iPhone 16 series launch is still 11 months away.
Furthermore, Pu outlines his model-specific expectations in response to an email from MacRumors:
N3E is believed to be less expensive and has improved yield compared to N3B, as per TSMC. The standard iPhone 15 and iPhone 15 Plus currently ship with an A16 Bionic chip, so the A18 chip will be a big upgrade and will skip the A17-branded chip.
But then again, the iPhone 16 series launch is still 11 months away, and Pu appears to be making educated guesses with the marketing names. There are chances that the brand might tag the iPhone 16 series chips as A17, while the Pro model chip could be called A18 Pro.
Pu was the first one to report that Apple abandoned its plans for solid-state buttons on the iPhone 15 Pro models. He also rightly predicted that the Pro models would be equipped with an increased 8GB RAM and the Pro Max would see a higher starting price compared to 14 Pro Max.
