The iPhone 12 is powered by Apple's A14 Bionic chip, which is a six-core processor with two high-performance cores and four efficiency cores.

The iPhone 12 is powered by Apple's A14 Bionic chip, which is a six-core processor with two high-performance cores and four efficiency cores. This chip is the first to use a 5-nanometer process, which allows for more transistors to be packed into a smaller space, resulting in improved performance and energy efficiency. The high-performance cores in the A14 Bionic chip are designed to handle demanding tasks such as gaming and video editing. 

These cores are up to 50% faster than the A13 Bionic chip used in the iPhone 11, while also being more energy-efficient. This means that the iPhone 12 can handle tasks more quickly and smoothly while using less battery power. The efficiency cores in the A14 Bionic chip are designed to handle less demanding tasks such as browsing the web and checking email. These cores are up to 50% faster than the A13 Bionic chip while also using less power. This means that the iPhone 12 can handle basic tasks more quickly and efficiently, which helps to extend the battery life of the device. 

In addition to the high-performance and efficiency cores, the A14 Bionic chip also includes a four-core GPU (graphics processing unit). This GPU provides up to 50% faster graphics performance compared to the A13 Bionic chip, which is especially beneficial for gaming and other graphics-intensive tasks. The A14 Bionic chip also includes a next-generation Neural Engine, which is designed to handle machine learning tasks. This engine can perform up to 11 trillion operations per second, which is twice as fast as the A13 Bionic chip. This improved performance allows for features such as improved camera performance, more accurate facial recognition, and improved battery life. 

 Overall, the A14 Bionic chip is a significant improvement over the A13 Bionic chip used in the iPhone 11. Its six-core design, including two high-performance cores and four efficiency cores, provides improved performance and energy efficiency for demanding and less demanding tasks. The four-core GPU provides improved graphics performance, while the next-generation Neural Engine allows for improved machine learning capabilities. All of these improvements contribute to making the iPhone 12 a powerful and efficient smartphone that is capable of handling even the most demanding tasks.
