Stupid Question 5

Hey, so, why is it that the new RTX cards can only go for 2-way SLI instead of 3 or 4 way?

Nvidia dropped support for 3 and 4 way SLI when Pascal launched, and it was on its way out when Maxwell launched.

Yeah, but why? Wouldn't 4-way bring out max performance potential for large scale builds?

3 way sli and 4 way sli often brought bad performance even when compared to a single card setup.

So... Nowadays 4 way SLI is normal reserved to workstation cards like Quadro?

Yes because workstation tasks scale well beyond 2 cards while games generally get decreasing performance or simply don't work.

They didn't scale well enough to merit needing. In some cases, due to how badly 4-way SLI scaled, it would result in lower performance.

Essentially. Quadros are a bit different, in that they use NVLink rather than SLI.

I see. Well, thank you!

Simply because nobody is developing games in a way that makes any sense having a 3rd or 4th card.

Quadro cards on workstations will most of the time be additional compute hardware and not graphical rasterization like happens in games.

 

The workload is simply different.

So they would essentially be backups for the CPU load?
