Just got word that Hardwarezone.com have posted a comparison that investigates the performance gains to be found in AGP8X compared to AGP4X! Here's a byte from their article.
Now that AGP bandwidth is doubled to 8X, the clock frequency will increase to 533MHz which means that it will transfer at about 2.1GB/s. This increase in bandwidth will directly help to improve the overall performance of the graphics subsystem. By how much? We'll investigate this further in this article. Currently, there are not many chipsets that support this new AGP 3.0 interface. One of the first manufacturer to demonstrate AGP8X was SiS with their SiS648 chipset along with the all-new Xabre400 GPU. Other chipsets which will have support for AGP8X transfers include NVIDIA's nForce2 and VIA's P4X333/P4X400 and KT400. AGP4X vs. AGP8X
