Radeon HD 7950 Specifications Leaked
Last Thursday, AMD launched the Radeon HD 7970 graphics card based on its new 28 nm "Tahiti" silicon, but it remained tight-lipped about the specifications of the more important SKU that will be based on it, the Radeon HD 7950. The HD 7970 will carry a launch price of US $550, making the HD 7950 an SKU to watch out for. According to details released by XTReview, the "Tahiti Pro" or HD 7950 will be carved out this way:

- 1792 stream processors, 28 GCN compute units
- 112 TMUs, 32 ROPs (derived)
- 384-bit GDDR5 memory interface
- 3 GB memory, memory clock around 5.00 GHz

Now seriously, anyone else is curious why Nvidia's still lurking in the shadows ? All the news lately have been about the 7k series. Is Kepler going to be an epic ? Or is the gain's so minimal it would outshine Bulldozer's fail ? Someone gimme some news, I'm dying here !
I mean, we could also ocnsider that there is also a 45 MHz core bump, and a rather significant memory bandwidth boost. An architechtural analysis would b very interesting, IMHO.
does that mean GCN is less efficient/powerful than the old architecture ???
Also, teh "stream processors" are of a very differnt type, and I'm sure cache organization has changed as well. It's quite a different beast, and drivers probably need some work as well.
The real fact of the matter here is that these cards are not really meant for single-monitor use. A 6950 is fast enough for that. These cards are intended for high-resolution use, with multiple monitors, and are simply by nature of designing for that, good for other stuff as well.
That's why they are priced so high...they are for high-end performance, not really anything else(Uh 3GB for VRAM??:laugh:). I'm sure performance charateristics when under high-resolution loads may paint a different performance picture.
Although, the documentation I've see nfor Eyefinity performance seems a bit, well, biased.

Its most likely that the same damned 32 ROPs are holding the card back more than anything.
It is quite evident that even the 5850 is almost as fast as the 5870 clock for clock, and this is also true for the 6950 and 6970.
They keep slapping more shader power on these cards without addressing the most likely bottleneck.
Forget the hunger
Forget the wars
I want the HD7950 to unlock to HD7970
Thank you, amen.
Is this series of cards looking like a quick "refresh" series similar to the 8000 to 9000 series Nvidia did?
Although I'll more than likely be skipping this generation all together...probably....maybe...:laugh:
2048/1536 *100 = 133%
or
2048 - 1536 = 512 // 512/1536*100 = 33%
HD6970 has 25% less shaders.
I blame my fail on it being christmas! :laugh:
Do you guys think a 7950 would run on a 500w psu with an overclocked 2500k? I am currently running it with a 6870 that has a mild OC.
edit: also hopefully by march nvidia will have their next generation out so card prices will reflect competition.
