Stress Test - 0xAA / 0xAF
Do note that because the timedemo in the "stress test" is rather short, the real-time line graph benchmarks may show less data that usual.
All four cards perform very similarly here, with the averages only varying about 10 fps. The X800 Pro was the slowest performer. The NVIDIA Ultra and GT cards both kept pace with the XT PE from ATI and actually had higher maximum frame rates.
Again we see NVIDIA competing very well against the ATI cards leaving the X800 Pro as the only card with an average frame rate under 100 fps.
And here we see the first instance of the X800XT PE leaping over the competition. It has a higher average frame rate by 14% over the next fastest card, the 6800 Ultra. Notice that the X800 Pro comes in last however, as both the NVIDIA cards out perform it. Now let's see what happens when we turn up the visual quality.
