According to the news from Twitter broke the news, Mr-white @laobaiTD, he posted a component diagram of the A14 chip. The name and number of the A14 are clearly visible in the picture. In addition, he also posted pictures of A14 RAM components. Of course, we cannot confirm the authenticity for the time being, and the previous revelations of Mr-white are also accurate.
TSMC's 5nm chip has been mass-produced. The main customer of the factory's 5nm chip is Apple's foundry A14 processor, so it can be expected that the performance of A14 will be much stronger than that of A13.
