    Cayman XT. XT = HD xx70, Pro = HD xx50
    Why? These cards are tweaks of an existing architecture. Expecting some kind of massive performance jump using the same arch at the same process node doesn't happen anywhere except the wet dreams of fanboys.
    Because then one side can put their best single card (regardless of the fact that it runs 2 GPU's) up against the other sides best single card and chant "Mine's bigger" (see HD4870X2 v GTX 280, GTX 295 v HD4870X2, HD 5970 x GTX 480 for historical comparison).
    And No, Antilles won't be Cayman based. Antilles (HD6990) will likely be dual Barts XT (HD 6870)with either GPU's binned for high leakage and/or downclocked to meet the PCI-E specification of 300 watts.
    Barts XT = 163w x 2 = 326w...right ballpark for dual GPU once cherry-picked GPU's are used
    Cayman Pro = ~215w x 2 = 430w...Fail.....although these is the supposed GPU's to be used in Antilles- so either the power spec is a lot lower than what's being reported or the clocks are very much lower than the 6950 card.
    Cayman XT = 230-255w x 2 = 460-510w....Fail² (This theoretical card would require three PCI-E 8 pin power sockets).

    And no (again), neither AMD nor nvidia will break the PCI-E specification with a reference card. Doing so means that OEM's (Dell, HP, iBuypower, Cyberpower, Puget etc.) won't touch the card with a bargepole.
    Riiiight. So a fully functional 6970 is showing similar performance at the moment to the GTX 580, but you think a salvage part with reduced shaders is going to be better still.
    Congratulations, I think yours is the only post I've read on any site or forum that seems so confident about Cypress Pro.

    EDIT: Fudzilla is reporting that Antilles will likely be a dual 6950 sourced part.

    looks good, wonder how bad would it break my bank?

    Yes, yes... I like this competitive card releasing. It helps bring the price down on already solid cards. I bought a 1 gig version of the GTX 460 as soon as it was released, and I already see prices going down fairly quick.

    This change in naming has me all sorts of confused, especially with some of the benchmark reports I've been seeing around the internet. From some sources, these new cards actually underperform the 58xx series, even though they have a higher number.

    haha, this is insane

    Welcome to the world of marketing. Be thankful you don't live in Eastern Europe.

    Looks like the release date is slipping to 13th December. Cutting it a little fine for Christmas.
    Smells like bs.
    So strong that AMD release the HD 6870 to all but kill HD 5850 sales stone dead, while HD 5870 sales have been sluggish for some time- hardly surprising given the pricing compared with the 5850 (and now the 6870).
    Newegg shows only 5 of 11 HD 6870 SKU's in stock- the volume part of the deal must be AIB partner specific. Prices seem to be trending upwards as well.
    So, as far as AMD are concerned, no component shortages, and the GTX 580 launch/performance level are definitely NOT the causes for the delay.......m'kay

    A guide to pricing on these cards...
    Overclockers.uk (see post #69) informed its forum members that the 6970 will be a £400 (inc tax) part, while the 6950 will be priced at £300.
    For comparison, the etail Overclockers.uk site lists the GTX 580 starting at £430 and GTX 480 at £294 (likely to be the GTX 570's approximate price point also)
