The Power Within iPhone 12

All iPhones in the 12 series have a powerful new A14 Bionic processor, but what’s so special about it? Let’s get under the hood and check it out.

The 12-series iPhones are powered by a great new Apple-designed processor that’s streets ahead of its rivals. A14 Bionic is the first chip in the smartphone industry built on the five-nanometer process, making its transistors thinner and smaller than ever before. But why does this matter? According to Hope Giles, Apple’s Vice President of Engineering Program Management, Hardware Technologies, “The reduction in transistor size enables us to add features and increase performance, all while improving energy efficiency.”

Apple’s engineering team has certainly been hard at work on the design. The A14 Bionic chip contains an incredible 11.8 billion transistors, an increase of almost 40 percent over the previous generation of chips.

Its CPU (Central Processing Unit) has six cores, that is, six individual processors that can each work on specific tasks. Two are high-performance cores and four are designed for high efficiency. It’s the fastest CPU in any smartphone, performing up to 50 percent faster than its closest rival.

The GPU (Graphics Processing Unit) built into the A14 Bionic has four cores, driving increased image quality and overall efficiency. Gamers take note – your games have just got better! It’s the fastest GPU in any smartphone, and is up to 50 percent faster than other manufacturers’ comparable phones.

Pushing the limits of machine learning (ML), A14 Bionic features a 16-core Neural Engine for an 80 percent increase in performance. It’s capable of completing 11 trillion operations per second, enabling improved performance on even the most intense ML models. Machine learning harnesses the power of artificial intelligence to allow a system to automatically ‘learn’ from experience, and it’s the next big thing in computing. It’s certainly big in the 12-series iPhones.
