CPU :  11th Gen Intel(R) Core(TM) i5-1155G7 @ 2.50GHz

OS : Ubuntu 20.04.5 LTS

kernel : 5.15.0-58-generic

 

I want to know one core's consumption in every frequency point.

How can I get them ?

Hi Albert,

Thanks for your reply.

 

I am going to make a program to display each APP's power consumption.

I think the consumption = time @ freq * power @freq .

So I need the exact value for compute the consumption.

Hello Kongrong, I just received an update on this matter.

 

After reviewing the case, it is essential to mention, that each application's power consumption is different or constantly changing based on the application load, system status, hardware configuration, etc. The processor power consumption is also always changing based on the Operating System configuration, application load, etc, so those values will always be different as well.

Hello Alberto,

I read the Linux source and found that the frequency of a cpu is not export to us, because of the frequency is adjusted by hareware. So I can not know when the frequency is changed。

I think I have to find other way to get the power assumption.

Thanks.

Hello Kongrong, Thank you very much for your response.

 

Correct, since each application's power consumption is different and always changing, as an alternative, you can get in contact with the application developer to try to gather further details on this topic.

 

And since the processor's power consumption is also always changing based on the Operating System configuration as well, if you are using Linux, you have the option to get in contact directly with Linux Support to gather additional information on this matter:
