The standard iPhone 14 models will retain the A15 chip from the iPhone 13 but the Pro models will only have the A16 chip.

The 6.1-inch and the 6.7-inch will get the A.

Only two Pro models would upgrade to the A16 processor, while the 14 & 14 Max will remain the A15. All four new models will likely come with 6GB RAM, with the difference being LPDDR 5 (14 Pro & 14 Pro Max) vs. LPDDR 4X (14 & 14 Max). — 郭明錤 (Ming-Chi Kuo) (@mingchikuo) March 13, 2022

The two more affordable iPhone models retaining the same chip as the previous year could be a major new point of differentiation between the standard and Pro models. It's possible that Apple could only offer a new chip with the Pro models, before it trickles down to the two cheaper models the following year.

The standard model of the ‌iPhone 14‌ is likely to come with 6GB of memory, with the ‌iPhone 14‌ model having 4X memory.

The mini and the iPhone 13 Pro and Max have 4GB of memory. The amounts are the same as from the iPhone 12 lineup.

All models in the lineup will have 6GB of RAM, but the ‌iPhone 14 Pro' and ‌iPhone 14 Pro' will have more.

Jeff Pu of Haitong International Securities had claimed that the ‌iPhone 14 Pro‌ models will have the same amount of memory as the S22 Pu has a mixed record with Apple rumors. He said that 16-inch MacBook Pro and iPad Pro models with mini-LED displays would launch in 2021. Now that a more established analyst in the Apple space is saying otherwise, this may bring the 8GB RAM rumor into question.
