The most interesting part of this to me isn't the titanium or the camera (impressive as it looks), it's the GPU. They made a point of saying that the GPU had been completely ground-up re-designed, and I assume they're intending to keep scaling that up over the next few iterations. They didn't talk about it for very long, but that the phone is able to convincingly run AAA games, even at playable if not great frame-rat…
Assuming the trend of iPhone Ax chips showing up in Macs holds up, this would be late 2024 / early 2025 Macs and M4, not M3.
M2 is based based on A15, M3 is expected to be based on A16, M4 would be A17.
