Discovery of new Apple Silicon chips: Clues to A19 and M5 in official Apple code [2023]

Summary

• Indicative signs about Apple's alleged "A19" and "M5" silicon chips were discovered in the official Apple code.
• The discoveries suggest that progress is being made on the "A19", "M5 Pro", "M5 Max", and "M5 Ultra" processors.
• The A19 chip is suspected to possibly debut in the ‌iPhone‌ 17 Pro models of 2025.

Discovery of New Apple Silicon Chips in Progress

Vigilant tech enthusiasts have identified references to the supposed "A19" and "M5" silicon chips from Apple in the official Apple code. This discovery, made by Twitter user "@_orangera1n", points to a variety of unreleased Apple chips. Based on the trends of Apple's chip-IDs, the latest discoveries are interpreted as hints towards the "A19", "M5 Pro", "M5 Max" and "M5 Ultra" chips, suggesting that work on these processors is ongoing.

Identifying the Chips

Apple's Tatsu Signing Server (TSS) verifies firmware files by issuing unique certificates known as APTickets, which include specific details without requiring third parties to generate logfiles. To identify unreleased ApChipIDs, TSS queries were made for each possible identifier. Those that did not return an invalid identifier appear to indicate an unreleased chip.

Conclusions and Speculation

Among the discovered ApChipIDs, the identifier 0x8130 is thought to correspond to the A19, while 0x6050, 0x6051, and 0x6052 likely represent the M5 Pro, M5 Max, and M5 Ultra chips. This conclusion is based on the logical sequence and patterns observed with previously released chips. Assuming Apple continues to release new iPhone models annually, the A19 chip could debut in the ‌iPhone‌ 17 Pro models in 2025. Presently, it's anticipated that Apple's first 3nm chip, the A17 Bionic, is just weeks away from being announced in the iPhone 15 Pro, showcasing significant performance and efficiency improvements over all current Apple silicon chips based on TSMC's 5nm process.

In a Nutshell

The purported Apple Silicon chips "A19" and "M5" have been recently discovered in Apple's code. These references are indicative of progress on a range of unreleased chips, including "A19", "M5 Pro", "M5 Max", and "M5 Ultra". Based on previous patterns and sequences, the A19 is expected to potentially debut in the ‌iPhone‌ 17 Pro models of 2025. Meanwhile, Apple's first 3nm chip, the A17 Bionic, is already expected for the iPhone 15 Pro models, promising notable performance and efficiency enhancements over current chips.
