Data from the Xcode 14 beta development environment, which includes an SDK for all Apple platforms, suggests that all Apple iPhone 14 phones received 6 GB of RAM. For iPhone 14 and iPhone 14 Plus, this is a step up from its predecessors.
Recall that in the iPhone 13 series, only two top models have 6 GB of RAM – the iPhone 13 Pro and iPhone 13 Pro Max, while the iPhone 13 and iPhone 13 mini have only 4 GB each. In the new series, Apple has equalized the parameters of older and younger models.
Apple does not officially talk about the amount of RAM – usually you can find out about this only by running a benchmark. iPhone 14 Pro already tested in Geekbench, and it does indeed have 6 GB of RAM. But the information obtained using Xcode has been repeatedly confirmed in the past, so even now there is no reason not to believe this data. However, the new iPhones are still divided into two categories based on the parameters of the hardware platform: the iPhone 14 and iPhone 14 Plus use the Apple A15 Bionic SoC, while the iPhone 14 Pro and iPhone 14 Pro Max received the A16 Bionic SoC.
