    Whats the problem with this chip ? Remember the hd5770 is a $200 chip that has been cost reduced. This is a $150 chip. Its quite a bit faster than the hd 5750 that was in this market before .

    Its not going to get 5770 owners to upgrade but those with older 4x00 cards its a good upgrade .

    Amd already has a great hd5770 replacement card in the 6850s

    I'm talking about this card running at 1GHz (equal performance to a 6850) with no problem at all (at least ours model does) and.. I haven't even talked about.. dare I say it.. unlocking?*


    6790 is a little gold nugget but nobody actually went the distance with this card yet. Maybe because everyone assumed it was another 5830.. nobody even tried?







    *yes that works!

    I've seen reviews trying to flash a 68X0 bios on it, with no success.

    flashing also isn't the answer on non-ref 6950, yet the success rate of edited bioses on non-reference cards is over 95%

    It's really like no one even tried.

    That seems a good OC - those I've seen were more about 950Mhz. This is what I expected, given the cards run at the same voltage range as the HD 6870 (which also explains the quite high TDP). Though even when overclocked to 950Mhz it still can't beat the HD6850 (which also will OC), it still has much higher power consumption and is still just not that much cheaper.

    Now THAT is interesting. I assume though you are talking about simds? Unlocking ROPs would likely help more. And no I haven't seen anything if and how it's done...
    Still, that doesn't really help that much imho. An unofficial feature, which might not work at all on most retail cards even if it does on review cards.

    Word of mouth about unlocking seems to draw enthusiasts-on-a-budget like moths to a candle though. It did with Radeon 9500, X800 Pro at least.

    It also increases sales of $300 6950s, I imagine, due to a perceived increase in value. Well, actually it is a somewhat tangible increase in value. ;) I bought my 6950 before the unlock was figured out and I'll say it's pretty uplifting to learn that you can unlock all the goodies in your artificially gimped-for-the-market product.

    So, a shader unlocking script is the answer? I guess that means the missing ROPs will be eternaly lost then... Someone needs to tell W1zzard. :)

    But it also says the SIMDs are fused off. So if it's possible at all, the success rate could be not so high.

    Hm, over here, price search engine geizhals says, HD 6850 is just 16% (18 EUR) more than 6790 (that's cheapest in stock), I'd say that doesn't make 6790 very attractive.

    I've just been assuming that Cayman isn't an organic product. ;)

    Hmmm how can they "accidentally" not blow some fuses? I want to see tests of the 24 ROP edition. Would be interesting, sort of like a 4870 with 24 ROPs.
