For scientific workloads, double precision is a must have. The 7 digits of FP32 is not enough. In my lab, we haven't updated our Kepler based GPU since 2013 for this reason.
Since I don’t plan to run any DNA analysis or fintech simulations on my smartphone anytime soon, I am very satisfied having FP32/FP16 precision in mobile right now. And so should you.
You are right, I thought vessenes meant: "FP64 seems like a very small use case for most of the parallelized workflows I can imagine" for any platform.
