1800MHz is a bit of a weird number for our dividers. With a 200MHz BCLK our dividers only give us the option to run at 1600MHz or 1800MHz. What this meant is that we had to move around the BCLK a little, so while we normally have a 200 x 20 setup, the GeIL modules at 1800MHz are using a 180 x 16 setup which results in a 3.6GHz clock versus the normal 4GHz clock we're use to seeing.


This is worth noting and the setup can be seen in our graphs on the following pages. While the clock will have an effect on benchmarks that rely more heavily on the CPU, when it comes to pure memory benchmarks the clock speed should have little to no impact.

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.

With wPrime mainly taking advantage of the CPU, we can see that the GeIL kit falls to the back of the pack here.
