Head-to-Head: iPad Mini With Retina Vs. Kindle Fire HDX 8.9


Memory And Storage

Apple doesn't publish the amount of RAM in its devices and reports are mostly silent too. But we'd expect at least the same 1 GB that's on iPhone 5S considering it, too, will be running 64-bit apps. Amazon proudly declares the 2 GB of RAM Fire HDX has to run apps atop Fire OS 3.0 (which itself runs atop Android 4.2.2). For storage, Apple adds a 128-GB model to the 16-GB, 32-GB and 64-GB varieties from before. Kindle Fire HDX comes with 16 GB, 32 GB or 64 GB.
