Re: GPU Power Consumption

Hi Samy,

Looks like Catalyst driver is installed now.

You can try following again:

  1. When system is in idle state.
  2. When system is loaded with only CPU intensive application
  3. When system is loaded with OpenCL program

regards,

Re: GPU Power Consumption

Hello,

Seems like the minimal resolution of power measurement profiling is 20ms... What is the resolution for the "timeline profiling"? Is it the same? 20ms?

Re: GPU Power Consumption

Hi,

The Application Timeline Trace profile session traces OpenCL and DirectCompute API calls and their respective GPU async invocations. These are presented on a timeline scale with a fine resolution of 1 microsecond.

The timeline of the Power Profiler has a minimal resolution of 20 milliseconds as you have noted.

I run latest CodeXL but I dont undestand the error message:
