Report a correction
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
Higher clock speed 2.2 GHz vs 1.6 GHz Around 40% higher clock speed
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much better performance per dollar 2.53 pt/$ vs 0.76 pt/$ More than 3.2x better performance per dollar
Much newer manufacturing process 32 nm vs 45 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
More l2 cache 1 MB vs 0.5 MB 2x more l2 cache; more data can be stored in the l2 cache for quick access later
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
Significantly better PassMark (Single core) score 1,136 vs 236 More than 4.8x better PassMark (Single core) score
Newer Sep, 2012 vs Jun, 2008 Release date over 4 years later
Better PassMark score 2,073 vs 271 Around 7.8x better PassMark score
Better overclocked clock speed (Air) 2.35 GHz vs 1.87 GHz More than 25% better overclocked clock speed (Air)
More cores 2 vs 1 Twice as many cores; run more applications at once
Better overclocked clock speed (Water) 2.2 GHz vs 1.6 GHz Around 40% better overclocked clock speed (Water)
