North Bridge contains memory controller and AGP/PCI-e port and connects to CPU and south bridge.
South Bridge is controller for all other integrated I/O

and why does the via and sis have degraded performance when it comes to intel cpu mobo's VS pure intel mobo's?

Intel North Bridge has superior Memory Controller
