Rumor: Radeon HD 7990 Set to Launch After Nvidia's Kepler
With Nvidia's new Kepler set to release this month, we are now hearing that AMD has the Radeon HD 7990 ready in the wings.
Right before the New Year, we learned about the upcoming "New Zealand" graphics card, which is based on two "Tahiti" HD 7900 series graphics chipsets. With Nvidia set to release its first 28 nm based Kepler card later this month, Fudzilla reports that AMD plans to launch the Radeon HD 7990 just weeks after NVIDIA introduces its new GeForce GTX 680.
Though the final specifications are not known, it is rumored the HD 7990 will feature a core clock of 850 MHz, memory clock of 1250 MHz (5 GHz effective), 6 GB GDDR memory (3 GB per GPU), with 384-bit (x2) memory bus. It will be based on a PCIe 3.0 interface and support for DirectX 11.0 and OpenGL 4.0. In addition, the card will include 62 compute units for a total of 4096 (2048 x2) stream processors, 256 (128 x2) texture units and 64 (932 x2) full color ROPs.
The one thing we do know based on past experience with AMD's dual-GPUs, is the Radeon HD 7990 will be 1) expensive (suggested price around $850 dollars) and 2) a lengthy graphics card (over 11.5 inches). For those Nvidia fans, I wouldn't worry too much, as it is rumored that Nvidia already has its own dual GK104 card ready to counter attack.


Don't like Radeon products? Don't post. Pretty simple. Until real world benchmarks (not NVIDIA based marks) come out for the 680, the 7970 is still king in single GPU setups.
i agree with ubercake, the dual gpu card won't work at it's full potential without good driver support from amd. good driver support is something amd has been historically bad at. what's worse, if amd doesn't release working driver during a high profile game launch and if the game doesn't support cfx at launch, the 7990 user would be screwed till driver and game updates come out.
edit: i haven't used a dual gpu card. i don't know if it is possible to shut down one gpu in case a game does not support dual gpu/crossfire.
Breaks it - i'd agree on that sadly. Took several weeks to get descent xfire support in Skyrim, and with that kind of blockbuster title it should have been present at release day. Not weeks after. Incompetence or ignorance towards their customers, i don't know either way its bad. I hope they make good on their promises to speed up the adaptations of new titles this round, not like the last that was pretty much only BS!

[edit] tried to tell fudzilla this but their contact link is broken... you have to do some math to avoid a "spam check" but even if you put in the right number it says you failed the check LOL must be using an AMD processor on the server [/edit]
Granted 7970 is a nice card.
Now Nvidia goes out of their way to make drivers work for their cards. Nvidia tends to be friendlier with games then AMD does.
I looking to run a 3d, Eyfinity/Nvida Surround setup sometime before June! to complete my z77 build.
I got $5k to burn!!! any suggestions??? x79?, z77?, 3x GTX680's?, 2x GTX 690?, 2x AMD 7990's?, 24-27in 3D Monitors x3???
well.. not only drivers, the good of nvidia is always they made everything works.. nothing features are broken.

I believe that should be 64 CUs since the 7970 has 32 CUs for 2048 SPs.
