That my friend's jumbo sized iPad Pro casually outruns my desktop, is a little perturbing from the perspective that my Core i5 is getting pretty damned old. But at least, it still does its real job pretty well and that job kind of demands a massive GTX card.
That old reviews of the Air 2 suggest similar browser performance to my Snapdragon 820 on the other hand, is both comforting and annoying.
Trying to make some comparative analysis from old data is also tricker. People's choices in benchmarks have changed over the years, and in the case of iPads usually moot as you traditionally had no real choices, hahaha; meanwhile those of us in Android land, long had a lot more products to choose from.
