Clock speed in task manager

[Stonelg441]

Clock speed going down/showing to 4.7ghz from 5.2 in stress test/100% CPU load, while in other benchmark tool showing proper clock speed which is 5.3 to 5.2

Specs: i5 14600k

            MSI   B760 tom ddr5 wifi 

            16 2 ddr5 ram 6000mhz

Well, the question is, which speed is the task manager showing? average? P-cores? E-cores? something else?

I would not use task manager to monitor frequency. 

[Stonelg441]

All overall core speeds are shown in the task manager CPU section, why is the task manager CPU clock showing less CPU clock while any other third party shows the correct CPU clock which is 5.3ghz of i5 14600k?

[KrissyG]

So which core frequency is the correct one?

See what i did there? 
An app or task manager, which shows only one frequency, can either show max or average. There is no correct value, it's either average or max. And task manager has a slight delay when showing the speed.

This 'math' works for me very well bcoz i have 8P and 8E cores, and average on 8P cores was close to 4,9 and average on 8E cores was close to 3,6.

which processor are you using?

mine is an intel core i5 14600k turbo boost speed should be 5.3ghz as the HW monitor shows

if your PC i7 4th gen your turbo boost should be 5.6ghz.

and last, why are you doing average clock speed?

i rewatched your Video, and recalled that the task manager will show the average if CPU is actually under load, not sure what it's showing on idle.

The CPU i have is i7 13700k, it never hits the stock speed it supposed to have at 5,4GHz on two cores, never. Instead it does 5,3GHz on all Pcores. Of course i run it on a B760 motherboard which does not support overclocking, so that maybe connected to the speed it gives me.
Well, 2 cores at 0,1GHz more would change the performance by literally +0.0....%. It would just draw more power.


And if you run on High performance, your idle temperatures will be high, balanced is best, there may be sometimes a slight delay in perfomance, but barely noticable.

In ideal condition it hit 5.3ghz,

YES...You are correct about the power option 

thanks for clearing up my doubts, I was not aware of the average terms on 100%  load CPU in Task Manager.
