wPrime is a leading multithreaded benchmark for x86 processors that tests your processor performance by calculating square roots with a recursive call of Newton’s method for estimating functions, with f(x)=x2-k, where k is the number we’re sqrting, until Sgn(f(x)/f'(x)) does not equal that of the previous iteration, starting with an estimation of k/2. It then uses an iterative calling of the estimation method a set amount of times to increase the accuracy of the results. It then confirms that n(k)2=k to ensure the calculation was correct. It repeats this for all numbers from 1 to the requested maximum.
Benchmark Results: When it comes to wPrime more cores is king. Despite the higher clock speed of the iBUYPOWER Paladin XLC Phantom with the Intel Core I7 930 overclocked to the iBLabs Level 3 overclock, the stock Intel Core I7 970 left the Intel I7 930 systems looking like they were standing still.
