AGP and AGP Pro?

[Sirrush]

Okay, So I have a pretty old mobo (Asus A7V333) With an AGP Pro slot for my graphics card, this however totally confuses me and after asking around for a bit someone told me that I can in fact use an AGP card in an AGP Pro slot.

Can anyone confirm this?

Oh and is AGP 8x also compatible with AGP Pro?

Thanks,

That motherboard supports AGP x4, so it will work with AGP x8 cards, they will just run @ x4 bus.... with no loss in performance

I am not sure about that no loss in performance surely slowing down the speed at which the card receives information from all other components can't allow the same performance levels. You may want to think about updating your system rather then just buying a new graphics card as agp is the old standard pci-expressx16 is the new standard for cards and I am guessing you have also got ddr ram which is also slower and outdated then ddr2

I am sure about it - 4x is more than enough for practically any card out there, you won't see any difference running an 8x card in a 4x slot compared to an 8x slot.

You could have a gazzilion mhz connection to the rest of the system, but if you're still waiting for either information to be generated and set to the GPU, or the frame to be rendered and buffer cleared to accept more information, it's wasted

Well it would depend on the card.
I'm sure you would notice the differnce on a 7950GT ( Yes they do exist ) But for the GeForce4MX in Sirrush's specs, No differnce.

it would be nice to have a benchmark of 4x vs 8x if the chipset/cpu/memory/etc was exactly the same.. oh wait, i found one here

negligible difference

Well, actually, I want to upgrade my GPU so that's why I asked it

And thanks everyone for the answers, now I finally know what to look for

Edit:
Ok, Ive found a graphics card, but just to be on the safe side, this is what it says:

Club3D GeForce 7600GT 256MB, GDDR3, AGP, DVI/Tv-Out, Retail

^Works on the AGP Pro just like 8x works on Pro?

Don't know whether it's trustworthy, but Tom's Hardware did such a test with a 8800GTX I suppose, scaling from PCI-e x16 to x1, and it showed that the performance decreased even when lowered only to x8.

[saltynay]

not relevant pci-express is the different type of interface the 8800GTX does not come on agp because it is a highly powerful card

We're not talking about PCI-e here since my mobo isn't PCI-e, but AGP

And a 8800GTX would be way out my budget anyways

Fil your boots, that should work fine, iirc, theyre different voltages, but it should auto sense. Also, to bput the record straight, i get exactly the same benchmark (within margin of error) on my machine at 2x AGP as i do at 8
4x is 1GB/s, whereas 8x is 2GB/s, if anyone thinks there machine can go through 2 GB/s of graphics data every second then theyre dead wrong
