TSMC hints 3nm iPhone 15 chip may prioritize battery life over performance

Apple’s chip supplier Taiwan Semiconductor Manufacturing Company (TSMC) today kicked off volume production of chips based on the new 3nm technology. The iPhone 15 Pro and iPhone 15 Ultra’s A17 chip will most likely also use this tech.

3nm chips will consume 30 to 35 percent less power at the same speed and the tech offers up to 1.6x logic density gain, meaning it will be possible to fit more transistors on chips, which should theoretically make them more powerful.

The 3nm tech is a full node strike from the 5nm tech which was used for the A14 Bionic, A15, and A16. The A16 Bionic chip which fuels the iPhone 14 Pro and Pro Max was based on an intermediary, 5nm-derivative node called 4nm.
