Much newer manufacturing process 32 nm vs 180 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
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
Higher clock speed 2.4 GHz vs 1.73 GHz Around 40% 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 1 MB/core vs 0.25 MB/core 4x more l2 cache per core
More cores 4 vs 1 3 more cores; run more applications at once
Significantly better overclocked clock speed (Air) 3.2 GHz vs 2.13 GHz More than 50% better overclocked clock speed (Air)
Better PassMark score 3,064 vs 323 Around 9.5x better PassMark score
Better PassMark (Single core) score 860 vs 503 More than 70% better PassMark (Single core) score
More threads 4 vs 1 3 more threads
Better performance per watt 2.2 pt/W vs 0.62 pt/W More than 3.5x better performance per watt
Significantly better overclocked clock speed (Water) 2.8 GHz vs 1.73 GHz More than 60% better overclocked clock speed (Water)
