#Apple A Series Processor

If you know anything about iPhone internals, you might know that under the hood, your iPhone has Apple's A-xx processor. It ran on Apple's first in-house designed processor, the A4. Now, every year, a new A-series chipset from Apple is released and pitted against the latest Qualcomm Snapdragon, HiSilicon Kirin, and Samsung Exynos chipsets in AnTuTu and Geekbench. The fact is Apple designs processors that use ARM's 64-bit architecture. What makes Apple's A-series chipsets unique is that they hold an architectural license with ARM, which allows it to design its own chips from scratch. Apple's first in-house 64-bit ARM processor was the Apple A7 found in the iPhone 5S. And by September of 2014, Apple debuted its A9 processor found in the iPhone 6S. By the time of the publishing of this article, Apple's latest chip is the A13 Bionic on the iPhone 11 series, which on paper, performs 30% more power-efficient than the A12 chip -- which lives inside the iPhone Xs' and the iPhone XR.
