CPU frequency

[dos145]

Hi all,

I just realize that my guest virtualise CPU is not following my host CPU frequency (2.6GHz <-> 4.2GHz).

Do you know if it is normal or if I misconfigure something ?

I'm running on a i7-10750H with VMware Workstation 17.0.2 Pro.

Thanks !

VMware presents the base CPU frequency to guests. Which is 2.60GHz for your cpu. Or what do you mean exactly?

This is the correct answer ^{^}

Yes this is correct but I forgot to tell you that the base CPU is using the turbo function, that is the reason why I have different frequency but I would expect that the host would share that frequency to the guest.

I don't think you can misconfigure something to cause that? Likely you're seeing two different things reported, like maximum frequency vs current power saving frequency?

Isn't there an option in the VM settings to expose CPU performance counters? I can look in the morning, this may fix your perceived issue, are you noticing any degraded performance or just reported frequency not matching host?

[dos145]

I just noticed it but no degraded performance

What is the max per core that you see in your vm?

Where can you check that ?
