Conflict mystery: A16 chip claims 4nm, but is actually labeled 5nm

The news on August 22 attracted widespread attention. This news involved iPhone 14 Pro and iPhone 14 Pro Max. According to reports, the two phones are expected to be equipped with the A16 Bionic chip, but the internal markings have caused some controversy. Sources who broke the news revealed that the A16 chip is labeled as a 5-nanometer chip within Apple, rather than the 4-nanometer process generally believed by the outside world. This difference may explain why the M2 Pro and M2 Max chips used by Apple in the newly released 14-inch and 16-inch MacBook Pro models are said in the press release to be manufactured on the 5nm process, rather than the 4nm process

According to our understanding, someone broke the news on UReddit that Apple internally classifies the A16 bionic chip as a 5-nanometer chip. Although it is widely expected to use a 4nm process, the difference in internal markings may mean that Apple has made adjustments in process technology, or there are some special technical details. This may also be the reason why at the press conference, the M2 Pro and M2 Max chips were emphasized to be based on the 5nm process. This may be a hint from Apple to new technologies

At the same time, news about the A17 bionic chip continues to emerge. The A17 chip is expected to be manufactured using TSMC's most advanced 3nm process, which will bring huge potential for performance improvements. It is understood that the performance leap between A16 and A17 will be significant when switching from 5nm process to 3nm process. According to some previous benchmark test results, the single-core and multi-core performance of the A17 Bionic chip has improved by up to 31% compared to the previous generation.

The latest revelations add to the upcoming iPhone 15 Pro and iPhone 15 Pro Max More appeal. It is expected that these two mobile phones will be equipped with A17 bionic chip, bringing more powerful performance and experience to users. The more affordable iPhone 15 and iPhone 15 Plus may continue to use the A16 bionic chip to balance the relationship between performance and cost. Discussions about chip manufacturing processes are becoming increasingly heated. Some claim that the Snapdragon 8 Gen 2 chip is also manufactured using a similar "5nm" process, but may have better power efficiency than the A16 Bionic chip in some aspects. Of course, whether TSMC’s 3nm process is truly a technological breakthrough, and whether N3E technology has truly achieved a substantial 3nm process, still requires further verification and explanation
