Tashkinov (aros@gmx.com) --- The conservative governor idles around 21W which is good but this governor = is very undesirable for a desktop system: it's too slow to react to instantane= ous spikes in workload and it makes e.g. web browsing far from comfortable. So, with amd-pstate in idle: Powersave and performance (!) governors ~ 20W. Conservative ~ 21W. Ondemand ~ 23.5W. --=20 You may reply to this email to add a comment.
