Leaked S11 Chip Details Reveal No Major Performance Upgrades for 2025 Apple Watches – MacRumors

🔍 Summary:

Apple is set to release its new Apple Watch models—the Series 11, Ultra 3, and SE 3—at an upcoming September event. These models will feature the updated S11 system in package (SiP), which, despite being based on the same T8310 architecture used in the previous S9 and S10 chips, may not offer significant improvements in processor performance. This architecture, also found in the A16 Bionic chip, includes two “Sawtooth” performance cores and supports a 64-bit dual-core processor, a 4-core Neural Engine, second-generation Ultra Wideband (UWB), and 64GB storage space.

While the core technology remains unchanged, Apple has historically made other modifications, such as the thinner chip redesign seen in the S10, to enhance the overall device design and functionality. Looking ahead, Apple is likely to introduce a new microarchitecture with the S12 chip in 2026, which is expected to bring notable performance enhancements.
