Indeed, PCIe is serial. The amazing advancements in LVD signaling and
high-speed PCB design have given us a lot of interesting new
capabilities. The PCI bus evolved FROM parallel TO serial to gain more
speed, whoda thunk it? ;) It turned out that, in the end, skew along
parallel buses became a bigger problem than pushing the speeds into the
GHz range.
