Last year, Apple announced its highly anticipated M3 chips fabricated on TSMC’s 3nm architecture. While the M3 Pro and M3 chips deliver enhanced performance over the M2 chips, the company has already started working on its next-gen Apple Silicon. A new report claims that Apple will likely be TSMC’s primary candidate for 2nm chips. TSMC’s 2nm chips will further improve the computational and graphical performance on the iPhone and Mac.
TSMC’s 2nm chips will offer further computational and efficiency gains for the iPhone and Mac
According to DigiTimes, sources familiar with the matter claim that Apple will be TSMC’s initial client for the 2nm chips for the iPhone, Mac, iPad, and additional devices (via MacRumors). The report will share further information on the supplier’s 2nm chips soon. TSMC is expected to mass-produce its 2nm chips in the second half of 2025. This means all products launching before the time frame will house chips based on TSMC’s 3nm architecture.
If you are unfamiliar with the technology, a lower nanometer count denotes a smaller transistor size. This means that more transistors can fit inside the processor. TSMC’s 2nm chips will boost performance and improve efficiency. With enhanced efficiency, we can expect better battery life on future Apple products, such as the iPhone and MacBooks.
Currently, Apple uses TSMC’s 3nm technology for chips designed for the MacBook, iPad, and iPad Pro models. Last year, the company announced the M3 Pro and M3 Max chips for the new MacBook Pro models. The company also uses TSMC’s 3nm chips for the iPhone 15 Pro’s A17 Pro chip. We have previously seen many tests that show the performance gains of the A17 Pro and M3 chips against their predecessors. Henceforth, we can presume that TSMC’s 2nm chips will further improve the mix.
In terms of numbers, the company’s transition from 5nm to 3nm chips brought a 10 percent gain in CPU performance, while GPU gains were as high as 20 percent. TSMC is working to upgrade the production capacity of the 2nm chips through two new facilities. The supplier will use GAAFET or gate-all-around field-effect transistors with nanosheets in contrast to FinFET. Despite a more complex production process, it will allow for smaller transistor sizes with lower power consumption.
We expect Apple to adopt the 2nm architecture in 2025, potentially with the launch of the iPhone 17 lineup. The same technology will also be available for the M-series of chips. TSMC is also silently working on its 1.4nm architecture, which is expected to be announced in 2027. Like the 2nm chips, Apple will potentially be the first to get the 1.4nm chips from TSMC. We will share more details on the subject, so stick around for more.
