 PCI Express 3.0 lanes provide up to 17.5 times higher bandwidth (15.754 GB/s for a ×16 slot) when compared to current external bridges (900 MB/s), rendering the use of a CrossFire bridge unnecessary.Thus, XDMA was selected for greater GPU interconnection bandwidth demands generated by AMD Eyefinity, and more recently by 4K resolution monitors.Bandwidth of the data channel opened by XDMA is fully dynamic, scaling itself together with the demands of the game being played, as well as adapting to advanced user settings such as vertical synchronization (vsync).
