wPrime
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: The Intel Core i7 990X Extreme is significantly faster in wPrime than anything else we have tested. Running the 1024 Million benchmark the 990X completed those calculations in an average of 165.49 seconds. That is 61.627 seconds or 27.1% faster than the Intel Core i7 2600K. Calculating 32 million the 990X was 1.886 seconds or 24.7% faster than the 2600K!
