As far as I am aware, yes. The on board controllers are connected to the PCI
bus in the same way, so yes they will have the same performance.

That's not quite true. If the controller is part of the chipset,
chances are it is connected to the rest of the system using some other
type of link (e.g. hypertransport) even if it appears to the OS as a
PCI device.
That said, the bottleneck is usually in the transfer of data to/from
the disk platters, not the system-controller or controller-disk
interfaces.
