3DMark05
Starting off with a look at performance in 3DMark05. The two lines to take special note of are the green and black lines that represent the ABIT Fatal1ty X800 XL 512MB card run at 400MHz/980MHz (stock-clocked X800 XL 512MB) and 420MHz/1100MHz, ABIT's XTurbo frequency. In this illustrious company, the X800 XL remains some way behind the others.
The I.Q. benchmarks take in our regular 4x AA and 8x AF settings at all resolutions. The usefulness, performance-wise, of a 512MB framebuffer is reckoned to be at th very highest I.Q. settings, which is 6x AA and 16x AF for ATI-based cards. GeForce cards don't offer an identical setting and performance at their respective highest I.Q setting, 8xS AA 16x AF, is hugely hampered by the need to supersample; that's why it's not included.
The XTurbo Fatal1ty X800 XL 512MB still cannot overcome the performance of a similarly-priced X850 XT, though, which runs with a much faster core clock and slightly higher memory speed.
