Is hyperthreaded Yes vs No Somewhat common; Maximizes usage of each CPU core
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much newer manufacturing process 22 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much better PassMark (Overclocked) score 6,731.8 vs 1,679.1 More than 4x better PassMark (Overclocked) score
Significantly better PassMark (Single core) score 2,088 vs 1,345 More than 55% better PassMark (Single core) score
Better PassMark score 9,614 vs 4,600 More than 2x better PassMark score
Newer Apr, 2012 vs Sep, 2008 Release date over 3 years later
Better performance per dollar 3.79 pt/$ vs 2.2 pt/$ More than 70% better performance per dollar
Higher Maximum Operating Temperature 67.4 °C vs 63 °C More than 5% higher Maximum Operating Temperature
Significantly better overclocked clock speed (Water) 4.6 GHz vs 3.33 GHz Around 40% better overclocked clock speed (Water)
