Re: AMDuProfCLI timechart for power profile on AMD Ryzen 9 3900X doesn't work

Hi rajeebbarman,

Thanks for the information.

I am measuring the power consumption for encoding videos on different AMD platforms, such as 3900X, 3700X, 3750H and 3700U.

It would be good if you can enable counters for "socket0-socket-power" on 3900X and 3700X. At present i can only extract data for "socket0-package-power" on 3900X and 3700X.

What is the difference between "socket0-socket-power" (Avg. APU Power) and "socket0-package-power"? It will be nice to have more concrete description of the counters in the report.

Best Regards,

Hemraj

Hi Hemraj,

 Sorry for the late response. Ideally both should be same.

Package power is calculated from RAPL energy counters, however socket power was calculated from SMU provided interface. Both should result the same. However, we are moving towards RAPL based energy counters as those counter are validated. Going forward, we are trying to avoid SMU based counters.

in case of 3750H, we have currently both "socket0-socket-power" and "socket0-package-power" and we have observed a difference in the readings. We are trying to  see the issue in "socket0-socket-power". However, as mentioned, we will be mostly using RAPL based counters ("socket0-package-power") and so "socket0-socket-power" will be removed from the next release of AMDuProf.

Regards,
Rajeeb
