The PCI Express x16 graphics interface (also called PCIe x16) offers increased bandwidth and scalability over the previous AGP8X generation. PCI Express x16 allows up to 4 GB/s of peak bandwidth per direction, and up to 8 GB/s concurrent bandwidth. PCI-Express x16 is used by the Intel 915 and 925 and other chipsets which support PCI-Express. See also PCI Express.

PCIe Ramps Up : Seven PCI Express Graphics Cards Compared PCI Express X16 slots have peak bandwidth levels of 4.0 GB/s (up to 8.0 GB/s bi-directional), compared to 2.1 GB/s of AGP 8x. While the extra bandwidth is always nice to have, even today's high-end graphics cards don't make use of the 2.0 GB/s which AGP 8x offers, so the extra bandwidth PCIe x16 offers is generally regarded as a feature which "future-proofs" the graphics card standard for the next few years.
