Inside the iPhone 8 Plus, there's a new six-core A11 Bionic chip, which Apple says is the smartest, most powerful chip ever introduced in a smartphone. There are two performance cores that are 25 percent faster than the A10 Fusion chip in the iPhone 7, and four efficiency cores that are 70 percent faster.
With a new second-generation performance controller, all six cores can be harnessed at the same time for much improved speeds when handling multi-threaded workloads. There's a new Apple-designed 3-core GPU that's 30 percent faster than the previous-generation GPU, and two of the cores, the Neural Engine, make machine learning tasks faster than ever.
