They didn’t throttle anything. The chip in the iPhone 15 simply isn’t capable of the full speed.

While true, it's interesting that the SOC in the "pro" models have started adopting a "pro" branding for the first time.

So it's quite likely that they will give the equivalent processor minus the "pro" features to the base model next year. I am betting that USB 3.x is a "pro" feature.

No, they tend to use last year's Pro chip in this year's base model. The A16 only supported USB 2.0 speeds last year in the iPhone 14 Pro model (despite the iPads showing us that Lightning does support USB 3 speeds), and it's what's in this year's iPhone 15 base model.

The A17 supports higher speed through the USB Bus, so there's no reason to hold that back for next year's base model.

Yes, I am aware.

The thing that's notable this time is that the pro chips are branded with "pro". This absolutely means that next year the base models will get the same chip except it's stripped of some features and its "pro" branding. The question is which features. I am betting it's USB 3.0.

Actually... that's unlikely.

This year's "Pro" processor is fabricated on TSMC's 3nm N3B process that has very low yield rates - Apple is apparently taking up 90% of the global production capacity for N3B fabrication even though they only use it with relatively low volume "Pro" chipsets.

They'll surely have better yields next year, but it would still be nowhere near enough to put them in the mainstream iPhone models. TSMC has said they have a new process (which will require new chip designs) online now, and that's what next year's mainstream iPhones will use. Manufacturing might have already started (for a late next year launch date).
