As of iPhone 11, Apple’s own Bionic chip is built using 7-nanometers technology and 5-nanometers is expected in the next model. What’s next? Luke Dormehl:
The A-series chip in Apple’s 2020 iPhone is likely to take advantage of the 5-nanometer technology developed by chip designer TSMC. However, the chip giant is already hard at work on a 3-nanometer process it thinks will be ready in 2022.
Is thinner always better?
Achieving smaller numbers of nanometers between transistors is no guarantee of performance boosts. However, it does mean being able to pack more on which can greatly improve performance. 3-nanometer chips would be a massive achievement for TSMC at a time when some people worry that Moore’s Law may be coming to an end. Moore’s law states that the number of transistors on a circuit board roughly doubles every 12-18 months thanks to advances in miniaturization.
