[SOLVED] NVLink and the new RTX cards.

[BigLouis1971]

I heard that the new NVLink bridge technology makes possible memory scaling. Is that true for the new generation of cards? Specifically, will I get 16GB of memory from two RTX 2080 cards running on NVLink SLI?

Short answer: Yes, but not for gaming unless the game developers specifically do it. Which has been a feature of DX12 for a while anyway.

Long answer: Puget Systems did some testing: https://www.pugetsystems.com/labs/articles/NVLink-on-NVIDIA-GeForce-RTX-2080-2080-Ti-in-Windows-10-1253/

I would not expect this though. Targeting the .1% of people that would have SLI or NVLink SLI is just not worth it outside of a tech demo.
