Wearable devices are playing an important role in our daily lives. Nowadays, wearable devices have transformative implications for health, technology, connectivity, humancomputer interaction, and data analytics. Their importance lies in their ability to enhance various aspects of life and contribute to the ongoing evolution of digital landscapes. At the heart of smartwatch design, the processor takes center stage, driving the majority of advancements in smartwatch technology. This paper presents an experimental comparative study of ARM 64-bit processors, analyzing their performance and impact on power consumption, CPU usage, and battery temperature. We evaluate the characteristics of four smartwatch processors: Snapdragon W5+, Snapdragon Wear4100, Exynos W920, and Exynos W930. All of those smartwatches are equipped with ARM 64-bit processors. Our results indicate that none of the four selected smartwatches excelled in all aspects; each exhibits superiority over the others in specific features while being surpassed by others in different attributes.

Mobile devices are playing an important role in our daily lives. 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 devices, 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 results reveal that none of the three-selected smartphones was the best in all characteristics; each has superiority amongst others in certain characteristics and is dominated by others in other characteristics.
