Difference between 4-way SLI and Quad-GPU SLI?

[AstroBenny]

I was looking through Asus' motherboards and I see that you have the option to select 4-way SLI and Quad-GPU SLI...

I though they were the same thing..No?

I'm confused.

quad gpu probably refers to using two dual gpu cards such as 7990 or gtx 690

This is correct

Just to add Make sure you graphics cards are compatible with  2 way or 4 way SLI because some model graphics cards don't SLI or Crossfire.

I'd presume that a dual-GPU card would support SLI or CF, even if only 2-way so the two on-board GPUs would work.

 

But, what about when installing said card on a board that doesn't support SLI/CF, like an H110 chipset board?  Would both GPUs work as normal, or would only 1 of the GPUs work?

 

Also if someone was doing a "multi-users, 1 PC" build, for example using the Asus Z10PE-D8 WS board and 2x Xeon E5-2699 v4s, would it be possible to have 14 simultaneous users on that 1 PC?  (My theory is that all 7 slots would be populated with watercooled 6990s, GTX 690s or Radeon Pro Duos.  Each user would get their own GPU, with 2 users being assigned to a single card.)  *braces for shots fired at me for giving Linus more ideas at getting crazier with those builds...*

 

Another idea would be for Linus to do a video comparison ... which is better bang for the buck when you need to set up multiple users?  Build one kick-gluteusmaximus PC like that and do 14 users 1 PC, or build 14 PCs whose performance and specs is equivalent to the VMs running on the 1st scenario?  (One example scenario I was thinking of for something like this was at a public library or internet terminal.)
