Want to share my benchmark result with Geekbench 5, this is with limiting the turbo power and normal power to 16W and 8W using voltage-shift.
Below is metal score
It seems the performance impact is minimal (about 100 points lower for multi-core but I've got higher single-core) when comparing to below result:
And if I compare with other benchmark:
My result seems to be inline with the other i5.
My MBA is silent during the benchmark I couldn't even hear the fan, so using voltageshift to reduce the heat seems to be successful for me.
I've attached the voltageshift I use.
Below are the steps to set it up:
1. Extract the content of the zip into a folder (e.g. ~/voltageshift)
2. Go the extract folder and execute below command:
Code:
sudo chown -R root:wheel VoltageShift.kext
3. Boot your into Recovery (CMD + R)
4. Once in recovery, select the Terminal at the toolbar
5. Enter following command in the terminal:
Code:
csrutil enable --without kext
6. Reboot by executing below command in the Terminal:
7. Once you're back to Catalina and log-in, go to the voltageshift folder and execute the command:
You will be asked to provide password as it need to run as root / admin.
If all well you should see the information like below:
And will be able to see the power information at the end:
8. Now you can execute the shift.sh which will setup the power to 16W - 8W
You might be asked to enter the password again.
9. After executing the shift.sh you can check the setting by running the ./voltageshift info and should see:
The setting won't persist after a restart, so you'll need to execute shift.sh again after a restart.
For myself I've setup a plist file which will load the setup every time my system load hence I don't have to execute the script manually after a restart.
You can watch the video below to know what's going on:
The video will shows you how to setup voltageshift very similar to the steps I gave.
