What will be the PCH bandwidth on X99 boards?

My ASRock X79 Extreme11 has an integrated PCI-E 8X 3.0 LSI controller. This allows me to get close to 4GB/sec sustained transfer rates. While not terribly important for a gaming PC, it's still nice to have.

How is the PCH connected on the X99 and what is the PCH bandwidth?
 
Most likely the same thing that is being used currently between the PCH and CPU
The DMI 2.0 interface, which is in reality customized PCIe 2.0 x4 connection. At least according to wikipedia

I suppose they could go to pcie 3.0 interface

and the "integrated PCI-E 8X 3.0 LSI controller". you mentioned is a storage controller, which has nothing to do with the PCH to cpu connection

Please, do go on.
 
The CPU got 40 PCIe lanes. Thats where your current LSI controller is connected.

The speed is the same as today for X99:

DMI 3.0 is first coming with Skylake.
