The Apple iPhone XS and iPhone XS Max are both powered by the A12 Bionic SoC, manufactured using TSMC's 7nm process. The Apple iPhone XR will also have the same chipset under the hood when that model launches on October 26th. The 2018 iPhones will be the only smartphones available this year in large quantities that are powered by a 7nm SoC inside. Last year's A11 Bionic chipset was built using the 10nm process.

The A11 Bionic carries a transistor density of 49 million transistors/square mm. With the smaller transistors on the A12 Bionic, the density works out ...
