Asus Z9 PE-D8 WS / Dual Xeon E5 2687W / 64GB Kingston DDR3 Review

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 set wPrime to 32 cores.

A final time of under a minute is incredible and shows the power on hand when using two 2687W processors. The overclocked Core i7 3960X EE @ 4.8ghz managed to complete the test in 120 seconds.
