Apple may reduce the performance of the 3nm A17 Pro processor due to massive overheating of the iPhone 15 Pro::The problem of overheating of iPhone 15 Pro and Pro Max smartphones is becoming widespread. It is possible that Apple will be forced to take the unpopular step of reducing the performance of the latest 3nm A17 Pro chip.

I could see a case made for the test units having much better heat transfer and once mass produced the silicon lottery inevitably made some chips run hotter. But those variances are not massive, so it would've already had to run pretty hot. IDK

When developing a product you order "process corner" chips that are primarily used for testing the memory timings (through a process called Shmoo) to make sure it is stable. The "FF" class of these chips are also useful for testing thermals as they draw the maximum power you will see with the silicon lottery. So assuming Apple did this properly they should have had a good idea of what the product temperature is at the operating temperature extremes.

Interesting, so SOP would rule that out too. I didn't know this.
