Dear Lesswatts folks,
issue 3/2012 of the German Linux Magazin looked at the energy consumption of different GNU/Linux distributions. A Fujitsu Lifebook e751 vPro with an Intel Core i7-2620M and Intel graphics is used. As I read the result OpenSUSE 12.1(?) with `kernel-default` and GNOME has the lowest value of 11,4 Watts shown in PowerTOP. Using their benchmark to simulate user input the distributions compare as follows. Ubuntu (Unity) 3:04 hours Mint (GNOME) 3:14 hours openSUSE (KDE) 3:23 hours Mint (LXDE) 3:25 hours Windows 7 Professional 4:05 hours As far as I could see they enable our power saving features like RC6 for the Intel graphics hardware. Additionally they also write that although tuning a lot of setting and PowerTOP also showing that less Watts are consumed that this did not have a big effect on the runtime. Is there something wrong with this setup? Additionally are there obvious explanations why Windows still runs that much longer?
