Intel Core i3 540

Report a correction
Much more l3 cache 4 MB vs 0.5 MB 8x more l3 cache; more data can be stored in the l3 cache for quick access later
Much newer manufacturing process 32 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 3.06 GHz vs 2.3 GHz Around 35% higher clock speed
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
More threads 4 vs 1 3 more threads
Much better PassMark score 2,694 vs 617 More than 4.2x better PassMark score
Much better PassMark (Single core) score 1,220 vs 644 Around 90% better PassMark (Single core) score
Much better overclocked clock speed (Air) 4.47 GHz vs 2.95 GHz More than 50% better overclocked clock speed (Air)
More cores 2 vs 1 Twice as many cores; run more applications at once
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Much better overclocked clock speed (Water) 3.07 GHz vs 2.3 GHz Around 35% better overclocked clock speed (Water)
