Apple has 7 different in-house chips teased in iOS 18 code: A19, A19 Pro, C2 5G modem, and more

Apple is working on next-gen silicon that recently turned up in an internal build of iOS 18, including the new A19, A19 Pro, M5, and C2.

In a new report from AppleInsider, which had exclusive information provided to them, an internal build of iOS 18 included references to multiple unannounced Apple Silicon chips for a bunch of different hardware platforms. Apple's new iOS 18 has a build number of 22A91871y, is a NonUI variant of iOS 18, lacking the regular consumer-oriented iOS user interface, instead featuring just rudimentary applications designed primarily for hardware testing.

AppleInsider's report includes a video that explains how the unit's operating system contains codenames and identifiers that line up with multiple unreleased Apple Silicon chips, including new M-series processors, the next-generation C2 5G modem, an Apple Watch chip, and more.

The new NonUI build of iOS 18 references the following hardware codenames and CPIDs:

• Tilos - which likely corresponds to the base A19 chip
• Thera - A19 Pro (CPID: T8150)
• Hidra - possibly the standard M5 chip (CPID: T8142)
• Sotra - M5 Pro (CPID: T6050)
• Bora - A next-gen Apple Watch chip, based on the A18 (CPID: T8320)
• Proxima - An Apple Bluetooth-WiFi combo chip
• C4020 - Apple's C2 modem

We should expect more news on Apple's unreleased chips in the coming months, with its new M5 and A19 family of processors launching in the coming months, as well as its second-gen C2 5G modem that we've been reporting on in previous rumors. Apple's new M5-powered MacBook Pro laptops will launch in the coming months, with new iPhones launching in September that should see some variants rolling out with the new C2 5G modem inside.
