iPad mini 4

The iPad mini 4 is faster, thinner, taller, and lighter than the iPad mini 3, boasting a 30% faster CPU and 60% faster graphics, which it replaces. That’s due in part to the 1.5 GHz A8 processor and in part to having 2 MB of system memory.

The big difference between the iPad mini 2 and iPad mini 3 is the addition of Apple’s fingerprint sensor in the Home button of the Mini 3. The small difference is the addition of gold to space gray and silver finishes.

2nd Generation iPad mini

At first glance, you’d think this was the original iPad mini, but the 2G iPad mini (unofficially iPad mini 2) runs Apple’s A7 processor and has a Retina Display. The 64-bit A7 takes performance far beyond that of the earlier A5-based iPad mini.
