Hey all, I know this is puuuure speculation, maybe too much, but that’s what this thread is for, right?
iOS 19 is expected to be compatible with A13 devices, right? We still don’t know if the cut will be in the A12, A13 or A14, but it seems likely to be the A13.
As we all know, the A14 was a significant upgrade in the silicon: shift to 5nm, doubling the neural engine cores, brand new CPU and GPU cores… something that was further refined with the excellent A15 adding more caché and a much faster neural engine. The A15 was used by Apple in a lot of devices: iPad mini, Apple TV, iPhone 13, 13 mini, 13 Pro, iPhone 14… and I’m probably leaving some devices out.
Both the A14 and the A15 experienced an important increase on the GPU performance as well, going from 13300 metal points on the A13, to 16000 metal points on the A14 and 17200 in the A15.
But the A13 metal score (13300) was an even bigger jump if we compare it to the A12 GPU metal score, which was only 8800 points.
So the really big GPU performance increase came with the A13 SoC, and that’s why it makes sense to make it the lower SoC that supports iOS 19. I don’t think this time Apple will support iPadOS 19 on the iPad 8th gen with an A12, and if they do, I very much doubt the performance will be good.
What I really mean to ask is, keeping in mind that iOS 19 is coming with a big graphical redesign and a more taxing UI with more transparencies and Gaussian blurs and all that stuff, how do you think the performance on the oldest iPhones will be?
My guess, and I repeat this is just pure speculation, is that the A13 devices such as the iPhone 11 or SE2 will do fine if Apple really optimises the code for that minimum common denominator. I have a family member with an SE2, with the A13 chip, and according to him, the phone already drags it’s feet with iOS 18, so that doesn’t make me too optimistic. Hopefully I’m wrong, but I only see a good performance if Apple really optimises the code programming iOS 19 only for the A13 and newer chips.
On the other hand, I expect a very good performance on A16 devices and newer.
As you may know, I own an SE3 which is powered by an A15 SoC. How do you think iOS 19 performance will be on this devices
Apple should use this year’s software to remove a lot of old code, and center on the new hardware, A13 and onwards, to build the UI taking advantage of all the technologies this chips carry.
And why not? Make a more intense usage of the neural engine, especially in the A14 and upwards. Maybe it can be used as an auxiliary GPU help?
