RH8 / RH9 and GeForce 2 MX

    Before I upgraded my PC running RedHat 8 I installed a PCI GeForce 2 MX card as I didn't have an AGP slot available.

    Having now upgraded to a new motherboard (AsRock) which is equipped with an AGP slot, would there be much of a performance gain in moving to an AGP based card?

    AGPx4 bandwidth - 1,017 MB/s
    PCI Bandwidth - 127.2 MB/s

    Just a little difference! ;)

    Depends on the workload. You might not feel the difference at all, particularly if you're only doing desktop work. If you're having problems playing DVDs full screen an upgrade might be in order - that's probably the most bandwidth intensive application. Most other applications seek to minimize transfers across the bus, whether it's PCI or AGP, and cache data on the card.

    Yeah I have the same card.

    I have to say though, if you look at the frame per second output of glxgears.... even that PCI card puts AGPs from just about 2 1/2 to 3 years ago... 'to shame'.


    So for example the 'integrated' AGP in my Dell Dimension 400... is sad in comparison to my Nvidia, even though the Nvidia is a PCI card, as opposed to an AGP one[1]


    [1]AGP runs over the PCI bus though.

    Don't all AGP implementations go straight to the northbridge over a link independent of the PCI bus?

    True.

    But, certainly, the Nvidia chip, despite being on a PCI bus, outperforms the (integrated) ATI which came with the Dell.

    I'm not sure if the integrated AGP, actually runs on an AGP bus (though I do think it has it's own ram), but, I have a vagure impression in my head, that I get better fps from the PCI Nvidia then I do from the Voodoo 4 in my main box, and I certainly get better performance then from the integrated ATI.

    That's all to do with having faster and more onboard ram, as well as a newer better chip, then the Voodoo 4500 or the ATI.

    In fact, I might be wrong, but I seem to remember (hearing in a random place) that some Nvidia chips had become more complex (ie having more transistors) then a Pentium 4.

    It's a monster of a chip with 106 million transistors, which makes it more complex than a Pentium 4 processor.
