iPhone 12 Pro and iPhone 12 Pro Max models are equipped with 6GB of RAM, while the lower-end iPhone 12 and iPhone 12 mini models have 4GB of RAM, according to plist files in the Xcode 12.1 beta viewed by MacRumors.
These plist files have accurately revealed the amount of RAM in several generations of iPhones, and for good measure, a seemingly legitimate Geekbench result for the iPhone 12 Pro also lists 6GB of RAM for that device. By comparison, the iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max are all equipped with 4GB of RAM.
With the increased RAM and a faster A14 Bionic chip, iPhone 12 Pro models should have significant performance improvements. The benchmark result for the iPhone 12 Pro shows that the A14 chip has roughly the same single-core performance as in the new iPad Air, although its multi-core score is significantly lower. This could be due to Geekbench being run on the iPhone shortly after it was set up, which can result in temporarily lower scores, but we’ll have to wait for further benchmark results to know for certain.
