Arch Kernel not able to utilize the maximum clock speed

It was yesterday i was monitoring my clock speeds with Arch Kernel booted and found that its actually half (1.8 ghz) of my burst clock which is 3.4 ghz. But when i install Zen kernel i can reach 3.4 ghz in performance governor. Why is that so?
I have an Intel 8th gen 8250U cpu

Re: Arch Kernel not able to utilize the maximum clock speed

Were you comparing the performance governor on both kernels?

Re: Arch Kernel not able to utilize the maximum clock speed

How do you know that the `linux` kernel doesn't?

How have you configured your laptop? Are you running on battery? etc.

Which specific kernel i.e. stable, hardened or longterm ( https://wiki.archlinux.org/index.php/Kernel ) and which specific version?
See also https://bbs.archlinux.org/viewtopic.php?pid=1966032

Also for "burst clock" do you mean "Max Turbo Frequency"?
Also what does the

i7z

https://archlinux.org/packages/community/x86_64/i7z/
command tell you?

I have enabled Intel turbo boost in my BIOS.
And i never run it on battery
