Windows 10: Task Manager showing high cpu speed with little or no Cpu utilization

Several windows 10 devices are showing high cpu speeds with litte or no Cpu Utilization in Task Manager. All or most of the devices use Windows 10 Pro 20H2 with build number ending with .868. On the newest desktop, I had installed .870 build. I tried removing .870 and .868 builds and still same result. Also, I tried changing the minimum processor usage to 100% and the cpu will show little cpu utilization in Task Manager. Any suggestions?

task manager displays wrong cpu speed/utilization



as can be seen, windows 10's task manager reports cpu speed as 3.26, where it is actually 4.13.

similarly, a multiplier of 28 will show a maximum cpu utilization of 80%.

the computer is running prime95, so it is definitely 100% loaded; this can be seen in various applications (e.g. intel extreme tuning utility, and many many others)

possibly the 125 bus speed is ignored? task manager seems to assume it is set to 100 in its calculations

is there a fix for this?

 

task manager displays wrong cpu speed/utilization

Hi Jimmy,

Thank you for posting your query in Microsoft Community.

I understand your concern and will be glad to help you.

Task Manager displays the programs, processes, and services that are currently running on your computer.

On the CPU section of the Performance tab, the actual CPU is now specifically identified in detail with the brand, the model number, the speed, as well as the number of sockets, cores, and logical processors.

Other third party performance monitor specifies the utilization and speed of the processor using different algorithms which differs from Windows Task Manager computations.

In addition, different algorithms are used to measure performance. For example, the algorithm used by Intel in its branded maximum speed is different than the algorithm used by Windows Task Manager to directly measure the speed of the CPU. You can use other
processor utilities, such as the Intel Processor Identification Utility or CPU-Z, for additional processor speed measurements.

Keep us posted if you face any issues on Windows in future. We will be glad to help you.

Thank you.

 

How to read the CPU utilization values shown in Task Manager

Hi all,

I am trying to monitor the overall CPU utilization and show it in my application(built using LabVIEW). Most of the online search suggests using performance monitor counters but the values are way off (sometimes 30% difference) from what is displayed in Task
Manager.

I would like to understand how the Task manager computes CPU usage and is there any DLL or Command line to get that value.

Thanks,

Mani.
