Why is ML Super Resolution SO MUCH faster on my iPhone 13 Pro Max than my iPad Pro?

Is something not working like it should? Let us know.

I just got Pixelmator Pro for my iPhone 13 Pro Max and ML Super Resolution is lightning fast on it, like only 10-15 seconds. My iPad Pro, however, takes up to 40 seconds to upscale an image. Is there something wrong with my iPad? Why is my phone so much faster than my iPad? Maybe the neural engine is just more advanced in the A15 chip than the A12Z, but I find it hard to believe it is THAT much faster. If it’s a bug, can you patch it?

The A12Z has an 8-core neural processor, whereas the A15 has a 16-core neural processor, which is also faster, so this is pretty much expected I'd say. ML processing speeds are increasing quite significantly with each new device.

that would explain my my iPad feels slow. I don’t want to upgrade just yet

I mean, it's still a super-powerful device, it's just these ML features (which require huge amounts of computation) are slower, so I totally get you not wanting to upgrade. But at least now you know it's not a bug. :sweat_smile:

I was really hoping it was a bug, because it’s frustrating having a $2000 iPad take almost a minute to upscale images. I’m personally waiting for an OLED iPad Pro before I upgrade, which is almost certainly going to take a while

Point taken!
