Apple's pursuit of cutting-edge semiconductor technology has led to impressive advancements in its chipsets over the years. However, recent reports suggest that Apple's timeline for adopting 2nm chips might not be as quick as expected, with the next big leap in processor technology possibly coming later than anticipated.
A Shift in the Processor Development Cycle
While Apple typically follows a two-year process node cycle for its chips, there has been a notable change in recent years. For instance, Apple’s 7nm and 5nm chips each spanned two years, but it seems Apple may extend its reliance on 3nm chips for a third year, postponing the shift to 2nm.
In fact, it’s not the first time Apple has used the same manufacturing node for three consecutive years. For example, Apple introduced the A14 chip in 2020, marking the first 5nm-based Apple Silicon built by TSMC. The A15 chip followed in 2021, also using the 5nm process, while the A16 chip, marketed as a "4nm" process, was actually a refinement of the 5nm node rather than a true transition to a new technology.
Despite the marketing of the A16 as a "4nm" chip, it’s essentially an enhanced version of the 5nm process, with TSMC's naming scheme expanding the 5nm family to accommodate various customer requirements, such as N5P, N4, N4P, and N4X for high-performance computing (HPC) and automotive applications.
Why the Delay in 2nm?
According to industry insiders, the pace of new process node development has slowed down, with new nodes taking around three years to mature. Apple’s first 3nm processor, the A17, launched in 2023. Based on the current development cycle, it’s expected that Apple will continue using the 3nm process, with the third iteration of 3nm technology (likely N3P) for the iPhone 17 in 2025.
What Does This Mean for the 2025 iPhone?
While there were early speculations that Apple might adopt TSMC’s 2nm process for the iPhone 17 series, well-known market analyst Ming-Chi Kuo suggests that Apple will instead stick with the 3nm process, using the advanced N3P technology for the 2025 iPhone models. As for the iPhone 18 series in 2026, that’s when we can expect to see the first devices powered by TSMC’s 2nm process. However, cost considerations may mean that not all iPhone 18 models will feature the 2nm chip, with the base models potentially continuing to use the 3nm N3P or even the next iteration, N3X.
The 2nm Timeline and Apple's Future Chips
TSMC plans to begin risk production of its first 2nm chips (N2) in 2025, with mass production slated for 2026. While this timeline aligns with the iPhone 17 launch, it appears Apple will take a more cautious approach. Considering that Apple only adopted 3nm chips in 2023, the company is likely to wait until 2026 before introducing the 2nm technology into its products. Therefore, the Mac and iPad M5 processors, which will debut in 2025, are also unlikely to feature 2nm technology.
Conclusion: The 2nm Wait
In summary, while TSMC’s 2nm process will be available for production in 2025, it seems Apple will hold off on using it in the 2025 iPhone 17 series. The iPhone 18 series in 2026 is more likely to feature the new 2nm chips, although the basic models may continue to use the 3nm N3P or N3X nodes. The wait for Apple’s 2nm processors will extend into the second half of the decade, reflecting the increasing complexity and cost considerations involved in semiconductor manufacturing.
