Photos of AMD’s highly anticipated Radeon HD 6990 Antilles GPU recently hit the news circuit and created lot of stir. Now the company has come through officially with details, only some mind you, and specifications of the card, and these are definitely impressive.
As has been known for several months now, the Radeon HD 6990 is a dual-GPU graphics card and is planned to be the successor to the Radeon HD 5970. The card will boast of two Antilles graphics processing units (GPUs), each manufactured on a 40nm base. The twin-GPU configuration will increase the number of cores to a massive 3,072 stream processors.
To swing such numbers, AMD will be weighing the card with lot of memory - 4 GB, all of it GDDR5. The memory modules are connected to the GPUs through two interfaces, each of 256-bit. AMD also revealed that the HD 6990 will have two PCI Express power connectors - an 8-pin one and a 6-pin one. For dual-card configurations, the HD 6990 has been equipped with a CrossFireX connector as well.
For display connectivity, the Radeon HD 6990 card will come with four mini DisplayPort outputs and a DVI port. To top it all, AMD has designed a single fan cooling solution with a backplate for extra heat dissipation, with the fan sitting in the centre of the board.
The only part missing from the details are the clock speeds, the pricing, and also the expected date of release. But with so many specifications available, it is only a matter of time before the final details arrive... not to mention the card itself.
