Mobile Processor Energy Usage in the Scientific Environment

The processor industry has been facing challenges for several years. This is due to both technical challenges and changing market conditions. The outcome of these challenges was energy-efficient, multicore processors. This article examines the energy efficiency of several generations of Intel and ARM processors and investigates how architectural changes influenced power consumption. We were able to compare the Intel and ARM processors on an equal footing and could place our work in the context of previous work done in this regard, especially on Intel processors. We found that while the static energy consumption trended downwards, architectural changes in especially the mobile processors resulted in increased dynamic energy use. We also observed that their dynamic energy usage was less favorable even though the ARM processors at idle consumed a fraction of the energy of the Intel processors.
