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 950 was able to knock off nearly 25 seconds from the time it took the Intel Core I7 930. That is an 8.2% performance boost! Though the leader of the day is the Intel Core I7 970 which was 73 seconds faster than the Intel Core I7 950 and three to four times the price.
