This is confusing Maybe someone in the comments below can clarify.
On the one hand, this comparison strongly suggests that the A18 and A18 Pro are literally the same chip, except the Pro version has an extra GPU core, which might be accounted for by the regular 18 being a binned version of the Pro with one less core making it through QC. So far, so good--this much seems clear. But then you go on to say that the 18 Pro chip also has all these other advantages:
• Larger caches
• Next-generation machine learning accelerators
• Improved memory bandwidth
• Better performance in demanding tasks and games
• An Advanced Media component, which enables Pro-exclusive features. This includes the ProMotion display with a variable refresh rate, Always-on display functionality, USB 3 speeds, and ProRes video recording.
Well... how could the regular and Pro A18 possibly be the same chip with all these differences? I don't see how the extra GPU core on the Pro chip could possibly account for all of that. It seems the only reasonable explanation is that these are similar but different chips and the regular version isn't simply a binned version of the Pro.
