Good news for AMD fans, the Antilles dual chip card will end up with two Cayman chips, something that promises that the card can end up significantly faster than dual-chip Radeon HD 5970.
Two Barts (Radeon HD 6850 or 6870) class chips would not be enough to provide a sufficient performance lead for the new Radeon HD 6990 X2 card. This is why ATI is using two Cayman chips and we also learned that the chip looks more like the Radeon HD 6950.
The funny part is that we still don’t exactly know what is behind Cayman, but we are doing our best to find out before November 22nd, the alleged launch date.
We expect TDPs around 300W but this is something that can only be confirmed at a later date. It will be very fast, that is certain, but we still don’t know who will win this winter graphics update showdown.
