GPU power parameters explainations?
#1
Hi

I see that my mobile GPU has these measurements: 
- GPU Core Power
- GPU Memory Power
GPU Power

The "GPU Power" seems to be a lot lower than the GPU Core Power and probably it's a part of the "Core Power"
What's the difference between the two reds? anyone knows?

Thanks

Which GPU do you have? Can you provide more exact numbers - idle and under load ?

Well, this is interesting Smile
I have tested a lot of AMD GPUs and never saw the "GPU Power" being reported. This value is actually retrieved via AMD's 'official' interface, while "GPU Core Power" and "GPU Memory Power" are read using a different proprietary method. Unfortunately AMD doesn't provide more information about the meaning of those values, but since the "GPU Power" value is read using an 'official' method and because that value seems much more reasonable than the other two on your GPU, I'd trust the "GPU Power" value.

It's also possible that the "GPU Core Power" and "GPU Memory Power" might require some adjusting for your GPU.
Can you please provide the HWiNFO Debug File of your machine? Also it would be helpful if you could provide values of all GPU parameters while they are stable (i.e. stabilized when GPU is idle, or under a constant load). I'll then have a look if it's possible to fix that.
