"Finally, Apple has fixed one aspect of the 9.7-inch Pro that drew complaints from the professional crowd last year: the 10.5-inch Pro comes with 4GB of RAM, same as the 12.9-inch version. RAM doesn’t directly speed up iDevices, at least not like it does in regular computers, but it helps keep things running smoothly by allowing more tabs and apps to stay loaded in memory at once before Apple begins purging them. There are also signs that iOS 11’s multitasking is slightly more versatile on iPads with 4GB of RAM, allowing as many as three active apps and a picture-in-picture window onscreen at once."
