Post Description

wPrime is a leading multi-threaded 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.
