I think the interesting comparison will be between something like Tegra 5/Exynos 5 and this. Most scientific computing these days is CUDA, and getting something like cuBLAS onto this chip will be a struggle. The Exynos/Android combo has already lowered it's ability to interest me by not even accepting OpenCL as a first class citizen.

EDIT: Hopefully NVidia will give me CUDAndroid, so I have fun.
