I did some more digging online and came across these benchmarks and OpenCL environment variables. This is the link to the GPU on the A10-4600M with an integrated HD 7660G GPU. http://clbenchmark.com/device-environment.jsp?config=12100910 it can be seen here that it supports cl_amd_fp64 and cl_khr_fp64 OpenCL environmental variables. I don't know what the performance would be, probably low, but at least it will perform the operations.
The older Llano based APUs did not support fp64, but Trinity and I suspect Richland will. Based on this, I will be purchasing a Richland based laptop as soon as I can find one.
