I wish to programatically measure the power of this GPU. (I don't want a tool). Is there an API, or a developer guide for accessing the registers containing this information?
Does this GPU contain an onboard power sensor?
I've white-listed you, so you should be able to post in the appropriate forum. I believe the AMD ADL API allows you to measure certain GPU parameters, but I'll leave the specifics to the OpenCL experts to answer -- moving your question to that forum.
