NVIDIA GeForce RTX 2080 Ti NVLink SLI Scaling Explored

GeForce RTX 2080Ti NVLink SLI - Tomb Raider And Strange Brigade

Rise of the Tomb Raider is a sequel to the 2013 reboot of the Tomb Raider franchise, which takes protagonist Lara Croft back to her explorative “tomb raiding” roots in a deep origin story. The game, however, was updated and enhanced with new gameplay and combat mechanics. The engine was updated as well, and offers DX12 support, along with some stunning visuals. The benchmark outputs results from a number of maps; we’re reporting numbers from the “Geothermal Valley” here, along with the average score of all the maps. The game’s maximum “Very High” graphics preset was used, and all graphics-related options were enabled as well.

Our Geothermal Valley results are interesting as the HB SLI pair of GTX 1080 Tis pull a clear scaling win (though not overall) over the NVLink pair of GeForce RTX 2080 Ti's at both resolutions. Just for record, 1440p shows GTX SLI at a 32.88% gain versus RTX NVLink at 19.38%, while 4K shows GTX SLI at a 94.55% gain veresus RTX NVLink pulling 81.56%.



The overall results in Tomb Raider show at 1440p that the RTX cards are much closer albeit still behind the GTX counterparts in terms of scaling. The difference is only 3.3% approximately, whereas at 4K the result only closes somewhat, though still over an 11% deficit.  Perhaps it's time to start testing 8K panels in an effort to show how these cards can really stretch their legs.

DirectX 12 (Or Vulcan!) Benchmarks
Strange Brigade is a third-person action game set in Egypt in the 1930s that takes gamers on an various adventures to explore ruins, solve puzzles, and uncover valuable treasures, while also blasting through an array of un-dead enemies. This game has both DirectX and Vulcan code paths and makes use of Asynchronous Compute as well. We tested Strange Bridge with its Ultra graphics preset with A-Sync compute enabled at a couple of resolutions.

Strange brigade once again bogs down just like Tomb Raider. This time the deficit at 1440p is only a little over 7% but its still in favor of GTX 1080 Ti HB SLI scaling. At 4K the deficit also is slightly over 7% in favor of  GTX SLI. It is worth noting though that the scaling being at over 85% is great since so many new games these days do not really work well with multi card, so its nice to see DX12 doing its job in a few instances.



Render times once again relate the inverse of what we saw with framerate as its simply the measure of how long it takes to draw a frame. This would be a good time to mention that while the standardized FPS numbers show a better scaling in favor of legacy GTX 1080 Ti HB SLI here, the overall performance obviously is better for dual GeForce RTX cards and it shows more prominently perhaps, in these lower frametimes.
