A little change that Apple introduced with the iPhone 13 Pro and iPhone 13 Pro Max is that the A15 Bionic running in both models feature a 5-core GPU. This should result in some serious graphics performance increases, and according to the latest benchmark, it is a sizable difference when comparing last year’s iPhone 12 Pro and iPhone 12 Pro Max.

In the latest Geekbench 5 Metal score, the iPhone 13 Pro was benchmarked, and it obtained 14216 points in the GPU category. In comparison, MacRumors reports that the iPhone 12 Pro from last year with its A14 Bionic accumulated 9123 points in the same test. In short, Apple’s latest flagship is 55 percent faster, showing the significant gains the company worked on when deciding to opt for a 5-core GPU for the A15 Bionic.
