PCI Express is a two-way, serial connection that carries data in packets along two pairs of point-to-point data lanes, compared to the single parallel data bus of traditional PCI that routes data at a set rate.
PCI Express (PCIe) is a serial bus, with each lane sending digital signals as a 2-pin differential signal. To transmit the same amount of data, the serial bus needs to run at a much higher clock rate, but synchronizing that single signal is easier than making sure all 32 parallel signals arrive at exactly the same time, and the differential signal is more resilient to electrical noise.
