What is new in A13 Bionic chip?

The A13 Bionic chip is the most high speed ever in a smartphone. The A13 Bionic chip is also the most power-efficient chip ever made by up to 40 percent. The increase helps supply up to four additional hours of battery charge for the iPhone 11 Pro and about five hours for the iPhone 11 Pro Max.

It contains hundreds of voltage gates and thousands of clock gates which may close off power to sections of the chip when it's not using them. The chip has the most machine learning performance, with an eight-core neural engine that adds "6x faster matrix multiplication." Overall, the chip is capable of one trillion operations per second.l
