Benchmarking gives you a well-defined overview of the internals on your PC. It’s quite important to know everything about your PC: hard drive performance, RAM size, processor speed, GPU performance, etc. Whether you’re overclocking your computer or comparing it to another computer, benchmarking can help you translate your computer’s performance into numbers. There is a wide array of benchmarking applications for the Windows ecosystem of which most are free.
