As you might have learned a long time ago, Apple designs its own Central Processing Units (CPU) for the iPhone and has them manufactured by TSMC using the 5nm process node. The A14 Bionic chips each contain 15 billion transistors packed together in a density of 171.3 million transistors per square mm. The higher the transistor density, the more powerful and energy-efficient a chip is. The 2020 iPhone models could be the first smartphones equipped with 5nm chipsets.
