Nowadays, mobile devices are not only phones to call and text, but they are also smart devices that enable users to do almost any task that could be done on a regular PC. At the heart of the design of smartphones, there lies the processor to which almost all the development in the smartphone arena is attributed. Recently, ARM processors are among the most prominent processors used in mobile de- vices, smartphones, and embedded systems. This paper conducts an experimental comparative study of ARM 64-bit processors in terms of performance and their effect on power consumption, CPU temperature, and battery temperature. We use a number of well-known benchmarks to evaluate those characteristics of three smartphones, namely, Snapdragon 778G+, Exynos 1280 and HiSilicon Kirin 980. Those smartphones are all equipped with ARM 64-bit processors. Our re- sults reveal that none of the three-selected smartphones was the best in all char- acteristics; each has superiority amongst others in certain characteristics and is dominated by others in other characteristics. Keywords—ARM 64-bit, mobile processors, smartphones, RISC, SoC. 1 Introduction Mobile devices and IoT are ubiquitously playing an important role in our daily lives [1, 2, 3]. In the recent years, mobile devices are increasingly spreading between chil- dren, adults, and elders [4, 5, 6]. The widespread of smartphones and their applications [7] paved the way to new technologies to rise in order to support the new trends in computation, infrastructure, and storage, such as distributed systems [8], fog computing [9], and cloud computing which became ubiquitous and inseparable from smartphones [10, 11]. The Advanced RISC Machine (ARM) is a microprocessor technology, as well as a family of processors based on the Reduced Instruction Set Computers (RISC) architec- ture. This kind of processors is used heavily in smart systems and electronic devices due to the prevailing features it comprises, such as, (1) high performance, (2) low cost, and (3) low power consumption [12, 13]. 94 https://www.i-jim.org
