Today ATI unveils their answer to SLI: CrossFire. Beyond 3D take a short look at how CrossFire fits together and some of the unique rendering modes offered with it

With Super AA mode each of the two boards will be rendering the entire frame, effectively they will be duplicating the workload, however one board will render with one FSAA sample pattern whilst the other board will render with an alternate sample pattern. Each board will then resolve the FSAA samples down to the display resolution and both images will be send to the compositing device on the master card two blend each of the pixels from the two images together, which gives a resultant colour value from the two boards that equates to the same value as though they were calculated on a single board at the higher level of FSAA.
