AGP 1x/2x/4x/Pro ?

[cbwolf]

What kind of difference in rendering speed could you expect between the different speed AGP interfaces?

I have an AGP 1x slot on my motherboard, and i wanna know if it would be worth my money getting something like a GF2 MX.

Actually... I don't think an MX will run on a 1x AGP slot.

I think you need a 2x AGP slot minimum. =(

I think AGP cards run regardless of AGP 1x/2x/4x...

I'm pretty sure that AGP cards are backwards compatible. From what I hear the gain from 2X to 4X is negligible. It would be hard to bench it though because boards with 2X usually have slower surrounding technologies impacting the AGP bus.

AGP is backwards compatable as long as the voltages are both the same (IE: voodoo5 and p4 boards).

I actually had an Intel SE440BX, a motherboard with 1x AGP.

My Geforce256 DDR (Creative Annihilator Pro) would not work in it, while my Riva TNT2 Ultra would. AGP 4X with Fast Writes: Yes (Annihilator Pro) AGP 2X with sideband support (Rivan TNT2 Ultra). The box said the Annihilator Pro was backwards comapatable w/ 2x AGP while the TNT2 Ultra was backwards compatable down to 1x.

I also had an Asus P3B-F and Asus P2B-D which the Annihilator Pro WOULD work in. Are these 1x AGP slots too? I've always thought so, but the Asus site describes them as AGP 2.0 compliant slots. Most Video cards made today also require AGP 2.0 compatability. Is there more than one standard for 1x AGP slots? so AGP 2.0 does not equal AGP 2X?

EDIT: just read Compuguru's reply... could it have been a voltage issue?

The difference between 2x and 4x is almost nothing these days (games don't relly even push agp2x). AGP Pro, AGP50, or AGP4x50....is just AGP4x with 50w (or 110w) to available to the AGP bus instead of the regular 25w.
