Rumors and reports about Apple’s iPhone 14 model have already begun to emerge. As you know, Apple and TSMC are working together for the chips of devices such as iPhone and iPad. Apple has to develop a new processor that will potentially be more powerful than the current A15 Bionic, and now the company is said to use 4nm manufacturing technology for the A16 Bionic SoC.
According to DigiTimes’ new dated report, the iPhone 14 series will be based on the 4nm process. For comparison, the A15 Bionic chip in the newly released iPhone 13 series uses the 5nm manufacturing technique. Apple started using the 5nm process with the A14 Bionic chip in the iPhone 12 series and iPad Air. The A15 Bionic still comes with the same production, but as you can imagine, some improvements have been made for better performance.
Recently, it was stated that TSMC had problems with its 3nm production technology. This may be the main reason why Apple and TSMC chose the 4nm process in the A16 Bionic SoCs to be used for the iPhone 14.
Earlier reports had also suggested that Apple had fully booked TSMC’s facilities for the production of 3nm chips. If the 4nm process is used next year, we can see iPhone models based on 3nm production technology in 2023. Again, it’s almost a year for the iPhone 14 and things may change in the future.
