AMD ATI Radeon HD 6990 4GB GDDR5 PCIe
The AMD ATI Radeon HD 6990 is a massive graphics card measuring in at 12 inches long (30cm) and weighing a little over 1kg. The heatsinks are separated by a blower fan which is positioned in-between them rather than at the end of the card. The Radeon HD 6990 has an impressively low 37-watt idle consumption. The GDDR5 memory works at 5000MHz (1.25GHz x 4) on this particular model and features a 4GB capacity.
