    HD 6770 is rumored to be about 10% faster than counterpart GTX 460, almost as fast as HD 5850

    Enhanced Tessellation unit (x2?), 4D VLIW core, 2 x 6-PIN PCI-E Power, Dual Slot form factor

    While all of these values are within believable ranges, I can't help but notice that you didn't link any sources

    Well, someone is wrong, we'll find out soon enough who.


    A few bit numbers and shader counts are irrelevant anyway. Anyone could have guessed the numbering scheme.
    The real questions would be:
    a) The 6770 specs you claim are similar to the 5830, both in speed and power draw (two connectors!). Will the improvements of SI cards against an equally fast evergreen part be noticeable? Both are 40nm, and there are limits to architecture-based improvements.
    b) what will they cost? Evergreen prices are bound to drop, so which generation offers the best value for your money?

    Of course, noone wants to answer them. AMDs silence may be a bad sign. On the other hand, their GPUs are currently winning, and they wouldn't kill their evergreen margins if they didn't have some substantial improvements.

    As usual, we'll have to wait until the actual release. Shouldn't be long now..

    This does not agree with the GPU-Z screenshots which were posted earlier and which showed only 256-bit GDDR5 for 6800 series.

    Nothing to worry about - we didn't talk about the previous generations of GPUs before launch either.

    Even the Fusion APU information released so far has been pretty much CPU only (other than the fact that the Fusion APUs have DX11 graphics), and there's usually a thumb over the GPU portion of the die shots

    oh, my biggest worry is that my shiny HD5770 is obsoleted before there's usable OSS support. You'll want me to keep worrying
    (I won't upgrade soon, anyway. My card serves me well and jumping to next-gen will only delay the ETA for OSS drivers.)

    The thing is, I knew pretty much everything about the 5770 before it was launched, including the date when you'd reveal what everyone knew already. Of course the lack of information now is not due to a change in PR, but rather a successful game of whack-a-mole. Sure, it's preferable to announcing specs for a <200W GPU in september and delivering a >>250W GPU in april.
    Still feels.. odd. Hunting down the small bits of information and piecing them together was kinda fun

    Fudzilla says the Radeon HD 6000 series may just be an incremental improvement release: Link
    If this is true, the open-source driver may be a bit quicker to appear this time around.

    Electronista hints at a November release date.
    Time will tell if these rumors are true or not.

    1280 4d shaders means 320 shader units, same as 5d 5870.
    and 1920 is 480

    I hope the thermals are not that bad. Thermals are important to me.

    i think funkyrider fails here

    a hd 2900 do have 512 bit interface and more bit on interface and this does a card not make better.

    384bit interface is a complete nvidia style bullshit.

    the hd67xx do have 256bit and 160gb/s gddr5 and the 6870 do have a 256bit interface and 205gb/s gddr5 ram.

    a 20% faster card do not need a 300gb/s interface

    and the 4D shader man what are you smoking this is not nvidia!..

    on the driver side i know the diverence is not so big so the opensource driver will come fast.

    this means no there is no 4D shader core.
