    God damn it... I was about to hit the buy button on 5870 though 28NM looks even better.
    I'll never be able to buy a new Video card at this rate.

    You'll be waiting a long time if you hold off.

    ATI historically has tried new processes on small GPUs like when the 4770 came out. It would make sense that that's the case here as well.
    Particle's First Rule of Online Technical Discussion:
    As a thread about any computer related subject has its length approach infinity, the likelihood and inevitability of a poorly constructed AMD vs. Intel fight also exponentially increases.

    Rule 1A:
    Likewise, the frequency of a car pseudoanalogy to explain a technical concept increases with thread length. This will make many people chuckle, as computer people are rarely knowledgeable about vehicular mechanics.

    Rule 2:
    When confronted with a post that is contrary to what a poster likes, believes, or most often wants to be correct, the poster will pick out only minor details that are largely irrelevant in an attempt to shut out the conflicting idea. The core of the post will be left alone since it isn't easy to contradict what the person is actually saying.

    Rule 2A:
    When a poster cannot properly refute a post they do not like (as described above), the poster will most likely invent fictitious counter-points and/or begin to attack the other's credibility in feeble ways that are dramatic but irrelevant. Do not underestimate this tactic, as in the online world this will sway many observers. Do not forget: Correctness is decided only by what is said last, the most loudly, or with greatest repetition.

    Rule 3:
    When it comes to computer news, 70% of Internet rumors are outright fabricated, 20% are inaccurate enough to simply be discarded, and about 10% are based in reality. Grains of salt--become familiar with them.

    Remember: When debating online, everyone else is ALWAYS wrong if they do not agree with you!

    Random Tip o' the Whatever
    You just can't win. If your product offers feature A instead of B, people will moan how A is stupid and it didn't offer B. If your product offers B instead of A, they'll likewise complain and rant about how anyone's retarded cousin could figure out A is what the market wants.

    not sure they could do that this time. they already use 128bit on their mid range cards, they cant get that much lower. if anything they might ONLY make mobile gpus on 28nm to test it out, where 64bit super slow gddr5 wont be missed as much.

    Given that the fab process is going well; what does this mean for Dozer? Does this mean Bulldozer is now going to be made on a 28nm fab later this year?

    Remember, they didn't exactly go with the largest bus possible for the die size. A 28nm shrink of Cypress they are probably aiming for ~200mm2 and have some room to play with some specs while being able to fit a 256bit bus on there.
    28nm Juniper is looking closer to ~100mm2, so they might have to throw some clusters on there to get a 128bit bus.

    The 3870 was the first product on 55nm, was it not?

    3870 was a midrange GPU.

    I believe you're mistaken. 3870 was top end when it was released, and remained there until the 3870 X2 was released.

    The 3870 was never a high end card, it might have been to ATI, but the rest of the enthusiast world did not consider it a high end card. The 8800GT was beating it hands down in every game tested. 8800GT was a $200 card at the time. The 3800 still struggled with AA.

    It was indeed high end in the ATI lineup, replacing the 2900XT. The status of nvidias products at the time is irelevant. The 5870 doesn change the position of the gtx285 in nvidia's lineup, does it? Nor does the i7 on the phenom II line. Each manufacturer has their own product line, and at the time the 3870 was at the top of ATI's.

    as far as i recall yes, it was out very shortly after the 2900

    midrange to what? performance was very close to the 2900, but used half the power. the 4870 did beat it, and was bigger and used more power, but came out months later

    The 3870 came out 6 months after the 2900, and was a refresh of the R600 on 55nm. Then the 4800's came about 6-8 months after that. Ati was on a pretty consistent release cycle when the process technology was ahead of them...now it seems they're ahead of it.

    those wafer shots show a test chip, im pretty sure...
    its not a gpu or cpu, its way to heterogenous for that...

    Technically yes. But it was just a tweaked 65nm process used on the 2600 and 2400 series not a genuine. This is really more of a way of one upping Intel's 65, 45 and 32nm with 55nm, 40nm and 28nm processes than a genuine node change from improved tech. It's marketing really
