the benchmarks u showing is the MSM8660 clocked at 1.5ghz. i suppose that y the it perform better.
but, the benchmarks u showing is openGL which mainly showing the performance of the gpu rather than cpu.
So, i would say all the current dual core Soc perform almost the same in term of cpu as all used cortex A9.
what we actually need to see is the gpu.

what i mean is that most of the soc cpu perform the almost the same, so the only difference is gpu. that y we need to look into the gpu.
