The AMD Radeon HD 6990
Below we have an overall look at the AMD Radeon HD 6990 reference model.
This video card has one DVI-D and four mini DisplayPort connectors. All Radeon HD 6990 video cards will ship with three adapters: one mini DisplayPort to single-link DVI-D (passive adapter), one mini DisplayPort to single-link DVI-D (active adapter) and one mini DisplayPort to HDMI (passive adapter). This will allow you to use the mini DisplayPort connectors even if your video monitor doesn’t support this kind of connection, which is probably the case.
The Radeon HD 6990 requires two eight-pin power connectors, shown in Figure 4.
