Measure CPU Clock Frequency in Windows with CpuFrequenz

There are many things that can slow down your computer and hamper its performance. On the hardware side, good amount of RAM, faster hard disk drive or solid state drive, and a multi-core processor are needed for better performance of your computer. On the software side, you must not mess with the operating system settings in order to make it use the hardware at its peak performance.

If you are feeling like the processor of your computer is not working at its full performance even when you have good hardware, then it could be because operating system settings, BIOS settings, failure of thermal paste or build-up of dust. In some computers the BIOS prevents the CPU to reach peak clock frequency to avoid the heating of the CPU – this setting can be disabled from the BIOS/UEFI interface. CPU won’t give good performance when it is getting too hot because of heat-sink/thermal paste failure either.


In order to find out whether your CPU is running at lower clock frequencies, you can use CpuFrequenz freeware. It is portable tool and can show you the current clock frequency of your computer’s CPU. It works for all kinds of CPU and supports Windows from  Windows 98 to Windows 10.

In the user interface, it displays the CPU load in percentage, a graph displaying the load and CPU load in real-time and the current CPU clock frequency. It also has a precise clock frequency determination feature using which you can determine the maximum clock frequency of your CPU.

CpuFrequenz can tell you the exact precise clock frequency of your computer’s main processor. It can load all of the cores of your CPU and measure the real-time clock frequency so that you can get actual reading of the clock frequency as opposed to just reading the boiler plate of the processor.
