Really low CPU (12900H) performance in linux (Manjaro)

[Mnky313]

I've been messing around with linux on the Flow Z13 but I can't get the CPU to run at anywhere near full speed.

even when running stress (with 20 threads) the CPU reports 100% usage but only pulls ~15W and sits at ~1GHz...

turbostat shows a max PL1 of 60W and PL2 of 115W: (I attached the output from turbostat (specifically turbostat --Summary --interval 5 --show Avg_MHz,Busy%,Bzy_MHz,IRQ,PkgTmp,PkgWatt,GFXWatt)

cpu0: PKG Limit #1: ENabled (60.000000 Watts, 56.000000 sec, clamp ENabled)
cpu0: PKG Limit #2: ENabled (115.000000 Watts, 0.002441* sec, clamp DISabled)

I've tried selecting both balanced and performance from the menu in manjaro but it seems to make no difference.

Maybe the manufacturer set the power limit to 15W,

What is the make and model of the laptop?

It's an Asus ROG Flow Z13, It shouldn't be that low. 

In windows the power limit seems to be 95W/45W without anything changing it but can be increased with throttlestop.

What is the output of

 

sudo cpupower frequency-info

 

Edit - You might need to do

 

sudo pacman -S cpupower

 

before running the first command.

(I also tried setting the governor to performance and it made no difference)

OK, that looks pretty normal (though I cannot say if that is true for 12000s since I don't have access to one).

 

Try running

 

sudo systemctl disable --now tlp

 

and then rerun your CPU test and check if anything changes. I suspect its a software issue, maybe TLP isn't correctly configured for 12000s or maybe it just doesn't like them.

tlp doesn't exist for me, the output of that command is:

Failed to disable unit: Unit file tlp.service does not exist.
