Here is my system info:
Operating System: Arch Linux
KDE Plasma Version: 5.23.5
KDE Frameworks Version: 5.89.0
Qt Version: 5.15.2
Kernel Version: 5.15.13-arch1-1 (64-bit)
Graphics Platform: X11
Processors: 8 × 11th Gen Intel® Core™ i5-1135G7 @ 2.40GHz
Memory: 15.4 GiB of RAM
Graphics Processor: Mesa Intel® Xe Graphics
There are some cores that can run up to 4.2GHz when the system is idle, but at full load all core frequencies drop to about 1.2GHz. I tested it on Windows, and the full load frequency can be stable at around 2.5GHz (of course, the laptop doesn't get very hot in Linux.).
I don't know what to do, is there any way to keep the core frequency higher in ArchLinux?

https://wiki.archlinux.org/title/CPU_frequency_scaling (likely performance governor) but before doing any of this see https://wiki.archlinux.org/title/Microcode

I just updated the microcode and I'm using intel_pstate, but the frequency limit still seems to be there (about 1.6GHz at full load).

Do you also patch the microcode (early)?
Also check the conditions in /sys/devices/system/cpu/intel_pstate/ (notably turboboost and governor)

For me installing thermald unlocked full capacity of the cores

Thanks, this solved my problem.
In hindsight, my laptop fans wouldn't fully work at first, which was actually because the cooling system wasn't properly driven. And thermald can solve this problem. Here is what I do:
sudo pacman -S thermald
sudo systemctl enable thermald
sudo systemctl start thermald
