Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Is hyperthreaded Yes vs No Somewhat common; Maximizes usage of each CPU core
Newer manufacturing process 32 nms vs 45 nms A newer manufacturing process allows for a more powerful, yet cooler running processor
Higher clock speed 3.3 GHz vs 2.93 GHz Around 15% higher clock speed
Significantly better PassMark (Single core) score 1,682 vs 1,204 Around 40% better PassMark (Single core) score
More threads 4 vs 2 Twice as many threads
Better PassMark score 3,874 vs 1,881 More than 2x better PassMark score
Better 3DMark11 physics score 3,880 vs 2,250 More than 70% better 3DMark11 physics score
Better geekbench (64-bit) score 5,483 vs 2,956 More than 85% better geekbench (64-bit) score
Marginally newer Jan, 2011 vs Jan, 2009 Release date over 2 years later
Better performance per watt 8.94 pt/W vs 5.85 pt/W Around 55% better performance per watt
