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.
