Last year, Apple was the first and only smartphone manufacturer to offer a phone with a 3nm application processor (AP), the A17 Pro. To simplify the explanation, as the process node gets smaller, the size of the transistors in the chip gets smaller. This means more transistors can be placed on a chip, making the chip more powerful and more energy efficient. TSMC’s N3B 3nm first-generation node was used to manufacture the A 17 Pro chipset used to run the iPhone 15 Pro and iPhone 15 Pro Max. iPhone 15 and iPhone 15 Plus are powered by 4nm A16 Bionic, which is also included in iPhone 14 Pro models.
Tweet denies rumors that TSMC’s 2nm node will support iPhone 17 series
A report claiming that TSMC’s 2nm node, which will be used to manufacture the A19 Pro and A19 Bionic chipsets used in the iPhone 17 series, will be ready in time has been shot down by a social media post from China.A tweet posted by a Vietnamese freelance programmer named Nguyen Phi Hung. A translation of this social media post reads: “This is 1000000% false information. TSMC 2nm mass production will take until late 2026 and will not catch up to the iPhone 17 series in 2025.” .
If this is true, the Galaxy S26 series could become the first smartphone to use a 2nm chip if Qualcomm pays TSMC to use the 2nm node for its Snapdragon 8 Gen 5 SoC in 2026. On the other hand, Snapdragon 8 Gen 4 will be his first 3nm Snapdragon AP, so it is not clear whether Qualcomm will move from 3nm to 2nm so quickly.
If the naysayers are right and TSMC isn’t ready to build enough 2nm chipsets in time for next year’s iPhone 17 series, the 2nm process node could debut at Apple with the adopted A20 Pro and A20 Bionic chipsets. There is likely to be. In the iPhone 18 series.
