AMD launched the HD6990 today, and KitGuru was at hand to analyse the reference board. We know that discerning readers of KitGuru will want to see how two of these video cards perform in a Dual CrossFireX configuration.
We will be putting two HD6990's through their paces across single screen, and four screen configurations and comparing them against many of the mainstream boards available on the market today.
Just how insanely fast are two of these cards when paired up? How hot do they get? Can you live with the noise and how much power do they need? All of this will be answered in our second HD6990 launch article.
The AMD HD6990 is a monster video card, it features 4 GB of GDDR5 memory on a 256 bit memory interface with 3072 stream processors and 192 texture units. We will find out today if it is the new performance leader.
