PCI express vs AGP

[sigmaseven]

Okay, I am not very familiar with the new pci express market, so I would like some comparisons. Don't have to be exact, but a general performance comparison:

1. What is the agp counterpart of the radeon 300se 128mb?

2. What is the agp counterpart of the nvidia pcx5750 128mb?

2. What is the agp counterpart of the nvidia pcx5750 256mb?

3. What is the agp counterpart of the radeon x600xt 128mb?

2. What is the agp counterpart of the nvidia pcx5900 128mb?

2. What is the agp counterpart of the nvidia pcx5300 128mb?

I can't answer your specific questions of "what is the AGP counterpart to xxx" but you should take a look at this thread:

http://www.computing.net/hardware/wwwboard/forum/27798.html

and the 6th paragraph of this article:

http://www.pantherproducts.co.uk/Articles/Motherboard/PCI_Express.shtml

and this conclusion to an ariticle entitled "PCI Express for Graphics"

http://tech-report.com/etc/2004q1/pciexpress/index.x?pg=3

It is important to remember that current Graphics Card technology and graphics software has not yet developed to the point to where it can fully take advantage even of the AGP 8x bus. That being said, one won't see truely appropriate (appropriate meaning practical) comparisons of AGP and PCI-E cards for a while.

Hey,

Basically on the ATI side, the rough counterpart of the Radeon X600s are Radeon 9600s, the rough counterpart of the Radeon X300 are Radeon 9200s. So the Radeon X600 XT performs more less around where the Radeon 9600 has with the AGP 8X. I'm presuming that the nVidia side would have almost direct equivance - having the FX5900 having a rough performance equivelance to the PCX5900, etc. That's presuming...the ATI side, I'm pretty sure about - read and article I think was at HardOCP or somewhere.

Hope that helps,
