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 GPU 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 Radeon does drop the encoding time a little, CPU use too, however the clear winner is the GTX 590 which finishes 12 seconds faster. Not only that though the quality of output provided by Badaboom is far in excess of the AMD solution.
