AGP 4x vs AGP 8x

[Serch]

Hi. I have been told that with mid-class video card the difference between AGP 4X and 8x is minimal.

Example:

Running an FX5500 designed for AGP 8X, in a mobo with 8x has only some 5% better performance than using the same card in a mobo supporting 4X.

Is it true?

Im pretty sure it is but I am not sure.

it's probably even less than 5%

with a fx5500, it's less. with a high class say a x850xt, the difference is olny like 5-10% and that x850xt is about 11ty billion(actually about 6x or so) faster than a fx5500 which is very lower end.

Speaking for myself, I've found the difference to be much smaller than %5. In some cases, the results were either the same or (for whatever reason) faster running at 4x AGP, but differences were so miniscule, they're irrelevant.

My second fastest machine (see box #2) uses a x800xt PE with a VIA K8T800 board. This particular Soltek MB has a problem running any card at 8x AGP with any amount of stability so I am forced to keep it a 4x AGP. Benchmarks are virtually identical from 8x to 4x.

no difference. However 7800GTX's would have used a theoretical AGP 6x which was probably the main reason it was never released for AGP.

why 6x agp?
also 7800gs is confirmed for agp.

Thanks for all the help!

there is 0 difference tomshardware had a test on this.

The difference is negligible. The only thing you should worry about is the CPU bottlenecking the GPU.

meh, yea wasn't it for streaming textures from system memory? but thats so slow its useless anyways so it doesn't matter.

I have 2 Matrox Parhelia cards. One, 4X ; the other 8X.
I've found the 8X capable of running 3 monitors at higher resolutions. Maybe because it has 256MB compared to the 4X's, 128MB. I like the feel of the 8X and it seems my video seems sharper to view, but what do I know. It could be my imagination.....
