iPhone 15 Pro's A17 Bionic Chip Could Be 35% More Energy … – MacRumors

The A17 Bionic chip for next year’s high-end models of the iPhone 15 lineup could be 35% more efficient compared to current iPhone processors thanks to the use of newer 3nm chip process technology.

Apple is expected to adopt the smaller 3nm process technology for the 2023 ‌iPhone‌ chip, destined to be the A17 Bionic. The current A16 Bionic chip uses TSMC’s 4nm process, which offers improved efficiency and performance compared to the A15 Bionic chip based on the 5nm process from the year prior.
Mass production of TSMC’s 3nm process began this week, and Bloomberg cites TSMC’s chairman Mark Liu as saying the newer process will require 35% less power while also providing better performance than its previous 5nm process. Apple is expected to be TSMC’s biggest customer of the 3nm process, reportedly using it for the upcoming M2 Pro and ‌M2‌ Max chips and the A17 Bionic for the iPhone 15 Pro.
Last week, a report uncovered new challenges Apple faced while developing the A16 Bionic chip for the iPhone 14 Pro and ‌iPhone 14 Pro‌ Max. According to the report, Apple had more aggressive plans to further improve the GPU on the chip, calling it a “generational leap.” Apple initially wanted to include ray tracing for the A16 Bionic’s GPU, but those plans failed after the chip overheated, leading to poor battery life. Ultimately, Apple changed plans last minute and included a GPU based on last year’s A15 Bionic chip.
The lack of a more advanced GPU in the A16 Bionic chip could mean we see more considerable improvements with the A17 Bionic chip on high-end ‌iPhone 15‌ models next year. For the first time with the iPhone 14 lineup, Apple only gave the higher-end Pro models the newer A16 Bionic chip while keeping the lower-end models with the one-year-old A15 Bionic chip. That same precedent is expected to continue next year, with only the higher-end models of the lineup gaining the A17 Bionic while the rest of the lineup will use this year’s A16 Bionic chip.
Details on the ‌iPhone 15‌ and higher-end ‌iPhone 15 Pro‌ and possibly ‌iPhone 15‌ “Ultra” are scant, but we are expecting improvements with the cameras, including a periscope lens, the expansion of Dynamic Island to all models of the lineup, and more.
