Report a correction
Much more l2 cache 6 MB vs 2 MB 3x more l2 cache; more data can be stored in the l2 cache for quick access later
Much newer manufacturing process 45 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 3 GHz vs 1.5 GHz 2x higher clock speed
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Much more l2 cache per core 3 MB/core vs 2 MB/core 50% more l2 cache per core
Much better overclocked clock speed (Air) 4.22 GHz vs 2.17 GHz Around 95% better overclocked clock speed (Air)
Much better overclocked clock speed (Water) 4.23 GHz vs 1.5 GHz More than 2.8x better overclocked clock speed (Water)
More cores 2 vs 1 Twice as many cores; run more applications at once
