* The CPU has more than one means of interconnection depending on the CPU series.
* The CPU's connections can be directed to a PCH chip which can manage a greater number of PCI lanes.
So between the logic board and the CPU and how they work together will set the total number of lanes and then the lanes are distributed to the different slots as well as any dedicated interfaces on the logic board.

George, it’s not that cut & dry! Look at this diagram

As you can see the CPU’s PCI lanes are dedicated for graphics boards in this design.
* The CPU has more than one means of interconnection depending on the CPU series.
* The CPU's connections can be directed to a PCH chip which can manage a greater number of PCI lanes.
So between the logic board and the CPU and how they work together will set the total number of lanes and then the lanes are distributed to the different slots as well as any dedicated interfaces on the logic board.

There is no one answer here:
* The CPU has more than one means of interconnection depending on the CPU series.
* The CPU's connections can be directed to a PCH chip which can manage a greater number of PCI lanes.
So between the logic board and the CPU and how they work together will set the total number of lanes and then the lanes are distributed to the different slots as well as any dedicated interfaces on the logic board.
