Something doesn't add up for me. Why does Apple make a 64 bit A7 processor and not increase the ram on any IOS devices beyond 1 GB? If Apple was truly moving towards IOS devices with 4 GB+ of ram you you would think they would have started moving in that direction. My only conclusion is that maybe Apple really does have bigger plans for their custom Arm processor lineup. Maybe the rumors are true about an Arm powered Macbook Pro where support for 4 GB+ of ram would be required.
