*Note - Since PCI Express is a serial based technology, data can be sent over the bus in two direction. Normal PCI is Parallel, and as such all data goes in one direction around the loop. Each 1x lane in PCI Express can transmit in both directions. In the table the first number is the bandwidth in one direction and the second number is the combined bandwidth in both directions.
