While the upcoming Apple Watch Series 11, Apple Watch Ultra 3, and Apple Watch SE 3 will be powered by an updated S11 system in package (SiP), we may not see much in the way of processor performance improvements.
As first reported by MacRumors, accidentally leaked code shows the new SiP will have the same T8310 architecture as the S9 and S10 chips in the Series 9 and Series 10 Apple Watch models.
Apple has in the past used the same SiP architecture across multiple generations of its Apple Watch S-series chips. The S6, S7, and S8 chips all had the same core technology.
The S9 and S10 chips use two “Sawtooth” performance cores like the A16 Bionic chip, it’s a 64-bit dual-core processor with a 4-core Neural Engine, offering second-generation Ultra Wideband (UWB) support, and 64GB storage space.
While Apple may keep the underlying technology in place, it could tweak the process in other ways. Apple’s S10 chip had a thinner profile to take up less space in the Watch.
It’s likely Apple’s upcoming S12 chip for 2026 will use a new microarchitecture with performance improvements.
Apple is expected to unveil the Apple Watch Ultra 3, Apple Watch Series 11, and Apple Watch SE 3 models during Apple’s upcoming September event.
