To maximize data transfer capabilities within a system, having the largest lane widths possible
throughout the system is preferred. An ideal system for display wall applications provides PCIe
×
16
links for all add-in cards, maximizing throughput at each communication link.
In the diagram above, assume that each PCI Express link is a
×
8 connection operating at Gen-2
speeds. Each link thus has a total available throughput of 4 GB/s in each direction. Any combination
of input streams being transferred through a given switch that results in the total bandwidth
exceeding 4 GB/s will result in reduced system performance (stuttering playback and reduced frame
rates). Consider the following example:
