According to rumors, Apple's "A19" and "M5" processors have been discovered in official Apple code.
This information, discovered by Twitter “@_orangera1n,” suggests the existence of a large amount of unreleased Apple processors. Following the trends of Apple’s processor identifiers, the most recent discoveries are believed to correspond to the processors , suggesting that work on these processors is ongoing.
Apple's Tatsu Signing Server (TSS) verifies firmware files by issuing unique certificates, called APTickets, that contain specific details, without any third-party logging. In order to detect unreleased ApChipIDs, TSS requests were made for each possible identifier. Those that did not return an invalid identifier appear to indicate an unreleased chip.

Among the discovered ApChipIDs, the ID number 0x8150 is believed to correspond to the A19, while the numbers 0x6050, 0x6051, and 0x6052 are believed to represent the M5 Pro, M5 Max, and M5 Ultra, respectively. This conclusion is made based on the logical sequence and patterns of previously released processors.
Assuming Apple continues to release new iPhone every year, the A19 processor could make its appearance in the 2025 iPhone Pro models. At present, it is believed that Apple's first 3nm processor, the A17 Bionic, is just a few weeks away from being announced in the iPhone 15 Pro models, offering a significant increase in performance and efficiency compared to all of Apple's processors based on TSMC and released in recent years.
