Since this is our first AMD rig in a long time, we don't have any other kits on the same system to compare this one against. Instead, we've included some results from our P55 and X58 testbeds using Intel processors. We know that memory performance on the Intel platform is better, but let's see how they compare anyway. We also want to see what kind of performance increase we get as we climb up in speed.
Let's get started!
Important Note: When modules are overclocked we adjust the BCLK which not only lets us fine tune the MHz out of a module, but in turn increases the overall CPU clock speed. While we always make the effort to include the BCLK and CPU Speed in our graphs, please just make sure that you make note of these when looking at the results. In some tests that don't purely test the memory speed the extra MHz on offer from the CPU can increase the result. Of course, it's worth noting that having faster memory gives you the ability to run your CPU at a higher speed.
wPrime uses 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're a long way away from our Intel setups, but you can see that as we increase the speed of our CPU there is a nice little performance improvement.
