Report a correction
Much more l2 cache 4 MB vs 0.25 MB 16x more l2 cache; more data can be stored in the l2 cache for quick access later
Much newer manufacturing process 32 nm vs 130 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 3.8 GHz vs 1.58 GHz Around 2.5x higher clock speed
More cores 4 vs 1 3 more cores; run more applications at once
More threads 4 vs 1 3 more threads
Much better overclocked clock speed (Air) 4.48 GHz vs 2.04 GHz Around 2.2x better overclocked clock speed (Air)
Much better PassMark score 4,651 vs 464 More than 10x better PassMark score
Much better PassMark (Single core) score 1,406 vs 622 More than 2.2x better PassMark (Single core) score
Much more l2 cache per core 1 MB/core vs 0.25 MB/core 4x more l2 cache per core
Has a NX bit Yes vs No Somewhat common; Prevents a common class of security exploits
Much better overclocked clock speed (Water) 4.98 GHz vs 1.58 GHz Around 3.2x better overclocked clock speed (Water)
Newer Oct, 2012 vs Jul, 2004 Release date over 8 years later
