But I recall reading a comparison review between the 9500 pro (which I have)
and the 9600 (non-XT) and the conclusion was that the 9500 pro was better
due to the fact that it has 8-pixel pipelines and the 9600 has only 4.
Because of this the 9600 didn't benchmark as well even though it has a
higher core clock frequency than the 9500 pro. Here are some review links
that compare and contrast the two:
