PCI Express Bandwidth Testing and Video Performance
As far as the interface is concerned, the PRO and XT are created equally. The same goes for the video processing performance (bar a slight difference if the pixel shader units are asked to help with video processing). So I'll skip talk on these parts of the testing, since I covered it in the first article. Find all that here. Here are the graphs, for completeness.Host-to-GPU texture upload performance
