Speculation around the next iPhone line centers on a bold leap forward. Rumors suggest the iPhone 18 could arrive with a 2-nanometer A-series chip and a substantial RAM upgrade, sparking interest across markets in Canada and the United States. A report from MacRumors, citing a Chinese insider known as Phone Chip Expert, has highlighted these possibilities for the 2026 timeframe.
According to the source, Apple plans to launch the iPhone 18 with the A20 chip, manufactured by TSMC on its 2nm process. The report claims this model will ride on WMCM technology, replacing the current InFo approach. The switch is said to enhance the communication between the CPU, GPU and other chipset components, potentially delivering smoother performance and better power efficiency in real‑world use.
Additionally, the same source suggests the RAM would rise from 8 GB to 12 GB, a step that could improve multitasking, app responsiveness and on‑device graphics performance for demanding software and games.
Analyst Ming-Chi Kuo is quoted as saying that 2nm chips would likely power only the Pro versions of the iPhone 18, driven by the higher costs associated with the new process. TSMC is expected to begin mass production of 2nm chips by the end of 2025, with Apple positioned to be among the first customers to receive them.
For context, the current iPhone 16 models, including the 16 Pro, run on Apple’s A18 and A18 Pro chips built on a 3-nanometer process. In the Android ecosystem, 3nm devices are currently represented by chips such as MediaTek Dimensity 9400, the primary option available from that generation of silicon.
Earlier, reports noted the yet-to-be-announced Xiaomi 15 Pro being seen in the hand of Wang Xiaoyang, adding to the growing chatter about advanced chip choices in flagship smartphones for the near term.
If these rumors prove accurate, the move to a 2nm A20 would mark a notable efficiency and performance shift, particularly for the Pro tier. The real-world impact would hinge on manufacturing costs, supply chain reliability and how quickly Apple can scale production across its most popular devices. In any case, consumers and tech watchers should approach these claims with healthy skepticism while tracking official statements from Apple and its suppliers.
Overall, the chatter reflects a pattern of accelerated process nodes and memory upgrades in premium smartphones, underscoring Apple’s ongoing push toward higher efficiency and stronger on-device capabilities. The timeline, features and even the presence of a 2nm A20 chip remain subject to confirmation as Apple, TSMC and their partners finalize designs and production schedules for the iPhone 18 lineup.
