The iPad Air 2’s Extra GB of RAM

Display aside, another hardware change that I noticed in my iPad Air 2 is the extra RAM Apple put in this year. Pocket Gamer’s Mark Brown ran some tests:

To see how things have changed, we rebooted an iPad Air and an iPad Air 2, and then loaded monster memory hog XCOM: Enemy Unknown. We then started opening and using apps to see how much we could get done before iOS forcibly removed XCOM from memory.

Apple’s handy OS X tool Instruments lets you keep an eye on what your iPad is doing, so we could see the exact moment that XCOM was killed off like a Sectoid on the receiving end of a shotgun.

Check out his gallery of screenshots to see how much an extra GB of RAM can help. In my case, the iPad Air 2 keeps more Safari tabs in memory without aggressively reloading when I switch between them, and apps generally stay active for longer periods of time. The end result is a faster experience as I see less apps being removed from memory – a change that I particularly appreciate when I’m switching between Safari and a bunch of other apps for research or file management tasks.
