Reasons to consider the
Intel x5-Z8350

Report a correction
Much newer manufacturing process 14 nm vs 65 nm A newer manufacturing process allows for a more powerful, yet cooler running processor
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
Higher clock speed 1.44 GHz vs 1.06 GHz More than 35% higher clock speed
More cores 4 vs 2 Twice as many cores; run more applications at once
Better overclocked clock speed (Air) 1.71 GHz vs 1.07 GHz More than 60% better overclocked clock speed (Air)
More threads 4 vs 2 Twice as many threads
Better overclocked clock speed (Water) 1.44 GHz vs 1.07 GHz More than 35% better overclocked clock speed (Water)
