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.
We had to go into the wPrime settings and set the thread count to eight in order for the Intel Core i7-2820QM processor to run at 100% load across all available threads.
Benchmark Results: The Intel Core i7-2820QM processor tears up the competition in wPrime v2.04 and completed a 32M run in just under nine seconds!
