In this paper we present a detailed energy consumption analysis, considering the consumption components of CPU, cache memories and main memory, for all ×265 presets executing in a multicore system. Ten HD 1080p test video sequences with different motion and brightness characteristics are used in the experiments. Three tools are used to obtain the results: CACTI, PCM and Perf. To get more reliable time/energy results, 10 executions were performed for each preset. The results show that fast presets are 47× faster than slower presets. However, slower presets use robust configurations and achieve large reductions in bitrate. Due to this, the ultrafast preset has a bitrate 45% higher than placebo preset. Furthermore, the system energy consumption increases 45×, from ultrafast preset to placebo preset. Our experiments clearly present the dependence between bitrate and energy consumption for all encoding presets, which allows us to choose the best bitrate/energy trade-off for each platform at hand.","keywords":"energy consumption;high definition video;image sequences;power aware computing;video coding;ultrafast preset;placebo preset;system energy consumption analysis;HEVC encoders;CPU consumption components;X265 presets;CACTI;PCM;Perf;brightness characteristics;HD 1080p test video sequences;multicore system;main memory;cache memories;X265 video encoder;bitrate/energy trade-off;encoding presets;Energy consumption;Tools;Encoding;Bit rate;Cache memory;Phase change materials;Software;Video encoding;HEVC;x265;energy consumption;multicore system","doi":"10.23919/EUSIPCO.2017.8081463","issn":"2076-1465","month":"Aug","url":"https://www.eurasip.org/proceedings/eusipco/eusipco2017/papers/1570347537.pdf","bibtex":"@InProceedings{8081463,\n author = {D.
