The chip inside the iPhone X and iPhone 8 makes them more powerful than a 2017 MacBook Pro (AAPL)

Apple’s A11 Bionic is among them: It one-upped its predecessor, 2016’s A10 Fusion, by adding two extra cores, as well as throwing in the first Apple-designed graphics processing unit and even a dedicated neural engine, which mainly takes care of Face ID on the iPhone X.
