The AMD Radeon HD 6990, otherwise known as Antilles, is a card we have been expecting for some time now. In what’s become a normal AMD fashion, when they first introduced the Radeon HD 6800 series back in October, they also provided a rough timeline for the rest of the high-end members of the family. Barts would be followed by Cayman (6950/6970), which would be followed by the dual-GPU Antilles (6990).

AMD’s original launch schedule at the time was to have the whole stack out the door by the end of 2010 – Antilles would be the last product, likely to catch Christmas before it was too late. What ended up happening however is that Cayman didn’t make it out until the middle of December, which put those original plans on ice. So we ended up closing the year with the 6800 series and the single-GPU members of the 6900 series, but AMD did not launch a replacement for their flagship dual-GPU card, leaving AMD’s product stack in an odd place where their top card was a 5000 series card compared to the 6000 series occupying everything else.

So while we’ve had to wait longer than we anticipated for Antilles/6990, the wait has finally come to an end. Today AMD is launching their new flagship card, retiring the now venerable 5970 and replacing it with a new dual-GPU monster powered by AMD’s recently introduced VLIW4 design. Manufactured on the same 40nm process as the GPUs in the 5970, AMD has had to go to some interesting lengths to improve performance here. And as we’ll see, it’s going to be a doozy in more ways than one.
