They compared this to A7 in the presentation - any idea how this compares to the A8?
Need benchmarks, but I think it would be safe to assume 5-10% faster than the A8 on CPU intensive tasks if just because a (likely) higher clock speed. GPU is harder to judge, but I'd think somewhere in the neighborhood of 10-20%.
The likelihood is 'similar' The A5X chip in the third gen iPad was simply a beefed up 5 designed to handle the iPad's larger screen size.
It has a billion more transistors than the A8
The A5X has the same computational abilities as the one used in the iPad 2. Its only difference was a slightly different GPU with another core.
Sorry, you're quite right - I mean to handle the Retina Display rather than larger screen - my bad.
My guess is that the A7 wasn't quite enough to handle the Retina Display in the A7, although it wasn't bad, certain animations, such as launching Siri did lag a little. I think that's why it's an A8X. With 250% faster GPU over A7, it's crazy fast.
Those are way too low.
It is easy to do the math as in iphone6 a8 was 25% faster in cpu and 50% faster in gpu compared to a7 in iphone5s
For iPad Air 2 the numbers are 40% faster in cpu and 2.5x in gpu compared to a7 in iPad air.
Also iPad air a7 was approx 10% faster than the a7 in the iphone5s in cpu
Put it altogether and we have a8x compared to a8
CPU about 20%
