Sli with the new RTX Cards

[telboy121]

Any one have any thoughts on sli for the new cards?
looks like nvidia are backing sli again! perhaps with the new link the cards
will perform better than the increase on older gen cards?


Please continue all discussion of the RTX cards in the mega thread until there are actual reviews or shipping hardware. Thanks!

I hope so. We need someone to really start jump starting M-GPU again with better scaling and support.

You have to buy a 2080 or 2080ti, and the bridge connector is expensive.

With that much bandwdith, two GPUs looks like one GPU

Aim is to make as many GPUs as possible in a single system with a single GPU driver process

It does show a possible future MultiChip GPU & potential for high Multi GPU scaling using NVLink.

For compute this isn't a big deal making this workable, and this is what all those slides are about (and all the MCM GPU papers as well).

I see no sign that anything is changing on the gaming GPU front. I bet you still need individual developer support for each game, which really pushes SLI to a extreme fringe.
