Performance Mode is already available for some desktop devices. I am not sure yet why not all of them have it 🤔
Anyway good suggestions

ok, maybe it's because in a notebook , only 2 configuration options is poor , when there is the possibility of minimum having four, without managing the turbo boost, the frequency range is 0.4GHz - 2.4GHz and with 4.2GHz turbo. In balanced works in 2.7GHz at 3.9Ghz and about 60 C - 85 C , with little demand for work.
I tried Ubuntu on the same computer, it has 3 configuration options and it works very fine in balanced

With the power profile selection in the control center, currently only 2 options "powersave" and "balanced".
When I selected "powersave" the CPU usage was very high, very slow with low frequency and low cpu temperature and little fan use and when I switched to "balanced" it increased the frequency a lot and very high the temperature and a lot of fan use with minimal processes.
I found a solution on the web, which works fine for me, and I share it and it would be good that in the next updates, in the energy profile, more profiles can be selected, such as
Power save
Conservative
Balanced
Performance
My solution ,Use with care, at your risk
All in terminal
for supported profile
$ grep . /sys/devices/system/cpu/cpufreq/policy*/energy_performance*
and then make according to the desired energy profile
"POWERSAVE"
$ echo powersave | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
$ echo power | sudo tee /sys/devices/system/cpu/cpufreq/policy*/energy_performance_preference
$ grep . /sys/devices/system/cpu/cpufreq/policy*/energy_performance_preference
"CONSERVATIVE"
$ echo powersave | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
$ echo balance_power | sudo tee /sys/devices/system/cpu/cpufreq/policy*/energy_performance_preference
$ grep . /sys/devices/system/cpu/cpufreq/policy*/energy_performance_preference
"ONDEMAND"
$ echo powersave | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
$ echo balance_performance | sudo tee /sys/devices/system/cpu/cpufreq/policy*/energy_performance_preference
$ grep . /sys/devices/system/cpu/cpufreq/policy*/energy_performance_preference
"PERFORMANCE"
$ echo powersave | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
$ echo performance | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
$ echo performance | sudo tee /sys/devices/system/cpu/cpufreq/policy*/energy_performance_preference
$ grep . /sys/devices/system/cpu/cpufreq/policy*/energy_performance_preference
and finally an executable file at startup
#!/bin/sh
echo powersave | sudo tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor
echo balance_performance | sudo tee /sys/devices/system/cpu/cpufreq/policy*/energy_performance_preference
