HyperPi is a front end for SuperPi that allows for multiple concurrent instances of SuperPi to be run on each core recognized by the system. It is very dependent on CPU to memory to HDD speed. The faster these components, the faster it is able to figure out the number Pi to the selected length.
For our testing we use the 32M run. This means that each of the four physical and four logical cores for the i7 and the four physical cores of the i5 is trying to calculate the number Pi out to 32 million decimal places. Each "run" is a comparative to ensure accuracy and any stability or performance issues in the loop mentioned above will cause errors in calculation.
We again see at stock there's little difference between the setups; it's a little faster, but nothing major. When we crank up our clock speed, though, we can see that we gain a lot more speed and the Maximus IV Extreme offers us the highest performance.
AutoGK stands for Auto Gordian Knot; it is a suite of transcoding tools that are compiled into an easy to install and use utility. It allows you to transcode non-protected DVDs and other media to Xvid or Divx format. For our testing purposes we use a non-DRM restricted movie that is roughly 2 hours in length. This is transcoded to a single Xvid AVI at 100% quality.
At stock our ASUS Maximus IV Extreme is a little faster which is nice. When overclocked we can see the big improvement that is offered and we really manage to shave a big chunk of time when it comes to our encoding speed.
