And what about Intel GPUs?

Even they are not the most powerful latest Iris GPUs are comparable powerful to 2-3 years old top Nvidia GPUs, 2-3 times more powerful then CPU, more power efficient then CPU, are available on all desktop and mobile Intel CPUs and their computational power is on top of CPU one...

I think with adoption of OpenCL for AMD GPUs it may be relatively easy to include support of OpenCL for Intel GPUs as well.

Note: It would be better to add AMD to supported platforms on Boinc project page where people are make first decision what project to support.

based on collatz average WU run times the intel 530 is 1/16th the speed of a stock 1080. 40m vs 2.5m
