Asus X99 Deluxe Redux, Battle Of the BIOS!

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.




The Asus X99 Deluxe showed sparse improvement from BIOS 0505 to BIOS 1401 so even 8 BIOS generations later they pretty much had it right from the beginning.


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.




When we hit the Wprime test it was obvious the improvement from BIOS 0505 to 1401 was enough that you can attribute it to the BIOS revision improvements. We wouldn’t expect less from Asus as they pay close attention to their end users and stay on top BIOS revisions with an Eagle eye. Having that fast accurate attention to BIOS improvements is one of the Reasons Asus is a world leader in motherboard sales.
