AMD help

I know that Intell chipsets work like this.

The Northbrige is connected directly to the CPU and the speed of the Data going to the Northbrige from the CPU is called the FrontSideBUS.

And the Main Memory is directly connected to the Northbrige to.

And the Northbrige is connected to the Southbrige directly.

And everything els is connected to the Southbrige.

I get this and how it all works.

Now I do know that the AMD CPU is connected directly to Main Memory by it's own Memory BUSS because the AMD CPU has a Built in memory Controlor.

So the Memory does not have to go through the Northbrige to get to the CPU.

OK I get this.

And I know everything else is on what they call a Hypertransport BUS.

What I want to know is is the AGP and PCI Express still connected to the Northbridge and is the Northbridge still connected to the Southbrige??

And is everything else connected to the Southbridge??????
I keep reading a lot on the Internet and I saw a lot of Specs so don't give me a link Please.
Just tell me in your words.
Thanks

Yes the PCIe lanes are run off the Northbridge and the Northbridge is connected to the Southbridge. The CPU has a direct link to the southbridge starting with the 700 series.
 
Thanks but

So Intell CPUs have to go through the Northbrige to get to the Main Memory and the AMD CPUs go directly to the Main Memory because they have the Memory Controler built in.

Do I have this right??
 
Intels i7/5 series, they have a onboard memory controller. AMD has had it since the release of the Athlon 64.
 
OK but

So let me see if I get this.

AMDs go directly to Main Memory not to the Northbrige first.

So why does AMDs still need a Northbrige chip is it the only way the AMD can talk to the Southbrige?
