Tack för länken! Vid närmare undersökning verkar det som det inte rör sig om antalet GPUs eller busshastigheten utan just om kantutjämning. Fler GPUs fördelar arbetet och kan åstadkomma bättre kantutjämning, dvs 32x eller 64x. Enda syftet är att skapa skarpare bilder/kanter:
"The third method is SLI Antialiasing. This is a standalone rendering mode that offers up to double the antialiasing performance by splitting the antialiasing workload between the two graphics cards, offering superior image quality. One GPU performs an antialiasing pattern which is slightly offset to the usual pattern, and the second GPU uses a pattern offset by an equal amount in the opposite direction. Compositing both the results gives higher image quality than is normally possible. This mode is not intended for higher framerates, and can actually lower performance, but is instead intended for games which are not GPU-bound, offering a clearer image in place of better performance. When enabled, SLI Antialiasing offers advanced antialiasing options: SLI 8X and SLI 16X. A Quad SLI system is capable of SLI 32X antialiasing."
