What does DMI link mean?

Hi all,

I saw that Linus referred to a think in his video that I didn't understand. If you see the video about the Core i9 Review, he states that the new x299 chipset has DMI Link x4 3.0 . What in the world is that? Does that mean that is has 4 DMI Link "things" in the chipset? 

Thanks in advance and sorry for the nooby question.

Direct Media Interface. Faster GPU link basically. https://en.wikipedia.org/wiki/Direct_Media_Interface

It is a link between the northbridge and southbridge on the motherboard. Direct Media Interface 

He said that it is 3.0, and that is better then all the other chipsets Intel released. What difference does that make on the overall build?

Has nothing to do with GPU

 

The CPU has 4 PCI-E lanes dedicated to the Chipset to communicate with SATA, USB, Ethernet, Audio devices, and the Chipset is in charge to orchestrate all the communications so that at any given time you can have only 4x PCI-E speed.

Now that I look at it seems pretty funny, we sacrificed tons of USB and SATA devices to have some "PCI-E" lanes on the chipset and called it DMI3.0 and for what?

For M.2 drives I suppose??? They really went on that RAID NVMe devices and Optane bandwagon hard, didn't they?

Thank you. I meant PCI. I almost typed GPU again. Witch I know isn't really accurate but basically gets it across.
