GPU computing is something which is fast becoming a very important feature on "video" cards. NVIDIA have a number of useful utilities for CUDA enabled cards which all help to enhance the performance of day to day tasks. On the AMD front we have "Stream" applications which use the GPY to enhance performance. Here we have taken a few examples of the different technologies at work to find out how the cards benefit us in real world use.

GPU Assisted Media Conversion
When looking at the Windows Drag and Drop Transfer results there are very clear advantages to be seen from using our GPU to assist the CPU. In the case of our media conversion test the results look less impressive but what they don’t show is that the GPU assisted results were achieved with less CPU use. The HIS 6970 freed up around 8% (on average) of CPU performance for other tasks while the encoding was taking place.
