Apple just a few hours ago introduced the new iPhone 13 and iPhone 13 Pro devices. The novelties represent the budget and premium version of the new line of Apple in 2021. They received the same (in size) display, with distinctive characteristics: the premium iPhone 13 Pro model has a ProMotion-enabled screen.
In addition to other visible differences, which we have already talked about in the comparison of new products, the premium version has received one more advantage.
Analyzing the specifications on the official website, you can see that the same A15 Bionic chip has distinctive GPU characteristics. So the iPhone 13 Pro has five GPU cores when the iPhone 13 has four.
An additional core is apparently needed to process ProRes video.
