Test System Setup
With the new GTX 400 series being released we thought it was time to drop the GTX 285 for a more updated card. But since the GTX 400 series is quite limited we thought we would stick to the old faithful Radeon line and have chosen to now use the Sapphire HD 5870 1GB.
Since we've got a new video card in, we've got to start again when it comes to benchmarks, so today we'll only be comparing the Kingmax in its overclocked form and stock form. We've also added the TPR and TVR graphs which you may've seen in our recent video card reviews.
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.
You can see that when we crank up the MHz the performance of the modules really shines thanks to the extra MHz on both the core and memory.
