The iPhone X is getting a major boost in horsepower over past iPhone models thanks to a next-generation processor, the A11 Bionic. The processor features six cores compared with the previous four-core A10 Fusion. Two of the cores are for high performance, offering 25 percent faster processing than the A10. The other cores are for maximizing power efficiency of certain tasks, and are 70 percent faster, Apple said. In addition, the A11 Bionic integrates the first Apple-designed GPU, which offers 30 percent faster graphics over the A10. The new processor should go a long way toward supporting better productivity on the iPhone X. "Speed is the key. The new chip should improve application performance," Goldstein said.
