Apple chipmaker TSMC is apparently on track toward manufacturing its 2nm and 1.4nm chips, which could be found in future generations of Apple silicon-based products.
The manufacturing time frames for mass production of 2nm and 1.4nm chips have now apparently been determined: Trial production of the 2nm node will begin at in the second half of 2024, with small-scale production ramping up in the second quarter of 2025. Notably, TSMC’s new plant in Arizona will also join 2nm production efforts. In 2027, facilities in Taiwan will start to shift toward production of 1.4nm chips.
TSMC’s first 1.4nm mode has been officially dubbed the “A14” and will follow this “N2” 2nm chips. The N2 series is scheduled for mass production in late 2025, while an enhanced “N2P” node is expected in late 2026.
TSMC’s past, present, and future roadmap is presented as follows:
- iPhone XR and XS (2018): A12 Bionic (7nm, N7)
- iPhone 11 lineup (2019): A13 Bionic (7nm, N7P)
- iPhone 12 lineup (2020): A14 Bionic (5nm, N5)
- iPhone 13 Pro (2021): A15 Bionic (5nm, N5P)
- iPhone 14 Pro (2022): A16 Bionic (4nm, N4P)
- iPhone 15 Pro (2023): A17 Pro (3nm, N3B)
- iPhone 16 Pro (2024): “A18” (3nm, N3E)
- “iPhone 17 Pro” (2025): “A19” (2nm, N2)
- “iPhone 18 Pro” (2026): “A20” (2nm, N2P)
- “iPhone 19 Pro” (2027): “A21” (1.4nm, A14)
The M1 series of Apple silicon chips is based on the A14 Bionic and uses TSMC’s N5 node, while the M2 and M3 series use N5P and N3B, respectively. The Apple Watch’s S4 and S5 chips use N7, the S6, S7, and S8 chips use N7P, and the latest S9 chip uses N4P.
Each successive TSMC generation surpasses its predecessor in terms of transistor density, performance, and efficiency. In late 2023, it emerged that TSMC had already demonstrated prototype 2nm chips to Apple ahead of their expected introduction in 2025.
Stay tuned for additional details as they become available.
