We have posted in the past that AMD will be coming out with the Radeon HD 6990 in the first quarter of 2011. The Radeon HD 6990, also known by the code name Antilles, will have two Cayman chips on board. Essentially this will be CrossFire on a single graphics card. [H]ard|OCP has the AMD Radeon HD 6990 in-house and played Dragon Age II.

Unfortunately, they were not able to give out any performance numbers, as in frames-per-second. But then again, that is not how [H]ard|OCP like to do things. Instead, they like to compare graphics cards at the highest playable settings. For the Radeon HD 6990 they played the game using Eyefinity set at 5760×1200, 4X Anti-aliasing, 2X anisotropic filtering, High quality in-game settings and screen space ambient occlusion. In comparison, the Radeon HD 6970 was played at 5760×1200, 2X Anti-aliasing, no anisotropic filtering, High quality in-game settings and no screen space ambient occlusion.

We cannot tell you specifications or performance experienced with the Radeon HD 6990 today. What we can tell you is that the video card works and is in complete form. We were able to use it without any issues and play Dragon Age II demo in the DX11 rendering path. There was a distinct gameplay experience difference between the Radeon HD 6970 and Radeon HD 6990 which is encouraging.

Rumor has it that this card will be available on March 8th. Rumor also has it that the dual-GPU NVIDIA GeForce 590 is expected real soon now.
