I'm not a GPGPU expert, but one thing that is easy to forget is that floating point types have a well-functioning integer subset. For example, on 32-bit computers it can be beneficial to use 64-bit doubles for extended precision in integer calculations. That said, when I've looked into potentially using GPGPU, the problem has been that branchy code is not a good fit.
