Power Consumption Tests
To complete our article we decided to also measure the power consumption of Intel Skulltrail platform (without the monitor) and compare it against that of a Core 2 Extreme QX9770 based platform. Both systems were configured the same way as during performance tests. The CPUs were loaded with Prime95 25.5 utility.
Although new Intel processors become more and more economical, it seems to be not the case for Skulltrail. There are three factors determining high power consumption in idle mode. Firstly, there are two processors inside. Secondly, this system is equipped with FB-DIMM DDR2 memory that is not economical at all. And thirdly, Skulltrail platform doesn’t support Enhanced Intel SpeedStep technology.
Under heavy workload Skulltrail platform consumes about 400W of power, which is a sort of a record for contemporary desktop systems. Here we should point out that Core 2 Extreme QX9775 processors consume evidently less than 150W TDP. Namely, the difference between the platform with one and two processors is only about 80W.
