Unsurprisingly, TSMC TSMC will continue to be responsible for apple A14 chip contracts this year. TSMC has been the sole foundry for Apple’s A-Series chips for several years. This year, the A14 chip will use TSMC’s latest 5nm production process, with both the A12 and A13 making the 7nm process.
By the time the A12 appeared in the iPhone XS, 7nm was already the most advanced process of its time, and Apple was the world’s first smartphone manufacturer to use a 7nm process chip. Now that TSMC’s 5nm process is ripe, the iPhone is likely to become the world’s first smartphone with a 5nm process chip by 2020.
More advanced processes mean more transistors, better energy efficiency and better performance.
