Report a correction
Much newer manufacturing process 22 nm vs 90 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
Much higher clock speed 3.5 GHz vs 1.3 GHz Around 2.8x higher clock speed
More advanced architecture x86-64 vs x86 A 64-bit architecture allows more RAM to be installed and accessed by the processor
Has a built-in GPU Yes vs No Somewhat common; A separate graphics adapter is not required
Much better overclocked clock speed (Air) 4.69 GHz vs 1.3 GHz More than 3.5x better overclocked clock speed (Air)
Has virtualization support Yes vs No Somewhat common; Boosts performance of virtual machines
More threads 8 vs 1 7 more threads
More cores 4 vs 1 3 more cores; run more applications at once
Much better overclocked clock speed (Water) 4.8 GHz vs 1.3 GHz Around 3.8x better overclocked clock speed (Water)
