CPU利用率和能耗之间的关系是什么？ [英] What is the relation between CPU utilization and energy consumption?

问题描述

描述CPU利用率和能量消耗（电/热）之间关系的函数是什么。

我想知道它是线性的还是亚线性的/ exp等。

我正在编写一个程序，该程序可以降低其他程序的CPU使用率/负载，而我主要关心的是我从能源上受益多少。 p>

此外，我的服务器主要用作数据中心（无头）中的Web服务器或DB。

如果数据中心需要更多的电源来散热，我也需要考虑这一点。
我还需要知道CPU利用率对整个机器功耗的影响。.

HTH！

What is the function that describes the relation between CPU utilization and consumption of energy (electricity/heat wise).

I wonder if it's linear/sub-linear/exp etc..

I am writing a program that decreases the CPU utilization/load of other programs and my main concern is how much do I benefit energy wise..

Moreover, my server is mostly being used as a web-server or DB in a data-center (headless).

In case the data center need more power for cooling I need to consider that as well.. I also need to know what is the effect of CPU utilization on the entire machine power consumption ..

Here you can find a short ppt answering your questions, and providing additional info.

Although there is no Copyright notice in the ppt, the work is probably protected, so I will copy here only three graphs relevant to your main question and follow-ups in comments.
