Power profiling with real-world workloads: A case study with MobileMark 2012

Technology clients expect with the release of a new device model that the device is more powerful and more energy efficient than its predecessor. There are many profiling tools aimed at profiling the energy efficiency of different platforms in order to provide consumers fair comparison of the energy efficiency of available platforms. Since improving the power consumption of devices is no longer the sole duty of hardware manufacturers but it is also the responsibility of software developers, we present a case study in this paper where we power profile Windows® 8 and Windows® 7 on the same hardware configuration using MobileMark® 2012 in order to compare how their efficiency compare to one another. Based on our results, we were able to show that Windows® 8 is a step forward to a better energy efficient operating system when compared to its predecessor.
