In the battle for speediest tablet, there can be only one victor. In our side-by-side tests of every single full-sized iPad generation ever made, not surprisingly, the Apple iPad Air makes a strong case for supremacy.
Since Apple introduced the iPad in 2010, it’s been continually upping the ante on its processor. The very first iPad featured a custom-built A4 mobile CPU, which ran at 1 GHz. The iPad 2 got an upgrade to the more powerful A5 chip. It, too, was clocked at 1 GHz
But, as with all Apple’s ARM-based chips, the performance was more than the sum of its Hertz.
