You might want to check what cpu power configuration is available in the bios firmware. Your IPC or motherboard manual should have instructions how to get into that, during boot, before grub starts.
A lot of 'compact' PCs provide a method of setting high performance vs quiet or energy saving. I'm of the opinion linux generally obeys that hardware setting but windows sometimes has ways of overriding it and using max power anyway. This can give the illusion of windows performing better than linux.
If that's not it then I might investigate whether there is some missing firmware. A starting point might be
sudo dmesg | grep -Ei 'fail|error' to see whether anything jumps out.
