For AMD GPUs (search for "double precision"): http://en.wikipedia.org/wiki/List_of_AMD_graphics_processing_units
For NVIDIA GPUs it's better read about the architecture detailds: http://en.wikipedia.org/wiki/Fermi_(microarchitecture) http://en.wikipedia.org/wiki/Kepler_(microarchitecture)
For intel IGPs: it's a waste of time searching for Intel IGPs FP64 support....

 

EDIT: for nvidia GPUS I found this: https://developer.nvidia.com/sites/default/files/akamai/cuda/files/NVIDIA-CUDA-Floating-Point.pdf

Please note that it speaks about CUDA support.

I appreciate the help.  I went through the links you posted and didn't quite find what I was looking for.  I was thinking more along the lines of CardCaps.xls but a bit more up to date.

 

That said I've decided to use fixed point math instead of doubles.  There's a few key functions (namely modf, or an equivalent) that don't support doubles, so I can't use them anyways.
