Benchmarking
Benchmarking is running a set test on a computer to measure how fast it performs.
A baker times how long it takes to fill a tray of 12 muffin cups with batter. She uses the same tray, the same batter, and the same tool each time. The time on the clock shows how fast she worked that day. Comparing today's time to last week's tells her if she got faster or slower.
Explaining benchmarking by grade level
Think about timing how fast a computer opens a game. You run the same task each time. Then you change one part, like the brain of the computer. The time it takes tells you which part made it faster or slower.
Projects that explore benchmarking
Benchmarking means running a set test on a computer to measure how fast it performs. In this experiment, you run the same speed test after changing one part at a time — the CPU clock speed, the backside cache, or a software extension. Because the test stays the same each time, the scores show exactly which change made the computer faster or slower.
A benchmark becomes especially useful when comparing hardware upgrades under realistic conditions. You time how long each CPU-and-RAM combination takes to start up the computer and load a game — first alone, then with five other programs running in the background. Running the same set test across all four hardware setups produces direct, comparable measurements of everyday performance.
