
Much newer manufacturing process 22 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
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
Much better turbo clock speed 1,100 MHz vs 655 MHz Around 70% better turbo clock speed
Much more l3 cache per core 1.5 MB/core vs 0.25 MB/core 6x more l3 cache per core
Higher GPU clock speed 650 MHz vs 480 MHz More than 35% higher GPU clock speed
More threads 4 vs 2 Twice as many threads
Better 3DMark06 CPU score 3,057 vs 1,684 More than 80% better 3DMark06 CPU score
Better PassMark score 3,342 vs 1,699 More than 95% better PassMark score
Better PassMark (Single core) score 1,313 vs 1,054 Around 25% better PassMark (Single core) score
Better geekbench (64-bit) score 4,083 vs 2,583 Around 60% better geekbench (64-bit) score
Slightly better performance per watt 12.48 pt/W vs 6.72 pt/W More than 85% better performance per watt
Newer Sep, 2012 vs May, 2012 Release date 4 months later
