    We have all seen the dual chip Geforce 7800GT graphic card from Asus, and they are even selling a limited amount. Asus is working on putting two ATI chips on one PCB as well and this time it will cover the X1600, X1800 and X1900 GPUs. By having two "dual GPU" graphic cards a "Quad Crossfire" will be possible. To make this even more interesting, this time the user has four monitor connections on the board. Gigabyte will be presenting their version of two ATI GPUs on one PCB in the near future as well.

    My first thought is overkill but at the same time the inner nerd in me is drooling.:)

    yeah, lol :laugh:

    it is overkill... and WAY too expnesive for 90% of the people out there...
    no way i would shell out my hard earned ducats on that, even if i had any to spare...

    but god would i love to get my hands of that type of rig... hehehe...

    Look closer at the PCB...

    The traces DEFINITELY show that each chip only uses 8 lanes.

    So this is not a true dual X16 card (Which won't be out for awhile since X32 slot motherboards do not exist yet). It is simply 2 X8 cards in the end.

    the interesting bit is dual gpus on one board becoming the norm.. sold at a reasonable price.. dual cpus were at first two seperate sockets.. then it moved to dual core or in grfx card comparisons two or more gpus soldered on the same board..

    if dual core cpus can be sold for nearly the same price as single core ones i dont see any reason the same wont apply to gpus.. that way we all benefit not just a few obsessives with more money than sense.. he he

    i like the concept of ultimate performance just not the concept of ultimate money.. for pc gaimg to stay supported by the masses as it has to be for games to be written for the pc.. some kind of money sanity has to be re-introduced.. else what comes next.. four bloody dual gpu cards costing four thousand dollars..

    running a pair of voodoo 2s in sli appeared years ago.. it was just a passing fad.. i can only hope the same applies now.. we move back to the idea of one bloody grfx card even if it does have more than one gpu on it.. he he..

    trog

    ps.. to put it another way.. paying more than double for roughly a %30 performance increase makes no sense (two cards).. paying roughly the same for a %30 performance increase (two gpus one card) makes loads of sense..

    Wow, my card was already outdated when i got it... but it's falling away from the newer cards and planned cards fast :(

    These are gonna be AWSOME!!!!

    Hey, if each core is running on only 8 lines, would it benefit from having the PCIe frequency being overclocked? It doesn't make any difference on my card since it's not bottlenecked there, because it's crap! But it might make a big difference on these.

    ummm do you know what x8 and x16 mean? LOL dude no video cards even benefit from running x16 pci-e over pci-x8 if any 1-2 fps look at benchmarks pci-e bandwidth is not a limiting factor for performance causes no bottlenecks and wont for many years.How the fukkkk do you know its running at x8 pci-e by looking at the pcb do you even know wtf pcb is? lol dude that card is not bottlenecked by anything why talk about sh1t you dont know

    It would not help because PCI-SIG has set limitations on the specifications of the PCI-E Tx and Rx frequency (Transmit and Receive, you can increase the frequency but it is still limited by the Root Complex and Endpoint governing the data transmission).

    Wait for PCI-E Spec 2.0 (x32=5 Gbps instead of x16=2.5 Gbps). There is already some new features in the unfinished spec copy I've read that is sure to interest enthusiasts :)

    I have painted a picture for our trolling/flaming friend:

    [​IMG]


    If you want to know what a PCB is, its a Printed Circuit Board and houses all the passive/active electrical components as well as any chips/controllers/FPGA's etc. You have this thing called a trace ok? It connects all those little guys on the board together (I dont' want to sound too technical else you might get the wrong idea, like you did with my original post).

    Seems like you are very eager to know what x8 and x16 is, well, let the teacher teach you!

    x8 means there are 8 pairs of differential lanes (Let's explain 'differential' the simple way, it means you have a '+' and a '-' terminal, hopefully that wasn't too confusing).

    Just in case you can't put the two and two together, x16 means there are... wait... let me gaze upon the ball of infinite wisdom... YES, it means there are 16 pairs of differential lanes!! By golly!

    Oh, and since there are 2 sides to the PCB (Yes, there's that word again, that means Printed Circuit Board Quake2owns!), you have one side dedicated to the transmission of data and the other side dedicated to the receiving of data! Tada!

    I'll let you figure out on your own as homework as to which side transmits and which side receives (And yes, you can figure it out from looking at the PCB, if you know how the PCI-E spec is of course).


    Class dismissed Mr. Troll !!!

    How the fuk do you know it's running at x8 pci-e which is 2gbs of bandwidth by looking at the pci-e connector? BTW Even if the each core on the chip were talking to each other with pci-e x16 it wouldnt even yield 5 fps more than x8 STFU n00b. pci-ex16=4gbs of x8=2gb tell me exactly you know what the card is running at by looking at the pcb connecting pins anyway dumbass EVEN IF IT WAS TRUE X16 pci-e interface it wouldnt make the cards any faster./

    Why the agression? But if you insist on fighting...

    Correction, it is NOT 2gbps of bandwidth, it is 2GBps (which is much different from what you said, a bit != byte).
    Correction, I never said it's running x8, I said each chip is x8 for a total of 16 (So it is x16).


    (By the way, PCI-E x16 = 2.5 Gbps, not 4 (You are thinking of 4 GBps, which is not the same as 4 Gbps, that is the theoretical max, I'll leave it to you to figure out how to calculate 4 GB/s. Look at the 8 traces leading from each chip to the connector, it cannot be more obvious than that).

    If you got a little confused, it's time to put on your thinking cap because here goes another round. GBps = Gigabytes per second and Gbps = Gigabits per second. There are 8 bits in 1 byte. Encoding overhead is 10 bits for every byte (Research overhead on your own). Take 2.5 Gbps and divide by 10.

    2500 Gbps/10 bits/byte = 250 MBps
    This is actually per lane so since there are 16 of them, then:
    250 MBps x 16 = 4 GBps

    Your wrong, it IS a true x16 PCI-E interface connector because 8+8 = 16.

    Since where did I ever imply anything about fps? All I said was it was dual x8 chips, I never said anything about performance. Read my original unedited reply more carefully.

    How do I know? Pinout for the win:

    By the way... we are a serving member on the board of the PCI-SIG committee.

    So no more trolling.

    agpx8=2048 mbs of bandwidth hows x8 only 2.5gbps? LOL noob anyway you have no clue what you are talking about you can show me all these charts or links you still dont know what the fuk you are talking about case closed x16 pci-e=4gbps! period

    even if the core is talking to the pci-e with x8 it still doesnt hurt performance so why did you even fuking mention it? thats for showing me STUFF YOU HAVE NO CLUE ABOUT!

    How many Bit's are in a How many bits are in a kilobit? how many kilobits is in a kilobyte? how many kilobytes is a megabyte? ok you are pretty clueless

    First-generation PCIe is often quoted to support a data-rate of 250 MB/s in each direction, per lane. This figure is a calculation from the physical signalling-rate (2500 Mbaud) divided by the encoding overhead (10bits/byte.) This means a 16 lane (x16) PCIe card would then be theoretically capable of 250 * 16 = 4000 MB/s in each direction. While this is correct in terms of data bytes, more meaningful calculations will be based on the usable data-payload rate which depends on the profile of the traffic, which is a function of the high-level (software) application and intermediate protocol levels.


    4000megabytes=4gb 2 up 2 down ok

    seems you got alot to learn.

    It seems like everything I said is correct. You seem to think that 4 GBps is the same as saying 4 Gbps.

    4 GBps = 4 Gigabytes per second
    4 Gbps = 4 Gigabits per second


    Interesting how my calculations exactly match your source.

    This thread should be close for your incessant flaming.

    I never said anywhere x8 = 2.5 gbps. I said x16 = 2.5 Gbps (Not the same as 2.5 GBps).

    Can I get a more technical person to come in here and vouch for me and put this flamer down?

    pcie-x16 is 4 gigabytes per second 2 gig down and 2 up 4000 megabytes=4 gigabyte are you dumb?

    My whole argument is you were acting like the each core only using x8 pcie . You made it seem like they are bottlenecked and they arent! a video card running x16 vs x8 shows like 1-2 fps improvement wow big bottleneck pal im not going to reply to such a igonrant person such as yourself.

    its an absolutely worthless setup in my opinion because that is OVERKILL to anygame...and frankly i like having a card a gen or 2 behind that way i have to tweak and mod it up to scratch which is fun :D....


    o and yes it is bottlenecked............................
