Apple’s Unreleased Silicon Chips: A Peek Into the Future

Are you ready for a glimpse into Apple’s future? Well, thanks to some keen-eyed developers and a Twitter user known as @_orangera1n, we now have some exciting insights into what may lie ahead for Apple’s silicon chips. Hidden within Apple’s official code are tantalizing references to upcoming chips with the codenames “A19” and “M5.” This discovery has sparked a wave of speculation and anticipation among tech enthusiasts.

Unveiling the Apple Chip Identifiers

Every Apple chip comes with a unique identifier. Through careful analysis and deduction, it has been possible to decipher some potential chip identifiers. The codes discovered by @_orangera1n – 0x8130, 0x6050, 0x6051, and 0x6052 – are believed to correspond to the mysterious A19, M5 Pro, M5 Max, and M5 Ultra chips, respectively. While this deduction is not confirmed, it aligns with the logical sequence and patterns seen in previously released Apple chips.

Behind the Scenes: Tatsu Signing Server

To understand how these chip identifiers were unearthed, we must delve into the world of the Tatsu Signing Server (TSS). This vital component of Apple’s firmware verification process issues unique certificates called APTickets, containing specific details. What makes the TSS significant is its lack of third-party logs, ensuring the security and confidentiality of Apple’s unreleased products.

A clever strategy emerged in the quest to identify unreleased ApChipIDs. Requests were made for every possible identifier, and those that did not return an invalid identifier were potential candidates for an unreleased chip. This methodology led to the discovery of the intriguing A19 and M5 series chip identifiers.

The A19: A Chip of the Future

If the deductions are accurate, the A19 chip could debut in the much-anticipated iPhone 17 Pro models, expected to hit the market in 2025. As Apple continues its tradition of releasing new iPhone models annually, these future offerings are bound to be powered by advanced processing technology, unleashing unparalleled performance and efficiency.

A Sneak Peek into the M5 Series

While the A19 steals the limelight, the M5 series chips deserve their moment in the spotlight too. If our deductions are correct, we can look forward to the M5 Pro, M5 Max, and M5 Ultra chips joining Apple’s lineup in the not-too-distant future. These chips are expected to push the boundaries of what’s possible, delivering exceptional speed, power, and features to Apple devices.

The Road to the A17 Bionic

But before we get too carried away with visions of the A19 and the M5 series, let’s not forget about Apple’s imminent release: the A17 Bionic. This chip, built on the cutting-edge 3nm process, is poised to redefine performance benchmarks in the upcoming iPhone 15 Pro models. With significant advancements in both speed and efficiency, the A17 Bionic will undoubtedly dazzle users and set the stage for Apple’s future innovations.


The discovery of references to the A19 and M5 series chips in Apple’s official code has sent shockwaves through the tech community. While we await official confirmation from Apple, these tantalizing hints have ignited our imaginations and given us a glimpse of what could lie ahead in the world of Apple silicon chips. From the potential power of the A19 to the promise of the M5 series, it’s clear that Apple continues to push the boundaries of technological innovation. So, fasten your seatbelts and get ready for an exciting journey into the future of Apple’s chip designs.
