CPU-Z, for example, is a lightweight program that displays detailed information about your CPU, such as its model, speed, voltage, cores, cache, and features. Prime95 is a powerful program that puts your CPU under extreme stress to test its stability and performance. FurMark is an intensive program that tests your GPU's performance and stability. UserBenchmark is a simple program that tests your CPU, GPU, RAM, SSD or HDD, and USB drives. Lastly, CrystalDiskMark is a comprehensive program that tests your SSD or HDD's performance. These tools can help you check if your hardware is running optimally and if it supports the latest technologies as well as monitor temperatures, power consumption, fan speeds, read/write speeds and access times. Additionally, you can use UserBenchmark to compare your hardware's performance with other users' systems and get recommendations on how to improve it.
