Apps Reportedly Limited to Maximum of 5GB RAM in iPadOS, Even With 16GB M1 iPad Pro
Despite Apple offering the M1 iPad Pro in configurations with 8GB and 16GB of RAM, developers are now indicating that apps are limited to just 5GB of RAM usage, regardless of the configuration the app is running on.
The M1 iPad Pro comes in two memory configurations; the 128GB, 256GB, and 512GB models feature 8GB of RAM, while the 1TB and 2TB variants offer 16GB of memory, the highest ever in an iPad. Even with the unprecedented amount of RAM on the iPad, developers are reportedly severely limited in the amount they can actually use.
Posted by the developer behind the graphic and design app Artstudio Pro on the Procreate Forum, apps can only use 5GB of RAM on the new M1 iPad Pros. According to the developer, attempting to use anymore will cause the app to crash.
There is a big problem with M1 iPad Pro. After making stress test and other tests on new M1 iPad Pro with 16GB or RAM, it turned out that app can use ONLY 5GB or RAM! If we allocate more, app crashes. It is only 0.5GB more that in old iPads with 6GB of RAM! I suppose it isn't better on iPad with 8GB.
Following the release of its M1-optimized app, Procreate also noted on Twitter that with either 8GB or 16GB of available RAM, the app is limited by the amount of RAM it can use.
As of now, all M1 iPads have the same amount of RAM available. As soon as we have access to more, we’ll pass that on to you, too — Procreate (@Procreate) May 28, 2021
The previous maximum RAM in an iPad was last year's iPad Pro which featured 6GB of RAM, regardless of storage configuration. Given, a 5GB limit on apps imposed by iPadOS wouldn't necessarily ring any alarm bells as developers would have access to the majority of the available memory. Although, with the M1 iPad Pro, developers cannot tap the full potential of the available hardware.
The added RAM, especially in the higher-end 1TB and 2TB models, will still benefit the user by allowing them to keep more apps open in the background. iPadOS itself can access the M1's entire pool of unified memory, while apps can reportedly only access 5GB of it.
iPad users have long voiced the mantra that iPadOS doesn't take full advantage of the available hardware and potential of the iPad Pro, and now thanks to the M1 chip inside of the iPad Pro, that's certainly more of a case.
Apple will hold its Worldwide Developers Conference on June 7, where it's expected to announce iOS 15, watchOS 8, macOS 12, tvOS 15, and iPadOS 15. Bloomberg has reported that iPadOS 15 will include the biggest redesign to the iPad homescreen since the iPad first launched, including the ability for users to place widgets anywhere on the grid.
We've contacted Apple for clarification regarding the amount of RAM apps can access and will update this post if we hear back.
