Abstract

Reducing CPU frequency and voltage is a well-known approach to improve energy consumption of memory-bound applications. This is based on the conception that the performance of the main memory sees little or no degradation at reduced processor clock speeds, while power consumption decreases significantly and the overall energy efficiency improves. We study this effect on the Haswell generation of Intel Xeon processors as well as the ARMv7 generation of the 32-bit ARM big.LITTLE architecture. The goal is to analyze and compare performance, energy consumption and resulting energy efficiency on a series of tasks, each focusing on different parts of the system, provide analysis and generalization to other similar architectures. The benchmark suit consists of compute and memory intensive benchmarks as well as both single and multi-threaded scientific applications. The results show that frequency and voltage scaling can significantly improve algorithms' energy efficiency, up to 2.5x on ARM and 1.5x on Intel compared to the maximum frequency. ARM is up to 2x more efficient than Intel. The results are valuable for scientists in the areas of computer architecture, performance and power analysis as well as application developers seeking to optimize their Haswell x86_64 and ARMv7 hardware setup to improve energy efficiency.
