I'll be curious if the new iPads with run a more powerful variant of the A8 (A8X?) to better handle the supposed split-screen multitasking and rumored 12.9" iPad.
I don’t think they’ll need it. The A7 pushes the 2048x1536 along just fine, and we know the A8 is faster yet (the SOC purportedly a has a 50% better GPU).
I think the thing that _is_ needed for managing multiple views/windows (and their objects/tabs/UI/state) is more RAM.
- TouchID
- A8
- 2GB RAM
- Improved display tech (like the iP6s)
- Drop the weight ~150-200g
New iOS 8.x iPad extensions for split screen, etc.
