Nvidia NVLink is the new bridge that will come with the new Nvidia RTX graphics cards and while the Nvidia NVLink offers higher bandwidth as compared to traditional SLI, you should not expect too much when it comes to gaming performance. Nvidia’s technical marketing director, Tom Petersen talked about Nvidia NVLink performance gains.
He mentioned that the Nvidia NVLink performance difference will be there in a few games but the difference is going to be small. The following is what he had to say in this regard:
Now it is true that we might be able to do slightly better on some games, maybe reducing a little bit of the frame time because we have a bigger, badder link, but I think it’s going to be small.
The Nvidia NVLink is not about providing gaming performance at the moment. It is about not having to change the PCB of the Quadro graphics cards. But that does not mean that it does not open doors to a major boost in performance in the future. It is something that Nvidia could work on for the future. Petersen further went on to mention the following:
Think of the bridge more as we want to lay a foundation for the future and that requires us to move the infrastructure along. So we already have a multi-GPU application called SLI, why don’t we just make that work on a really high-bandwidth bridge bus? And once that works, and we get our bridges deployed, and people understanding that hey, this is a 100GB/s bridge, then game developers will see that.
Nvidia NVLink is a peer to peer interface that offers much higher bandwidth as compared to SLI, so that is something that game developers can take advantage of. We still have to wait and see what kind of performance we get in games and when the RTX graphics cards are released we will be able to enlighten you regarding the matter so stay tuned for that.
