Now the cpu can execute an instruction at each clock cycle (this is an over-simplification but bear for now). The answer lies in how the usage is measured.Ī cpu has a clock that runs at a certain speed, for example 1000 hz which means there are 1000 clock cycles each second. Then how do we get these usage indicators in the form of a percentage number like 35% or 95%. In this article we shall be discussing about 4 key cpu metrics which are:Īt any given moment, a cpu core is technically either executing an instruction (100% usage) or not executing any instruction (0%). The metrics can be monitored using tools like Hwinfo, Open hardware monitor, core temp etc on windows. ![]() ![]() There are many more but for simplicity we shall be focusing on these ones in this article.
