About a week ago, it was reported that the A19 chip of the 2019 iPhone configuration will continue to be built using the same 7-nanometer process as the A12.
Today, Taiwanese media Digitimes reported that for the 2020 version of the iPhone, we will once again see a new leap in the production process of Apple chips.
Digitimes said that TSMC is expected to receive Apple's first 5 nanometer chip orders next year.
Manufacturing size is not directly related to performance, but the small gap between transistors usually means higher power efficiency and more transistors in the same surface area, which helps improve performance.
Apple made a big move last year to build A12 chips in a 7-nanometer process. It was the first company (and even a few now) to launch a 7-nm processor.
The iPhone's A12 and iPad's A12X chips far surpass their competitors in terms of computing benchmarks. Even last year's iPhone, at least in terms of comprehensive benchmark scores, can still compete with modern Android flagship smartphones.
A13 will continue to use the 7nm process. However, TSMC will use EUV technology for the first time. EUV can arrange more complex tiny patterns on the chip. TSMC will apply EUV technology for the first time on four key layers.
Later this year, it plans to apply EUV technology on up to 14 layers. Given the upgrade plan for the Apple supply chain, the A13 is expected to be produced using a more conservative process.
