Surprising no one, it turns out that the next generation iPhone will put an even bigger performance gap between itself and the rest of the industry, as TSMC begins mass production of powerful 7-nanometer A12 chips for use in Apple’s next-generation iPhones.
Smaller is better
TSMC announced volume production of 7-nanometer chips in April 2018 but did not say who it was producing these processors for. Bloomberg claims those chips are Apple’s.
Why does this matter?
It’s like this — a nanometer is one billionth of a meter. In chip design it represents the distance between the transistors that comprise the processor.
