Intel Core i5 3320M

Report a correction
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
Slightly higher turbo clock speed 3.3 GHz vs 3.2 GHz Around 5% higher turbo clock speed
Much better performance per dollar 2.94 pt/$ vs 0.48 pt/$ More than 6x better performance per dollar
Supports trusted computing Yes vs No Somewhat common; Allows for safer, more reliable computing
More l2 cache per core 0.5 MB/core vs 0.25 MB/core 2x more l2 cache per core
Better turbo clock speed 1,200 MHz vs 1,100 MHz Around 10% better turbo clock speed
Slightly better sky diver score 1,946 vs 1,796 Around 10% better sky diver score
