Report a correction
Much more l2 cache 6 MB vs 1 MB 6x more l2 cache; more data can be stored in the l2 cache for quick access later
Much newer manufacturing process 45 nm vs 130 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Higher clock speed 2.66 GHz vs 2 GHz Around 35% higher clock speed
Much more l2 cache per core 3 MB/core vs 1 MB/core 3x more l2 cache per core
Significantly better overclocked clock speed (Air) 4 GHz vs 2.86 GHz Around 40% better overclocked clock speed (Air)
Newer Jan, 2008 vs May, 2004 Release date over 3 years later
More cores 2 vs 1 Twice as many cores; run more applications at once
Much better overclocked clock speed (Water) 4.08 GHz vs 2 GHz More than 2x better overclocked clock speed (Water)
Better PassMark score 1,885 vs 532 More than 3.5x better PassMark score
Higher Maximum operating temperature 72.4 °C vs 65 °C More than 10% higher Maximum operating temperature
Better performance per watt 1.64 pt/W vs 0.68 pt/W Around 2.5x better performance per watt
