Super Pi

Meanwhile Super Pi even in its latest version has become pretty old. Never the less it is able to show scaling to the clock speed nicely.

wPrime

wPrime is based on a multithreaded algorithm to calculate the square root to up to 32 billion digits. Therefore it is possible to put 100 percent load on every core or thread and to see differences between architectures.
