GPU Performance & Power
“Starting off with Basemark GPU 1.2, we’re seeing a 17% increase in peak performance relative to the iPhone 11 Pro and the A13 chip, which is a nice upgrade, but doesn’t tell the whole story. In the sustained performance figure after 30 minutes of running and when the phone reaches a thermal equilibrium, we see a 45% drop in performance. In this instance, it looks like the iPhone 12 Pro reached a lower sustained performance level than the iPhone 11 Pro which isn’t a great start, but that might change with differing workloads.”
