Why the iPad Pro Has a 5GB RAM Limit

For the vast, vast majority of apps and workflows — the vast majority of people — not only won’t a 5 GB RAM limit on iPad Pro apps ever be an honest-to-Jobs, actual, real-world type problem, but odds are you won’t even notice it. Much less be irked by it. At least if people didn’t publish first, research second… or never. Which irks me, obviously.

For some very specific apps, though, you absolutely will notice. iPad apps like Procreate that can benefit from more layers, which do indeed require more RAM.

It’s for those very specific types of iPad apps that Apple’s adding this very specific new entitlement. So they can check system resources, see how much extra memory is currently available, and then request and get more of that memory to use.
