The new iPhone 8 camera packs a new chip called the A11 bionic, which is loaded with an upgraded amount of power with a 6-core chip — but that’s probably not the most important part of the company’s announcement.

Apple is including a custom-designed GPU in the iPhone 8. GPUs excel at machine learning thanks to their ability to spread out the kinds of rapid calculations across an array of cores that are required for machine learning, like natural language processing and image recognition. They’re great for games, sure, but this is a big step for Apple as it looks to lock people into its ecosystem with Siri across an array of devices.
