On one hand it's nice to see low-power SoCs continuously raising the bar on GPU performance, even more for chinese IHVs like Mediatek and HiSilicon.
On the other hand, increasing GPU performance past Adreno 330's threshold seems like such a waste of die area and power envelope.
First, because none of these later SoCs can actually maintain their maximum performance for longer than a handful of minutes (or less), making it useless for anything but two or three runs of synthetic benchmarks. Second, because Android's 3D gaming market has pretty much stagnated for the last 2 or 3 years.
Meh...
