Though Apple usually follows a two 12 months cycle with course of nodes, with the 7nm and 5nm processes lasting two years every – it appears extremely probably that Apple is about to make use of the 3nm course of for a 3rd 12 months in a row with the upcoming iPhone 17 lineup. There are a variety of causes for this, which we’ll be delving into.
3 12 months silicon cycle
Technically talking, this isn’t the primary time that we’ve had the identical course of node for 3 years in a row, it’s simply that it was hidden the primary time.
Apple launched the A14 chipset, the primary technology Apple Silicon constructed on TSMC’s 5nm structure in 2020, adopted by the A15, constructed on the second technology 5nm course of, in 2021. After that, Apple launched the A16 chipset with iPhone 14 Professional in 2022 – which was constructed on a “4nm” course of.
Nonetheless, the truth is, whereas it’s branded as 4nm to the general public, TSMC refers to the N4 processed used within the A16 Bionic as a part of the “5nm expertise household”:
TSMC continues to increase its 5nm expertise household to fulfill numerous buyer calls for. These embody N5P, N4, and N4P for higher energy, efficiency and density, N4X, a course of tailor-made for prime efficiency computing (HPC) functions, and N5A for automotive functions.
Subsequent technology silicon fabrication merely isn’t being developed as quick because it used to, so we’re actually on a 3 12 months launch cycle now. The truth is, we solely noticed the primary 3nm chips in Apple gadgets in 2023 as a result of Apple used an early manufacturing 3nm course of (N3B) that the majority corporations selected to skip over.
When to count on 2nm: iPhone 17 vs iPhone 18
Whereas preliminary rumors instructed that the iPhone 17 can be constructed on the innovative 2nm manufacturing course of from TSMC, that not appears to be the case, and provide chain analyst Ming-Chi Kuo believes that we’ll be seeing the third technology 3nm course of, N3P, with the iPhone 17 lineup:
The processors for 2025 iPhone 17 fashions might be made by TSMC’s N3P course of/3-nanometer expertise. The processor for 2026 iPhone 18 fashions is anticipated to make use of TSMC’s 2-nanometer expertise. Nonetheless, resulting from value issues, not all new iPhone 18 fashions could also be outfitted with a 2-nanometer processor.
As Kuo acknowledged, the iPhone 17 lineup received’t be utilizing 2nm, and you must probably maintain out for the iPhone 18 Professional fashions if you happen to’re searching for the newest and best in silicon fabrication.
It appears probably that the bottom iPhone 18 fashions will persist with 3nm chips, so we might both see the identical third technology N3P course of because the iPhone 17 lineup, or maybe the fourth technology N3X course of. Time will inform.
2nm manufacturing
TSMC is anticipated to start danger manufacturing of the primary technology 2nm course of (N2) sooner or later in 2025, with quantity manufacturing happening later within the 12 months. This timeline would theoretically line up for the iPhone 17 launch, however for one motive or one other, Apple has chosen to carry out.
This isn’t out of the bizarre, as the primary technology 3nm course of additionally started quantity manufacturing in late 2022, however Apple nonetheless elected to not undertake it for one more 12 months.
Apple additionally isn’t anticipated to undertake 2nm for the M5 household of chips in Macs and iPads. These chips will even use the third technology 3nm course of, in accordance with The Elec (through MacRumors).
It’ll be 2026 on the earliest earlier than we see 2nm chips in Apple gadgets, in accordance with present reporting.
