AppleInsider and Cult of Mac both report claims that the iPhone 18 Pro models will use Apple’s next-generation A20 and A20 Pro chips, with performance and power-efficiency improvements tied to TSMC’s 2-nanometer manufacturing process. The reports describe the A20 as arriving first with the iPhone 18 lineup, including the A20 Pro, and suggest a move to 2nm could enable notable gains.
Both outlets frame the expected improvements as a result of a die shrink, which typically allows more performance per watt compared with prior process nodes. They also note that any specific magnitude of the upgrade depends on the accuracy of leaks or rumors. While AppleInsider adds that Apple would “pay dearly” for the improvements—implying higher costs—Cult of Mac focuses more on the possibility of a “major” boost in chip performance and efficiency for iPhone users. Neither source presents verified production details or confirmed performance benchmarks.
Overall, the story centers on unconfirmed reporting about the A20/A20 Pro’s manufacturing basis and the potential impact on future iPhone 18 Pro devices.
