PCI-e x1/x4/x8/x16 difference?

Hello again! long time since i posted anything.. :crazy:

But im just check what the difference for the different PCI-e modules has as influence at the computing, i know that there are lower speeds at the ports, but i dont really know if it has any performance weaknesses in computing.

For low-bandwidth tasks like password cracking on GPU's with proper implementation (i.e. async transfers) they are absolutely equal.
In the bad case, there is only a slight difference.
