Reasons to consider the
Intel Core i5 760

Report a correction
Much higher clock speed 2.8 GHz vs 1.2 GHz More than 2.2x higher clock speed
Significantly higher turbo clock speed 3.33 GHz vs 2 GHz More than 65% higher turbo clock speed
Much better overclocked clock speed (Air) 4.13 GHz vs 1.2 GHz Around 3.5x better overclocked clock speed (Air)
More l3 cache 8 MB vs 3 MB Around 2.8x more l3 cache; more data can be stored in the l3 cache for quick access later
More cores 4 vs 2 Twice as many cores; run more applications at once
Much better overclocked clock speed (Water) 4.49 GHz vs 1.2 GHz Around 3.8x better overclocked clock speed (Water)
More l3 cache per core 2 MB/core vs 1.5 MB/core Around 35% more l3 cache per core
