Noob question: what do I do with my Thunderbolt 3 PCIe Network and IO Card?

I bought a the most powerful Dell computer I could this month to use for video editing. 

It came with a Thunderbolt 3 PCIe Network and IO Card. Now that the machine is here, I realize I have absolutely no idea what this card is supposed to do, other than a vague notion it could speed collaboration over a network.. It came with no documentation. It does not have a standard ethernet port (though I'm sure there's some new standard).

Can anyone offer a little guidance? Thanks

Please post model number and specs of your Dell computer and Thunderbolt 3 card. Photos of such setup would be useful too.

The Dell is an XPS 8930 Tower, w/32gb RAM and an 9th gen I9 Intel CPU.

The Thunderbolt card is only identified as a 3PCIe Network and IO card. It's the card in the bottom slot, with three ports. I don't know anything about the card in the middle slot. The card in the top slot is an NVIDIA(R) GeForce(R) GTX 1080 with 8GB GDDR5X Graphics Memory.

Actually identified as "Thunderbolt 3 PCIe Network and IO Card". I think it's just a Thunderbolt 3 add-in card. In that case, "Network" means you can make a Thunderbolt network with another computer that also has Thunderbolt; and "IO" means you can connect any Thunderbolt 3 peripherals to it.

Is that a DisplayPort input or DisplayPort output? It can't be an output unless there are inputs inside. Post photos of the card itself. Does it use Alpine Ridge or Titan Ridge? Is it PCIe 3.0 x4? Is there a Thunderbolt header cable connecting the card to the motherboard? It appears to be low-profile compatible so Dell can use it in low profile desktops just be switching the backplate.

It’s display port in. Dell ships a barely 10-12 in dp to dp cable. But not info. Unsure what I would DisplayPort into that

Like every other Thunderbolt 3 add-in card (such as the GC-ALPINE RIDGE or the GC-TITAN RIDGE), you would connect the DisplayPort output of your graphics card to the DisplayPort input of the Dell Thunderbolt 3 PCIe Network and IO Card so that you can connect a Thunderbolt display or Thunderbolt display adapter or Thunderbolt dock with HDMI or DisplayPort output or USB-C display or USB-C dock with DisplayPort output to a Thunderbolt 3 port.

Since the Dell card has only one DisplayPort input, it cannot support 5K displays (dual link SST DisplayPort 1.2) or more than one 4K display. If it used a Titan Ridge controller, then it could support a DisplayPort 1.4 5K display.

I’m not really seeing the benefit of this card if it just for adding displays via thunderbolt.  And I would assume some performance loss with the steps it has to take. 

Is this for someone that just needs tons of external monitors? And the higher end graphics have quite a few out. And can daisy chain monitors... guess I’m not seeing the possibility’s

There is no performance loss for the display. The signal that comes out of the graphics card is the signal that is transmitted to the display. Maybe there's a few pixels of latency. A few pixels out of 8 million is nothing.

Thunderbolt 3 devices (hard drives or whatever) can transfer data at up to 2750 MB/s. USB 3.1 gen 2 devices (hard drives or whatever) can do 900 MB/s. The Dell card supports both. It supports USB-C docks and USB hubs and USB devices as well as Thunderbolt devices.

Thunderbolt displays have USB ports usually up to USB 3.0 speeds. The original Apple Thunderbolt Display (which was a Thunderbolt 1 device) had 3 USB 2.0 ports, FireWire 800, Gigabit Ethernet, HD camera, and speakers, which all could be used with just a single Thunderbolt cable connection to the computer.

Laptops can be charged by the Thunderbolt dock or display that they are connected to.

Thunderbolt networking can be used between two Thunderbolt capable computers providing file transfer speeds greater than gigabit ethernet - up to 1.3 GB/s for a Thunderbolt 3 network which I think is greater than 10 Gigabit Ethernet (between 400 and 800 MB/s). You can add 10 GbE to your computer by using a Thunderbolt to 10 GbE adapter.

If you run out of PCIe slots, you can connect a Thunderbolt to PCIe expansion box.
