    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
    The core clock speed, the exact memory clock speed, and more importantly, the target price-point, remain unknown. The Radeon HD 7950 is expected to be launched on the 9th of January.

    It will be interesting to see where it falls. If it's as fast as a GTX580 (who knows?) and they price it lower then it will be bad news for NV. If it's built in the same design with same cooler, surely should be quieter too.

    Im wanting to pick up a 1.5gb 7950 if they ever see the light of day. I think that should more then enough to push 4800x900 eyefinity.

    I'm a little confused here :confused: ... the 7970 has 33% more streaming processors and more memory bandwidth than 6970 ... but its only around 30% faster than the 6970 ... y is that ... ??? may be im missing something ... :eek:

    This will be like AMD's version of a overclocked GTX 580 or GTX 585 but more bang for buck ^_^, uses less power, more quieter and efficient ......Well hoping anyways!

    I think it will fit between the 570 and the 580. Though I think the pricing would be that of the 580. Of course the price justification would be backed up by hand picked benchmarks of games where AMD GPUs excel at.

    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 has all this extra, but consumes less power. That's enough of an excuse.



    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.

    Im not well versed in the tech stuff ... but just asking :D ... suppose the 7970 has the same amount of streaming processors, same memory, same core/memory clocks like the 6970... then ... it'll be slower than the 6970... right ??? so only possible +ve factors will be less power and less heat and the new features ... :confused:

    does that mean GCN is less efficient/powerful than the old architecture ???

    Can't tell ya...I don't ahve a card, so cannot bench it with the programs I am familiar with.


    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.

    Evidently the memory bandwidth is overkill, so only more stream processors are increasing performance anything remotely like linearly.

    So, 6970 speeds for more money. Doesn't sound very win to me.:ohwell:

    It should be above 580 at 450$ as you can see in the link I posted. There's the 7890 that will fit with the 570 and the 6970, more expensive though.

    More like the other way around :ohwell:
    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.

    The 7970 has 25% more shaders not 33.

    I haven't been paying much attention to the 7xxx series posts but could someone just give me a Yes/No answer to my question?

    Is this series of cards looking like a quick "refresh" series similar to the 8000 to 9000 series Nvidia did?

    Would love to see this as well. I jumped on my first 6970 on launch day only to find out 6950's could unlock about a week later...:slap:

    Although I'll more than likely be skipping this generation all together...probably....maybe...:laugh:

    It has 33% more shaders than the HD6970.

    2048/1536 *100 = 133%

    or

    2048 - 1536 = 512 // 512/1536*100 = 33%

    HD6970 has 25% less shaders.

    Perfect. Just in time for my birthday.

    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.
