So base power limit should be 65w not 55w. The video card never reach 90w limits => less performance potential
I also noticed strange behavior that when /sys/devices/system/cpu/cpufreq/boost is 1, then nvidia can use only 60w power, so sometimes performance without cpu frequency boost is better than while it turned on.
On Windows didn’t see the problems
