The Card


The HD 7990 uses three large fans that cover pretty much the whole card. The card is 30.5 cm long and 11 cm high.


AMD's HD 7990 (top) is the same size as the HD 6990 (2nd from top). The HD 7970 is a bit shorter, but the GTX Titan (bottom) is the shortest of them all. This might be important to people building a powerful mini-PC gaming rig, since such a rig would have a limited amount of available space.


Installing the card requires two slots in your system.


Display connectivity options include one DVI port and four mini-DisplayPorts. You may use all outputs at the same time, so triple-monitor surround gaming is possible with one card.

The GPU also includes an HDMI sound device. It is HDMI 1.4a compatible, which includes HD audio and Blu-ray 3D movies support.


A single CrossFire connector is available, which would allow you to combine up to two HD 7990 cards in a multi-GPU configuration. The HD 7990 can also be CrossFired with any other Tahiti-based card: the HD 7970 GHz, HD 7970, HD 7950, or HD 7870 based on Tahiti LE.
