All tests were performed with the default settings of the motherboard. We used to set the C-states on maximum and we enabled EIST, however we leave those decisions to the manufacturer now.
Of course the performance and power consumption depend on the standard tuning. Motherboard manufacturers used to cheat a little by slightly increasing the bClk. We and other review sites did not like this at all and the various manufacturers have therefore changed their ways. The maximum deviation we were able to find is 0.5%. They also no longer cheat with the clock speed of the IGP.
In the graphs on the following pages the ATX-motherboards are represented by the blue bars, while the Micro-ATX-boards can be recognized by their green bars.
