Reasons to consider the
Intel Core i5 3330S

Report a correction
Much more l2 cache 1 MB vs 0.5 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
More cores 4 vs 2 Twice as many cores; run more applications at once
Much newer manufacturing process 22 nm vs 32 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
More number of displays supported 3 vs 2 1 more number of displays supported
Newer Sep, 2012 vs Jan, 2011 Release date over 1 years later
