Apple's new Retina iPad mini includes the same 64-bit A7 chip used in the iPad Air and the iPhone 5s



From MacRumors:

According to new Geekbench 3 benchmarks, the Retina iPad mini is running at 1.3Ghz, much like the iPhone 5s. The iPad Air, however, clocks in at 1.4Ghz, giving it a slight performance edge over both the iPhone 5s and the new mini. The Retina iPad mini scored a 1390 on the single-core test and a 2512 on the multi-core test, which was similar to the iPhone 5s score of 1399/2523, and lower than the iPad Air at 1466/2856.
