During its September 10 iPhone 11 keynote, Apple marketed its A13 Bionic as the fastest and most efficient mobile chipset to power handsets. Looking at the performance gap between SoCs running in competing Android smartphones, we’d definitely agree with the California-based giant here. Now, in the latest interview with Apple’s Senior Vice President of Worldwide Marketing and hardware engineer Anand Shimpi, both individuals take a deeper dive into what makes the A13 Bionic so special.

In a feature by WIRED, Schiller told the publication that the biggest performance increases this year that customers can witness from the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max is text-to-speech. According to the Apple executive, this was all made possible thanks to machine learning and the neural engine running in the A13 Bionic.
