Report a correction
Much newer manufacturing process 45 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much more l2 cache 3 MB vs 1 MB 3x more l2 cache; more data can be stored in the l2 cache for quick access later
Higher clock speed 2.93 GHz vs 2.6 GHz Around 15% higher clock speed
Much lower typical power consumption 52.81W vs 84.5W Around 40% lower typical power consumption
Much more l2 cache per core 1.5 MB/core vs 1 MB/core 50% more l2 cache per core
Better PassMark (Single core) score 1,204 vs 749 More than 60% better PassMark (Single core) score
Significantly better overclocked clock speed (Air) 3.85 GHz vs 3.02 GHz Around 30% better overclocked clock speed (Air)
Newer Jan, 2009 vs Apr, 2005 Release date over 3 years later
Higher Maximum operating temperature 74.1 °C vs 65 °C Around 15% higher Maximum operating temperature
More cores 2 vs 1 Twice as many cores; run more applications at once
Better performance per watt 1.9 pt/W vs 0.53 pt/W More than 3.5x better performance per watt
Better PassMark score 1,877 vs 658 More than 2.8x better PassMark score
Much better overclocked clock speed (Water) 4.06 GHz vs 2.6 GHz More than 55% better overclocked clock speed (Water)
Much lower annual home energy cost 15.66 $/year vs 25.05 $/year Around 40% lower annual home energy cost
Much lower annual commercial energy cost 56.94 $/year vs 91.1 $/year Around 40% lower annual commercial energy cost
