So, regardless of the configuration, the application cannot use more than 5 GB of RAM, and these limitations are inherent in the iPadOS operating system. Attempting to use more memory will cause the application to crash.
Moreover, this applies to the iPad Pro with both 8 GB and 16 GB of RAM. Of course, 5 GB is already a rather large amount, but everything is learned by comparison: last year’s iPad Pros have a limit of 4.5 GB, but they have only 6 GB of RAM.
In any case, developers cannot fully unleash the potential of the available hardware, namely the M1 chip. Users have long been saying that iPadOS is not taking full advantage of the iPad Pro’s potential, and now it seems more relevant than ever.
