The iPhone 16 and iPhone 16 Plus will function 8GB of reminiscence and an A17 Bionic chip fabricated with TSMC’s N3E course of, in accordance with Jeff Pu, a tech analyst at Hong Kong funding agency Haitong Worldwide Securities.
In a word to traders seen by MacRumors, Pu famous the numerous RAM enhance for the usual iPhone fashions subsequent 12 months and the swap to LPD5 reminiscence. Apple’s commonplace iPhone fashions have had 6GB of reminiscence since 2021’s iPhone 13. The iPhone 15 and iPhone 15 Plus are anticipated to proceed the development. The iPhone 15 Professional and iPhone 15 Professional Max are anticipated to be the primary iPhones to function 8GB of reminiscence, which means that each the A17 Bionic and 8GB of reminiscence from this 12 months’s Professional fashions will trickle all the way down to the usual fashions a 12 months later.
Pu added that the A17 and A18 Bionic chips used within the iPhone 16 lineup might be fabricated with TMSC’s N3E course of, its enhanced 3nm node. The A17 Bionic used within the iPhone 15 Professional and iPhone 15 Professional Max is predicted to be Apple’s first chip manufactured with a 3nm fabrication course of, leading to main efficiency and effectivity enhancements over the 5nm method used for the A14, A15, and A16 chips.
The A17 Bionic chip used within the iPhone 15 Professional and iPhone 15 Professional Max will reportedly be manufactured utilizing TSMC’s N3B course of, however in accordance with Pu, Apple will swap to N3E subsequent 12 months when the chip is used within the iPhone 16 and iPhone 16 Plus.
N3B is TSMC’s authentic 3nm node created in partnership with Apple. N3E, then again, is the easier, extra accessible node that the majority different TSMC shoppers will use. N3E has fewer EUV layers and decrease transistor density than N3B, leading to effectivity tradeoffs, however the course of can present higher efficiency. N3B has additionally been prepared for mass manufacturing for a while longer than N3E, however it has a lot decrease yield. N3B was successfully designed as a trial node and isn’t suitable with TSMC’s successor processes together with N3P, N3X, and N3S, which means that Apple might want to redesign its future chips to make the most of TSMC’s developments.
Curiously, this mirrors a rumor shared on Weibo in June. The transfer was stated to be a cost-cutting measure that would come on the expense of lowered effectivity. On the time, it was thought unlikely that Apple would make such a drastic change to the A17 Bionic. The A15 Bionic chip within the iPhone 14 and iPhone 14 Plus is the next binned variant with one further GPU core than the A15 used within the iPhone 13 and iPhone 13 mini, so some cross-generational variations regardless of outwardly that includes the identical chip wouldn’t be extraordinary, however this could be successfully retaining the identical title on a basically completely different chip.
Apple was initially believed to be planning to make use of the N3B for the A16 Bionic chip, however needed to revert to N4 as a result of it was not prepared in time. It might be the case that Apple is utilizing the N3B CPU and GPU core design initially designed for the A16 Bionic for the preliminary A17 chips, earlier than switching to the unique A17 designs with N3E later in 2024.
