Are the Radeon R4 or other APUs from AMD supported?

The Radeon R4 does appear in FAH's GPUs.txt file: https://apps.foldingathome.org/GPUs.txt
I don't have any firsthand knowledge of its folding performance.

If the device ID for a specific iGPU incorporated into one of AMD's APU products shows up in the GPUs.txt file, then it is supported. However that comes with some caveats.

First, for most if not all currently running GPU projects support for double precision calculations is required. I can not find definitive information on whether this is present for any APU.

Second, the processing power of the iGPU in an APU is limited by the TDP rating of the chip as a whole. For those who have successfully done GPU folding on one in the past, they often could make as much point wise by doing CPU folding instead.

There are some other issues such as driver support, and GPU switching in systems such as laptops that also have a higher powered discrete GPU..
