Somehow this is two steps back from MT6752.
Cortex A53 rev 1 vs rev 2 in MT6752
ARM MALI T720 MP2 vs MALI T760 MP2 (around 30% slower is T720). This actually make this SoC by all means worse than S615.
Who ever come up & did this is retarded!
I have a feeling Qualcomm is in for a world of hurt until they can get their custom 64-bit SoC out, as it seems like very few are going to use their current gen 64-bit. Though, I guess they do have a fairly big pile of cash to get them through 2015.
I don't think their patents will be as relevant as they were up until the SD805, as that was mostly integrated LTE. The likes of Intel has made alternatives available for them, giving them a stronger negotiation stance.
