Developer Hamza Sood confirmed the rumors around the iPhone 6s and iPad Pro RAM specifications.
The developer found out it by running a small test application containing three images, which are included or excluded dynamically based on the amount of RAM available. Sood explains how he hacked Xcode asset catalogs to discover the information. Asset catalogs are as a rule used to serve various images for 1x, 2x and 3x screen scales. The developer instead made the asset loading depend on the memory capacity of the different devices. The test confirms that the iPhone 6s has 2 GB of RAM, up from 1 GB in the iPhone 6, and the iPad Pro has 4 GB RAM, a 100% increase from the 2 GB in the iPad Air 2’s A8X chip.
The iPhone 6s and iPhone 6s Plus have previously been said to include 2GB of RAM. Meanwhile, Adobe issued a Creative Cloud press release last week that revealed the iPad Pro had 4GB of RAM, but removed the mention just hours later.
This is the first time that the company has made an iPhone with more than 1GB of RAM, and it joins the iPad Air 2 as the only device to have 2GB of RAM.
The iPad hit 1 gigabyte with the iPad 3 in 2012. That was finally increased to 2 gigabytes with the iPad Air 2, though the device did switch to speedier LPDDR3 in the interim.
Adding 4 gigabytes of RAM to the iPad Pro could mean that the company anticipates heavy use of side-by-side multitasking on the larger device.
