I have a i7 13650hx
The problem is that when im on windows and gaming the Cpu wattage always be 100+ watts so it gives good performance
But on linux same game same setting the wattage is goes to 70 -80 watts for 8-10secs and then comes back to 55watts (the base wattage)
What could be the problem? Turbo boost is on it reaches 4.9ghz freq too

Hi tr1x_em,

Thank you for posting in the Community!

I've noticed that this is a laptop processor. I would like to clarify some things first.

Please note that this is an OEM device, so I will try to assist you with general troubleshooting steps. However, if the issue persists, you will have to contact the Original Equipment Manufacturer of your device. Your device manufacturer may have altered features, incorporated customizations, or made other changes to some components for better compatibility with your system.

When did you noticed this behavior?

Did you do recent changes with the system?

Have you performed other troubleshooting steps?

Have you updated the BIOS version to the latest?

Best regards,

Dean R.
