Have you ever wanted a good comparative method to test the actual speed of your CPU? You can measure its physical speed in GHz, but it won't give you much idea as to how fast it can actually solve problems. For example, you can clock a Pentium 4 at 4GHz, but an i7 at 1GHz will probably be still a lot faster. There are various other benchmarks, like CPU Marks
, ok for comparing your CPU to others, but they are otherwise meaningless, and require payware to test your own configuration. If you want to benchmark you CPU, it is best to use GFLOPS (Giga [Billion] FLoating-point Operations per Seconds). It is what all supercomputers will use to test their speed and a very good measure of the processors true speed.
NOTE: This only works on Intel CPUs. You can probably find one for AMD if you google it, but as I don't have any, haven't really looked. Only thing I could find was a linux version you have to compile yourself.
