The Card

AMD's Radeon HD 6990 is a huge card, which is about the same length as the Radeon HD 5970. ASUS has added a metal plate on the front - instead of the colorful stickers other AIBs use. A small ASUS logo highlight adds to the stylish appearance of the front of the card.


The card requires two slots in your system.


The card has one DVI port and four mini-DisplayPort ports. In the package you will find numerous adapters to convert a DP output to DVI or HDMI. AMD's display output logic is clearly superior to what NVIDIA has to offer at this time. Vendors are free to combine six TMDS links into any output configuration they want (dual-link DVI consuming two links) - and use them all at the same time. AMD has also introduced DisplayPort 1.2 support with their new cards which allows the use of a DisplayPort hub to connect multiple monitors, or daisy chain them together.

An HDMI sound device is also included in the GPU. The HDMI interface is HDMI 1.4a compatible which includes Dolby TrueHD, DTS-HD, AC-3, DTS and up to 7.1 channel audio with 192 kHz / 24-bit output. The new revision also brings support for Blu-ray 3D movies which will become important later this year when we will see first Blu-ray 3D titles shipping.


You may combine up to two HD 6990 cards from any vendor in CrossFire. More on the yellow sticker on the next page.
