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. 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.
Windows Drag and Drop Transfer
Our test file is a 42 minute AVI file.
GPU Assisted Media Conversion
Our test file is a 640×480 resolution file of approximately 90MB which we run through the 1click-fix filters while increasing the resolution to 720p.
When looking at the Windows Drag and Drop Transfer and vReveal 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 CUDA results were achieved with less CPU use. The GTX 560 freed up around 4% (on average) of CPU performance for other tasks while the encoding was taking place.
