References to what could be the “A19” and “M5” Apple silicon chips have been discovered in code in an Apple backend server.
The references were found by Twitter user “@_orangera1n,” which indicates the existence of a large number of unreleased Apple chips. The latest discoveries are believed to be the “A19,” “M5 Pro,” “M5 Max,” and “M5 Ultra” chips, indicating that work on these processors is currently underway.
Apple’s Tatsu Signing Server (TSS), verifies firmware files by issuing unique certificates called APTickets, which contain specific details, with no third-party logs. In an effort to identify unreleased ApChipIDs, TSS requests were made for every possible identifier. Any requests that did not return an invalid identifier seemingly indicate the existence of an unreleased chip.
The discovered ApChipIDs include the identifier 0x8150 which is believed to represent the A19, while 0x6050, 0x6051, and 0x6052 are believed to represent the M5 Pro, M5 Max, and M5 Ultra, respectively.
Apple’s first 3nm chip, the A17 Bionic is expected to make its debut in Apple’s upcoming iPhone 15 Pro models, which will likely debut in September. That means the A19 could debut in 2025’s iPhone 17 Pro models.
