    But it is backed up by the huge PHYs evident on Tahiti die shots and Dave Baumann has said here in the forum, that Pitcairns PHYs are just a bit more than half the size or so (per 128bit segment) compared to Tahiti.
    You will probably run into the limits of the memory controller before you hit limits of fast GDDR5 chips. I guess it's close to impossible to hit memory speeds significantly above 6GBps on a Pitcairn style interface no matter what chips you connect to it.

    Do any of you wonder if Hawaii has been finished for awhile but AMD has been sitting on it, milking Tahiti to the limit?

    Why the sigh? Don't leave us guessing!

    Because it's basically a rebadged 7870 @ $199, you can buy current 7870s lower than that.

    You can also buy plenty of 7870 that are more expensive.

    Perhaps, but I'm wondering if AMD wasn't just reserving the wafers allocated for Hawaii just in case the XBone and PS4 chips needed a bit more.

    Once they saw they had good enough yields for the console chips, time to launch Hawaii.

    Just a theory. :smile:

    Congratulations for pointing out the obvious, did you also know that many 270X cards will cost more than $199? shocking isn't it.

    My point(which i thought was obvious) is that the $200 range has not improved over what is currently available, if you take into account some 7950 prices it has gotten worse.

    As a new generation only the 290/280 series seem to be an improvement, which is quite sad.

    What I'm not getting is how does this work
    - R7 240/250: Oland, CI/No Audio
    - R7 260: Bonaire, CI/Has Audio
    - R9 270: Curacao, should be VI since there hasn't been Curacaos before, but No Audio. If it's re-named Pitcairn, why was it renamed? Tahiti wasn't?
    - R9 280: Tahiti, SI/No Audio
    - R9 290: Hawaii, VI/Has Audio

    The 260 and 270 simply don't fit the scheme here.

    At first glance it does look that way but the value proposition will look a lot different when we see the boost in performance Mantle will give to all of these GCN based cards.

    It could also be that they know Nvidia has nothing coming down the pipe to drive their current prices down. And let's not forget launch prices of the 7870 and 7850 were $350 and $250 respectively.

    It's as if the 270X isn't substantially cheaper to produce than HD 7870, or that the supply demand situation of the 270x isn't much more different than the HD 7870. Shocking.

    My guess is that Bonaire was created from the Xbox One testing & Curacao XT was created from the PS4 testing.

    Bonaire being the same as the Xbox One design = already customized to have a on chip Audio processor but instead of the Xbox One audio processor they used their own audio chip.


    Bonaire & Curacao are the only 2 Sea island chips that I know of & they both just so happen to be around the same specs as the Xbox One & PS4 minus 2 CU's for redundancy.

    Edit: I forgot about Oland.

    Oland is Sea Islands like Bonaire, Curacao, based on name, should be Volcanic Island

    Price points almost never change with a new launch, aside from the HD 4000 series. AMD and NVidia price the new parts with a fair value of what they'd fetch in the existing market. Prices go down afterwards.

    The review says that it's still the same chip.

    Techreport:
    "One thing that may make grabbing a Radeon HD 7000-series card on clearance more attractive is the Never Settle Forever bundle that lets you pick two or three titles from a list of pretty decent games.
    The new R-series Radeons won't take part in this program."

    Well within 3d
    What's with the code name reapplication?
    I could be snarky or disappointed, but mostly snarky.
    But I'm not.

    Just, why?



    Why?
