The website claims "iPhone 5e" will represent an "enhanced" iPhone 5s and replace the latter in Apple's smartphone lineup once released. iPhone 5e would be Apple's new entry-level handset.

Japanese website Mac Otakara also said the new 4-inch iPhone will have an A8 chip, without disclosing potential RAM, while Chinese website MyDrivers said the device will have an A9 processor and 2GB of RAM.

KGI Securities analyst Ming-Chi Kuo also said the 4-inch iPhone will have an A9 chip in a research note to investors, but that appears to be more of a prediction rather than supply chain evidence.
