The usage of laptops and cell phones has drastically increased recently, specifically because of the Covid-19 pandemic. The pandemic and resulting shut downs have necessitated online studies, work from home, online meetings, video conferencing etc. Availability of either a laptop or cell phone has become basic requirement for attending online classes or virtual meetings. Hence, the usage of entry-level laptops (for example Intel Core-i3) and mid-range laptops (for example AMD Ryzen 5) has recently gained popularity. This particular research study aims to determine the power consumption and changes in temperature of the microprocessor, physical memory, and integrated graphics card when different benchmark software (Cinebench R23, Unigine Superposition 1.1), stress test, and video game (CS-GO) executing instructions individually and simultaneously with each other. Three different types of system configurations (Intel Core-i3, AMD Ryzen 5 low power, and AMD Ryzen 5 High-performance) were used to determine the performance and benchmarking of the processor with different physical memory, and different integrated graphics processing units. These processors have been tested under multiple benchmark software, stress tests, and video games. Cinebench R23, Unigine Superposition, Counter-Strike: Global Offensive software/game were used to analyze the performance. Mainly, power consumption, temperature changes with the different load on the processor, physical memory, and load on integrated GPU were analyzed when application was running. © 2021 ACM.
