Intel VS. AMD : PCI EXPRESS VS AGP & PCI
The PCI-Express bus is the next major evolution in PC bus technology. It improves on the PCI bus by providing dedicated serial interfaces running at full-duplex (simultaneous two-way data transfers) between each PCI-Express device. Each “lane” of the PCI-Express bus can transfer 500MB per second in both directions verses the 132MB per second of the entire PCI bus. AGP 8X provides up to 2112MB per second but by combining PCI-Express lanes in powers of two (x1, x2, x4, x8, x16), PCI-Express can transfer up to 8000MB per second! That's a lot of bandwidth and should hopefully hold us off for the next ten years. A PCI-Express x16 slot can be found in the place of the AGP slot on the ChainTech board below (slot furthest to the right) and the two tan PCI slots can be found to the left of the PCI-E slot.
