    PCI-E x16 is 5% longer than PCI. PCI is about 3.12" long, so PCI-E x16 is about 3.28" long. Total length (on-screen) of that card is 4.25", with PCI-E x16 at 1.5". The PCB is definitely 9.5" long.

    21.5 cm or 8.5" so you will be fine Manicdan.

    Actually I think 9.5" might be correct like bobsama is stating, I think it's longer than 8.5", it's just my measurement of the connector that might be off using a measurement tape (which in fact is a bit worn so the tip moves a little) so it could be closer to 1.4cm rather than 1.3cm, I need a very exact length of it or 16.5 times that will get you a very different result. At least we know it's the length of 16½ power connectors.

    So does any1 know the exact dimension of a 6-pin power connector?

    9.5 sounds right, basically as long as a motherboard (9.6")

    Yeah that is remarkable to be honest. ~2x faster with a smaller die size. Zzz

    PCIe power connectors on the side of the AMD card. And i thought i'll never see anything like this.

    Here is a pic of PCI-E connector


    Its 14mm
    And 14x16.5= 231mm which is 9.09 inches

    but thats a flush measurement, add in 1-2mm for the spacing gap and were up to 9.5" again

    Total with the shroud seems to be about 9.6-9.7"--basically a perfect fit for 9.6" wide ATX boards.

    Over at B3d, they calculated out the SP's are likely to be 800/960 for Pro/XT Barts respectively... impressive if 800/960 can get the card to close to the 1440/1600 Cypress parts. I can't even imagine what Cayman can do..

    I think the reason why the power section is at the back is for cooling reasons.
    E7200 @ 3.4 ; 7870 GHz 2 GB
    Intel's atom is a terrible chip.

    Yep, exactly what I was thinking. Blow the hot air out first from the GPU, then PWM.

    Makes sense since the PWM did get very hot in 58xx cards.

    I get the impression that Cypress wasn't as efficient as I originally thought. It looks like they've improved efficiency quiet a bit with the Barts.

    well, think about the 850 mhz 800 Sps 4890, it was better than 5830 even at just 800 sps. I assume that if they tweaked the architecture, they would try the same level of efficiency.

    A 960 shaders Barts at 900 mhz with that efficiency would be really nice

    I get the impression that if the performance info is right about 6870 it may beat the 5870 in certain "limited" situations. But I still like to know if there is some sort of HW implementation for MLAA? Anyone know?

    As far as the rumors go it sounds like people think the 6870 will be roughly as fast as the 5870. And according to the Holland prices it will be the same price. So, basically we're looking at same performance for the same price. XD

    I can't wait to get real figures.
