Or maybe you're ready to replace your hard drive with a faster SSD model.

My article FREE Tools to Tune and Optimize Your Hard Drive.

Keeping your hard drive in optimal shape can help to improve overall system performance. But SuperPi won't tell you anything about the performance of other parts of your computer system. Overclockers consider SuperPi a favorite free benchmark because it is processor-specific and helps them see how successful they are at getting their CPUs to run at faster than rated top clock speeds. SuperPi tracks how quickly your processor performs the operation. It calculates pi to over 4.2 billion decimal places, a very processor-intensive task. SuperPi is a free benchmark test program designed to measure the speed of your CPU. Benchmarking is an objective way to see how much, or how little, your computer's performance changes over time. Benchmarking is simply a matter of measuring the performance of your system before you start tweaking it, so you have a set of numbers to which you can compare post-tweak measurements. When you try one of the many tricks to speed up your computer, how do you know whether or not it actually worked? A psychological phenomenon called "confirmation bias" makes your gut feeling about the effect of a tweak (or an expenditure) unreliable after all the work (or money) you put into speeding up your computer, you want to confirm that it worked as hoped.įortunately, we have tools to measure system performance more accurately than "Yeah, it seems a bit faster now." That's where free performance benchmarking software comes in. Or perhaps you're one who likes to tinker or overclock your CPU. And then there's the problem of comparing Intel versus AMD, and one brand versus another, when they use differing units of measurement. But after comparing CPU clock speeds, graphics adapter frame rates, motherboard bus capacity, hard drive data transfer, RAM speeds, and other arcane stats, your head starts to spin.

It's true, computer vendors like to throw around numbers to dazzle you, when describing how fast their systems are.
