You go from (this is off the top of my head) 2.2 to 2.8GB/s I think. Anyways, you won't notice a difference is what it comes down to. |

AGP4X is only capable of transferring data at a maximum bandwidth of 1.06GB/s. Compared with all the existing buses in the system, it is rather low and 3D performance would bottleneck at the AGP port. There's really no point in having kickass technology like HyperTransport if the AGP is limiting data transfers at 266MHz (4 x 66MHz). 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.

To take advantage of the extra bandwidth, you need both a card and a board that supports agp 3.0 and are 8x comp. That quote above is also a little old. With AGP 3.0 and the new mobos and cards out, 8x goes up to almost 3GB/s
4x still maxes around 1GB/s.
