Yeah I thought it was a NPU tops issue that’s keeping it off the 17 non pro. However since it runs on a M1 I think it’s more to do with needing 8GB RAM to fit the model.

That’s incorrect. M-Series chips are used in Macs and iPads. iPhone uses A-Seres.

The iPhone 15 runs an A16 Bionic chip, and the iPhone 15 Pro runs an A17 Pro chip, as I wrote in my above comparison.

The A16 Bionic has as Neural Engine capable of 17 TOPS but 6GB of RAM.

The M1 had a Neural Engine capable of just 11 TOPS but all M1 chips have at least 8GB of RAM.

So the model could run on an A16 Bionic if it had 8GB of RAM as it has 54% more TOPS than the M1, but it only has 6GB of RAM. Apple have clearly decided that a model small enough to fit just wouldn’t give good enough results.

Maybe as research progresses they’ll find a way to make it work with a model with fewer parameters but I’m not going to hold my breath.

There are no M1 devices with less than 8GB of RAM.
