ELI5: Explain Like I'm 5

Benchmarking

Benchmarking is like a race. In a race, all the runners compete to see who can run the fastest. In benchmarking, you compare your computer or phone to others to see how fast and powerful it is. You might compare your computer to one twice as powerful, or compare your phone to one with a newer processor. Benchmarking helps you decide if it’s time to upgrade, or if you're better off waiting.
