We got confirmation that Radeon HD6990, AMD's dual-chip board codenamed Antilles won't surface until Q1 2011, and we know that we've said before. This is an update. Despite original plans to launch the dual-GPU card based on Northern Islands in Q4 2010, it looks like AMD has decided to postpone this product till Q1 2011.
We don’t know if this is a business decision or that they have some issues but it doesn’t look like we will see Nvidia's dual chip card this year either.
AMD's graphics partners are not happy as they will miss the Xmas shopping spree before these cards arrive, but traditionally this part of market will wait for its product as a single chip is simply not an option for them.
You can only imagine how hot these card can end up as they will have two massive chips to power, but I guess this market will forgive the slight noise as long as the card perform as they are expected.
Cayman-based Radeon HD 6970 and HD 6950 should be the last cards to launch in 2010 and everything else follows next year.
