NVIDIA GeForce RTX 2080 Ti NVLink SLI Scaling Explored
GeForce RTX 2080Ti NVLink SLI - Our Summary: NVLink SLI Vs Previous Gen
Performance Summary: NVIDIA's new NVLink-based SLI multi-GPU technology seems to have lots of potential, though we are still in the early phases and the technology isn't being fully utilized with current applications. In reality, multi-card scaling has been a point of contention for many enthusiast gamers, as many love their multi-card builds, even though performance scaling upside has diminished recently, both in terms of performance and support from developers. Enthusiasts have felt the sting of diminishing returns for SLI, and Crossfire as well for that matter, but it's exciting to see a breath of new life given to multi-card configurations. That performance comes at a cost and right now it's steep with two RTX 2080Tis coming in at $1200/ea and an NVLink bridge at roughly $70 - 90.00 (less obviously, if you go with RTX 2080s).
NVIDIA has given enthusiasts a reason to be excited about SLI with NVLink, though again, it's a more forward-looking view. As games come out utilizing DLSS and DXR/RTX, we should really start to see what the RTX/NVLink marriage can do. As of right now, this is the pregame show, but we look forward to see how the performance evolves over time and even how it scales on other platforms.
