Asus AX800 Pro (Radeon X800 Pro)

We've done a few comprehensive image quality comparisons in some recent video card showcases (see: here and here), so we won't go too in-depth here.  But because we tested all of the cards in this article with new drivers, we decided to snap off a few screen shots with Aquamark 3 to give you an idea of their in-game image quality.  We took screen shots using all four of the configurations we used while running our suite of benchmarks...

Screen Shot Comparisons Whip Out The Magnifying Glass!

6800 No AA	6800 4X AA	6800 4X AA/8X Aniso	6800 4X AA/16X Aniso
6800GT No AA	6800GT 4X AA	6800GT 4X AA/8X Aniso	6800GT 4X AA/16X Aniso
X800 No AA	X800 4X AA	X800 4X AA/8X Aniso	X800 4X AA/16X Aniso

The screen shots above are of frame 5000 from the Aquamark 3 benchmark.  We set the resolution to 1024x768, and took these shots at the four different configurations we used for most of our testing (No AA, 4X AA, 4X AA + 8X Aniso and 4X AA + 16X Aniso).  If you open up multiple images and switch between them (pay attention to the file names in your browser's address bar to keep track of which shot you're looking at), you'll see very little variation from card to card.  However, if we zoom in a bit, some differences are revealed...

6800 4X AA (300%)	6800 4X AA/8X Aniso (300%)	6800 4X AA/16X Aniso (300%)
6800GT 4X AA (300%)	6800GT 4X AA/8X Aniso (300%)	6800GT 4X AA/16X Aniso (300%)
X800 4X AA (300%)	X800 4X AA/8X Aniso (300%)	X800 4X AA/16X Aniso (300%)

This group of screen shots represent a 300% zoom of the center of the full scene.  As you can see in each shot, with Anisotropic filtering enabled, much more detail is brought out in the hill at in the center.  It's nearly impossible to see any differenced between the 8X and 16X aniso shots though.  And when comparing one card to another, there are virtually no differences between the three different settings on the GeForce 6800 cards, but comparing a 6800 with the AX800 Pro/TD reveals a bit more detail on the 6800s.

6800 No AA (300%)	6800 4X AA (300%)	6800 4X AA/16X Aniso (300%)
6800GT No AA Aniso (300%)	6800GT 4X AA Aniso (300%)	6800GT 4X AA/16X Aniso (300%)
X800 No AA (300%)	X800 4X AA (300%)	X800 4X AA/16X Aniso (300%)

We also zoomed into a different portion of the screen to spotlight some differences in each card's anti-aliasing technique.  When we enabled 4X anti-aliasing, the antennas above the station and the edge of the track at the right are cleaned up considerable.  Once again, there were virtually no differences between the two 6800s, but the X800 Pro produced a slightly different image.  The X800 Pro seemed to do a slightly better job at cleaning the jaggies, but it's not a major different by any means.  With both NVIDIA and ATi using adaptive trilinear filtering, and using similar anti-aliasing techniques with this generation, it's become much more difficult to say one card has better image quality than another.
