5. The exact CPU frequency is displayed after the measurement (point 4)
The maximum CPU frequency achieved by the individual processors / threads then results from the peak value. You can repeat the CPU frequency measurement at any time regardless of whether you are measuring the CPU frequency on a Microsoft Windows desktop system (10, 8.1, ...) or on an MS Server Server 2019, 2016, ...! The CPU frequency measurement can be determined at any time and again and again!
(Image-1) Example of the exact CPU frequency query on MS Windows 10 OS!
2.) Technical information for determining the CPU frequency!
When calculating, the clock rate, also known typically as the CPU frequency, with which the clock generator of a processor works, this is also used to synchronize the operations on the PC.
So it is the indicator for the speed of the processor, this is also given in cycles per second as a unit, also known as Hertz!
A CPU with a clock frequency of 3.0 GHz executes 3.0 billion cycles per second, but several operations can be carried out per cycle. For example, with a modern CPU, two additions can be made per clock, with a 4 core CPU with 3 gigahertz you get 4 x 3 x 2, to 24 billion additions per second!
3.) What should I watch out for when querying the CPU frequency?
The CPU frequency can also deviate, for example modern CPUs have the ability to reduce the clock rate if there is a threat of overheating, which leads to a different result of the measurement.
It is the same with mobile devices, tablets, MS Surface, laptops, ... these can also reduce the maximum CPU frequency in battery operation in order to save the battery and thus achieve a longer runtime in battery operation!
From version 2.11 a better recognition of some CPUs and the manufacturer as well as series is available above all with Intel processors This screenshot
It is quite easy to solve the problems with the installation of the CPU query tool for MS Windows 11, 10, , whether on desktop or server operating systems
If the CPU frequency is not always the same, it can have different causes, it does not have to be a faulty / defective CPU The processor / CPU frequency
After the various update to eg 1607 the processor does not seem to be down-clocking anymore. For notebook and Surface Pro or GO it is partly connected to
