Apple announced the new iPad mini 6 alongside the iPhone 13 series just a few days ago. The iPad mini received the long-awaited redesign we were expecting. It comes with slimmer bezels, support for Apple Pencil 2, relocated Volume buttons, USB-C, and faster internals. The new iPad mini 6 now comes with an increased 4GB of RAM which will allow for seamless multitasking capabilities. However, the iPad 9 rests at 3GB. Scroll down to read more details on the subject.

Other than 4GB of RAM, the new iPad mini 6 comes with the all-new A15 Bionic chip, the same as the latest iPhone 13 models. While Apple does not believe in citing the amount of RAM it has bestowed the iPad mini 6, it was revealed via the strings contained in Xcode 13 beta (via MacRumors). However, Apple's cheapest iPad 9 features only 3GB of RAM.
