Super AA (Anti-Aliasing)
The Super AA mode provides even higher quality anti-aliasing on
multi-GPU systems. It works by having each GPU render the
same frame with anti-aliasing enabled but using different sample
locations for each. When both versions of the frame are
completed, they are blended in the CrossFire Compositing engine.
The resulting image is twice the number of samples, so 4x and
6x AA become 8x and 12x Super AA respectively.
Graphics Cards Requirements
1. One Radeon
®
X850 / Radeon
®
X800 CrossFire Edition graphics
card.
2. One standard PCI Express Radeon
®
X850 or Radeon
®
X800
graphics card.
The Radeon
®
X850 CrossFire Edition card works with any
standard PCI Express Radeon X850 graphics card (Radeon
X850 PRO, Radeon X850 XT or Radeon X850 XT Platinum
Edition) from ATI or any of its partners including cards previously
sold.
The Radeon
®
X800 CrossFire Edition card works with any
standard PCI Express Radeon X800 graphics card (Radeon
X800, Radeon X800 PRO, Radeon X800 XL, Radeon X800 XT
or Radeon X800 XT Platinum Edition) from ATI or any of its
partners.
Note:
If the clock speed of the CrossFire Edition graphics card and
standard PCI Express graphics card are different, both cards will
operate at their individual clock speeds.
