TSMC, Taiwan Semiconductor Manufacturing Company, is the company responsible for the production of all Apple chips. From the A series used by iPhones to the M series used by Macs and iPads to the S series of Apple Watches. TSMC helped Apple become a pioneer in chip production The first company to use 3nm technology in the A17 Pro chip On iPhone 15 Pro and iPhone 15 Pro Max

However, the company will continue to develop its technology and future plans have been leaked. Plans with 2nm chip in iPhone 17 and Only a 1.4nm chip that can equip the iPhone 19. A theoretical “A21 Pro” if Apple doesn’t change the name first.

A17 Pro is the most advanced smartphone chip in the world

These are the nm of Apple iPhone chips

We may know practically once TSMC shows its future plans Technologies Apple will use in its next iPhone chips. Next year’s iPhone 16 will use a 3nm chip with an improved process called N3E. The iPhone 17 and 18 will then use a 2nm chip until 2027, when we will see a 1.4nm chip in the theoretical iPhone 19 Pro.

• iPhone XR and XS (2018): A12 Bionic (7nm, N7)
• iPhone 11 and 11 Pro (2019): A13 Bionic (7nm, N7P)
• iPhone 12 and 12 Pro (2020): A14 Bionic (5nm, N5)
• iPhone 13 and 13 Pro (2021): A15 Bionic (5nm, N5P)
• iPhone 14 Pro (2022): A16 Bionic (4nm, N4P)
• iPhone 15 Pro (2023): A17 Pro (3 nm, N3B)
• iPhone 16 Pro (2024): “A18” (3nm, N3E)
• “iPhone 17 Pro” (2025): “A19” (2nm, N2)
• “iPhone 18 Pro” (2026): “A20” (2 nm, N2P)
• “iPhone 19 Pro” (2027): “A21” (1.4nm, A14)

Each new node created by TSMC outperforms the previous one Transistor density, performance and efficiency. This means that the power of Apple’s chips increases every year, even if they maintain the same nm.

These technologies are also used in other Apple chips. Apple Silicon’s M1 series is based on A14 Bionic and uses TSMC’s N5 node, the M2 series uses N5P, and the new M3 chips use N3B. Apple Watch chips also use these manufacturing processes; The S4 and S5 use the N7 node, the S6, S7 and S8 chips use N7P, and the latest S9 chip uses N4P.
