They might not have grown in size, but Apple's hot-out-of-the-oven new iPads are surely top notch when it comes to internal hardware prowess (compared to their predecessors, that is). Both tablets have been refreshed with an Apple A8X chipset, a custom version of the 64-bit Apple A8 SoC found inside the Apple iPhone 6 and iPhone 6 Plus, which is a first for Apple and cements the future-proofness of its brand new tablets.
Frankly said, the improvements are not many, but they are mostly spot on. As we said, they sport most of the bells and whistles that the latest two generations of iPhones had in store, such as the Touch ID fingerprint sensor under the home button, support for Apple's Pay on-the-move payment system, and several other novelties. Then again, are these improvements enough to deem the new iPad Air vastly superior to its predecessor? Or the new slate is nothing but a minor improvement over last year's Apple iPad Air?
We decided to pit the new iPad Air 2 against its prequel and see what's happening specs-wise. We've also thrown in the older Apple iPad 4 for a good measure as well.

I bet the new ipad can open more than 3 safari tabs without constantly refreshing the ones not in use
