With the acpi-cpufreq driver the CPU idles around 20W, frequencies are in t= he range of 2.2-2.8GHz. The very same system with the amd-pstate driver idles around 25W frequencies are in the range of 3.9-4.75GHz. This doesn't look right. Changing governor from ondemand to powersave reduces idle power consumption= to around 21.5W (still higher than with acpi-cpufreq) but this obvious complet= ely destroys performance. --=20 You may reply to this email to add a comment.
