Inside Apple’s A13 Bionic system-on-chip

Since the very first Apple-designed smartphone chip (the A4 back in 2010), the company has been a force to be reckoned with in mobile silicon design. It was with the A6 a couple years later, when Apple used its own CPU design instead of a licensed architecture, that its performance leadership really started to kick into high gear.

For the last several years, Apple’s CPU has really been untouchable. The A11 Bionic featured not only a custom Apple-designed CPU, but finally ditched the PowerVR-based graphics processor for its own custom GPU. In addition, it introduced the Neural Engine, a custom block of silicon separate from the CPU and GPU, focused on accelerating Machine Learning computations.
