ASRock Fatal1ty X99X Killer, The Thriller With The Killer

SuperPi Mod 1.5 & WPrime

SuperPI Mod 1.5

Super PI is a single threaded benchmark that calculates pi to a specific number of digits. It uses the Gauss-Legendre algorithm and is a Windows port of a program used by Yasumasa Kanada in 1995 to compute pi to 232 digits.



SuperPi is a benchmark that the winner in any bunch is usually determined by fractions of a second. The Asus Rampage V beat the ASRock Fatal1ty X999X Killer by 0.15 seconds on the 8M test and less than that on the 1M test. While a win is a win how much of a win is it when the winning board cost 2x as much as the second place board?


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.




The ASRock Fatal1ty X99X Killer came in third here and ran a fraction of a second behind the Asus X99 Deluxe and about 3 seconds behind the Asus Rampage V Extreme.
