quite simply, more graphics data can be transferred through an agp 8x port rather than an agp 4x port

high end graphics cards need an 8x agp enable motherboard to really maximise their use

it is possible to use an agp 8x graphics card on a motherboard with an agp 4x agp slot, however, you will not be getting the full graphical power of the card

i think the difference in rendering speed isn't that great, but it's primarily the swapping of texture files between the video card's RAM and the motherboard's RAM which is faster. if your graphics card has a lot of RAM (128mb, 256mb), it makes the higher AGP speed less necessary because it can just store more textures on the card without having to swap into the motherboard's RAM.

nevertheless, 4x is better than 2x, and 8x is better than 4x. the difference in performance is revealed when a game uses more texture data than can fit on the video card's RAM.

PCI Express? never heard of it...what kind of bus speed will it run?

For instance, today&#39;s graphics cards are linked via Accelerated Graphics Ports (AGP) and at AGP 8x rates, which can transfer data at around 2 GB/second. By comparison, with 16 lanes of PCI Express (each lane transfers data serially at 2.5 Gb/second), 4GB/second can be transferred each way

I think you mean 40Gb/second (16 times 2.5)

Edit:
My apologies, you do mean 4Gb/s.
Well, that&#39;s intel for you, about as efficient as the pentium chip.
