If the Radeon HD 7970 just didn’t cut it for you, it seems like you won’t have to wait long for AMD’s dual GPU card which should be known as the Radeon HD 7990, as it’s expected to arrive in Q1. So far not much is known about the specs, apart from the fact that the card will have two "Tahiti" GPUs and apparently 6GB of GDDR5 memory.The Radeon HD 7990 has so far been known as the "New Zealand" and will as the Radeon HD 6990 sport a pair of GPUs on a single card. The clock speeds will most likely be slightly lower for each GPU than that of a single GPU card, as despite the die shrink to 28nm we’re not exactly looking at a halving of the heat output by the new GPUs.
The for AMD new 384-bit memory interface should have 6GB of GDDR5 memory attached to it, as it’s hard to see AMD going for half the memory per GPU compared to the Radeon HD 7970. This adds up to more memory dedicated to a single graphics card than what you get in the average PC today.Another interesting aspect is of course AMD’s new ZeroCore power saving technology which should hopefully allow one of the GPUs on the card to be powered down entirely when it’s not needed. This should allow for a significant power saving when non GPU intensive tasks are being performed on the computer a Radeon HD 7990 card would be fitted to. We’ll just have to wait and see how things develop, but it looks like we don’t have too long to wait and if nothing else, AMD seems to be timing Intel’s Ivy Bridge platform pretty well here too, as there should hopefully be a decent amount of cards in the retail market by then.Source: TechPowerUp
