    AGP & PCI-E 16X Motherboard

    Will these be produced for AMD64 based systems. Via has the PT880 Pro for Intel based motherboard soI was just wondering if there was any likely hood of a similar thing for AMD systems? Either from Nvidia or Via.

    NForce 4 and VIA K8T890 Pro are both PCI-E. Both have been available for a bit.

    Yes, but will they be bringing chipsets out that support both the PCI-E busAND the AGP bus.

    I doubt they'll be releasing AGP / PCI Express x16 motherboards, as with 2 x16 slots for SLI in the near future, there just won't be enough space.

    they will not be releasing these.

    Originally i was hoping for one too, it would be great for the gradual upgrader like myself, but sadly all of the main manufacturers said there would definately not be a board like this.

    Intel have quite a few with both slots and its not like its hard to put an AGP slot on, i mean it just piggy-backs on the PCI bus doesnt it? and all boards have at least 2 PCI (non-PCI-E) slots so the bus still exists.

    or have i got the theory wrong here?

    but short answer - No AMD mobo's with both AGP and PCI-E will be coming out.

    The closest to both of them on the same motherboard, was when I read about a guy who thought he had both, but it turned out he had misidentified his ISA bus......

    Now why would anybody want to do that? It would be difficult (if not impossible) and costly to do this properly so that the limitations of AGP do not affect the PCI-E functionality. There is no market for such a thing although I'm sure some MDB makers have already come up with it as a gimmick to try and sell more motherboards to P4 users.

    [DW]Cougho;

    Gradual upgrades are not only more costly in the end but also compromise performance. It's best to save up your money and upgrade all at once.

    Think of the decrease in performance with the AGP and PCI Express both putting strain on the processor. Plus, imagine the difficulty of a BIOS managing 2 GPUs? It'd have to be a one on, one off situation. Its just not feasable.

    If they can do it on the P4 then why not on the AMD platform?

    I don't think it's a question of feasibility, it's more a question of marketability. It would certainly make a system more upgradeable.

    Well, in the short term yes its upgradability will be good. But give it a year, and you've got a system which for one can't support SLI, and has what is now I guess a 'legacy' AGP bus, which would put unnecessay strain on an otherwise capable system. For that reason, I reckon most people wouldn't touch it with a barge pole.....

    Oh, and also... Think of the heat that thing would give off! It'd be like a Prescott on a bad day.

    Why? An unused PCI slot doesn't put 'unnecessary strain' on a system.

    However, to be fair boards supporting dual RAM types have never been up to much.

    Well, I daresay the architecture of the motherboard would mean part of the processing power etc would be automatically allocated to the AGP port?

    In reply to some of the above posts:

    if you were somebody like myself that wanted such a motherboard you wouldn’t want SLI anyway. And you wouldn’t use PCI-E and AGP together. That just wouldn’t make sense. Kez mentioned the all important words "More upgradeable". Which is what im interested in. As my sig says i have an AGP card, when the time comes to change this card i would need to change my motherboard since everything will be PCI-E. This is why im enquiring about such motherboards because they are coming out for Intel platforms.

    Well, unfortunately such a motherboard doesn't exist. Marketability and upgradability issues aside, I think it would be too difficult to design for real life use. I mean, how would you enable PCX x16, and disable the x8 AGP in turn? It'd need a whole new architecture too, to take into account the new bus' input. Plus, the BIOS would be much more complex.....


    ALSO, I can envisage some kind of compatability problems when in Windows?

    Just because something can be done doesn't necessarily mean that it should be.

    It's not a matter of whether or not it can be done (obviously they're doing it on P4 systems) but how much it would cost to pull it off in such a way that the advantages of PCI-E could be realized while maintaining AGP functionality. That is NOT achieved on the P4 hybrid boards. PCI-E on those boards suffer as a result.

    Dorza,

    And I suppose you think a motherboard that supports both P4 and AMD 64 CPUs is a good idea?

    Sometime things don't exist for good reason.

    No i don't. Where did you get that notion from . However if you’re able to remember the early days of modern computing you should know that motherboards did support both AMD and Intel CPUs. Prahaps not together but you could interchange between them. In fact some motherboards even supported Cyrix CPUs as well. It has been done in the past.
