Apple has booked nearly 90% of chip supplier TSMC's first-generation 3-nanometer process capacity this year for future iPhones, Macs, and iPads, according to industry sources cited by DigiTimes , providing the Taiwanese foundry with significant growth momentum in the second half of 2023. Apple's upcoming iPhone 15 Pro models are expected to feature the A17 Bionic processor, Apple's first iPhone chip based on TSMC's first-generation 3nm process, also known as N3B. The 3nm technology is said to deliver a 35% power efficiency improvement and 15% faster performance compared to 4nm, which was used to make the A16 Bionic chip for the iPhone 14 Pro and Pro Max. Apple's M3 chip for Macs and iPads is also expected to use the 3nm process. The first M3 devices are expected to include an updated 13-inch MacBook Air and 24-inch iMac , both of which could arrive later this year. New iPad Pro models coming next year are likely to be powered by M3 chips
