AMD Readies "Tahiti" Based Radeon HD 7800 Series Product

    AMD is reportedly working on a new performance-segment GPU in the Radeon HD 7800 series, based on the 28 nm "Tahiti" silicon (which goes into making HD 7900 series products). The so-called "Tahiti-LE" silicon could help AMD plug a hole between the HD 7870 GHz Edition and HD 7950, getting close to the performance-level of GeForce GTX 660 Ti, at a lower cost. According to a HT4U.net report, AMD is deciding against referring to the new chip as "HD 7930," since the 7900 series is already crowded with five models, and would rather name it something along the lines of "HD 7870 OC."

    A similar approach was adopted by NVIDIA in the recent-past, when it created the GeForce GTX 560 Ti 448-cores, using higher-end GF110 silicon to create an SKU traditionally based on GF114. At this time, one can only speculate what the new HD 7870 specifications sheet could look like. Since "Pitcairn" already achieves clock speeds in the 1 GHz range, AMD is left with other features to tinker with. 1536 GCN stream processors seem like a middle ground between the 1280 SP-laden HD 7870 "Pitcairn," and 1792 SP HD 7950. Memory bus width is another component. The new desktop SKU could launch in mid-November. The new SKU could even be a "limited-edition" for the winter shopping season, much like the GTX 560 Ti 448-core.

    The 7870 and 7950 are so close in performance as is

    Not sure they really need to do this. As mentioned, 7870 and 7950 aren't too far apart, a 7870 with a medium overclock can hit 7950 performance levels iirc.

    The 8 series cant be too far away....... maybe they have a bunch of tahiti cores that didnt make spec for the 7950-7970. Or maybe they just want to kill the 660, mid-range gpus are very important for both companies.

    A Tahiti LE that can unlock shaders to a 7950/7970 at a decent price would be nice IMHO

    This sounds much more plausible to me.

    How bout designing there to be no hole from the beginning? Just nuts there was that huge of a hole there to begin with. Come on AMD, you can do better...except on drivers :p

    Can't unlock any 7000 series card afaia. No reason to think that the 7930 will be any different.
    Closer to March 2013 than today, and they certainly wont be here for the holiday buying season
    Yes and Yes. Although I wouldn't rush out and buy one. The HD 5830 and GTX 465 should represent what kind of white elephant you end up with when trying to wring too much out of a salvage GPU...top tier power consumption allied with third tier (or fifth, taking into account the GHz Ed.'s) performance, and leprosy tier resale value.

    Yeah, call it 7930, or GTFO.

    to be completely honest, AMD GPU naming scheme is too damn complicated hahaha...

    the way i understand it they have a 7950 and a 7870 and now they want a 7930 buts its gonna be squished right in betweeen the two mentioned and could also be a 7890 or whatever the hell they want as long as the number falls inbetween ?????? i don't get it lol

    I just don't get the need for 4 digits, yes NVIDIA did it but they only utilized the first 2 and the 3rd COULD be used to designate a modification... that made sense

    a 690>680>670>660>650>640>630 THIS MAKES PERFECT SENSE

    7970>7950>7930>7870>7850>7780 this is dumb, yes they are in numerical order buts its like what were they smoking when deciding to increment by 20's when your model number is in the 1,000's LOL

    Are you serious? Nvidias' naming scheme makes sense to you despite the numerous Ti and variants in between the product lineup (none of which use the third number by the way) and AMDs' naming scheme which has no such thing does not?
    WaroDaBeast says thanks.

    A bit late to be worrying about it now. Can't be any more confusing than the XT, XTX, Pro and XL suffixes of yore. Not to mention the untruth in advertising for both Nvidia and AMD/ATI:

    LE : Limited (appeal) Edition
    SE : Special (needs) Edition
    PE : PR only Edition

    how lucky you were you could have a SE that was a 9800 Pro that was locked to meet certain market criteria

    It's simple:
    First number: generation
    Second number: class
    Third number: modification

    I'm setting my expectations really low. AMD's third-tier chips usually are third tier for a reason and don't make sense to buy. They in the past have had horrible performance/watt compared to similar performance cards (HD 4830, HD 5830) or are so close in performance to the next lowest card that they don't justify their price (HD 6790). NVidia has been hit-or-miss with third tier chips (GTX 465 and GTX 460/560 SE were bad, GTX 560 TI 448 and GTX 660 TI were good), but considering AMD's record, I can't get excited.

    Don't forget the SE, GT and GTO suffixes.

    X800, X800 SE, X800 GT, X800GTO, X800 Pro, X800XL, X800XT, X800XT Platinum Edition.

    Brilliant.. :laugh:

    Don't forget that there was an X800 GTO2, and AGP and PCIe versions of each card you mentioned as well. Whoever thinks that naming today is extremely confusing doesn't remember the past.
