I know that AMD uses an onboard memory controller in place of an off-CPU Northbridge. I also know that the Northbridge connects to the Southbridge, RAM, and Video Card.
What I dont understand is how an AMD system connects to the Video Card and Southbridge. Is there still a Northbridge that connects the Southbridge and Video Card to the CPU, while the on-die memory controller handles only the RAM?
This is just out of curiosity, by the way.
Yes, I did search Google and TF already
