Apple had strict limit of 5Gb, they now give flexibility for app/developer to request more but it isn’t guaranteed. iOS/ipad OS have very aggressive memory management for background apps. How long do you plan to keep your iPad Pro?Didn't know about the ram limitation and request from apps. I have the option to pay for 16 GB. I want to be smart and choose what suits your needs and is the most affordable.
I can imagine there is a difference between iOS and Mac OS when it comes to memory. We can't see how much RAM each process and app takes on iPad iOS like you can on Windows and Mac.
