NVIDIA GeForce RTX 3080 Ti Linux Performance

Across the wide range of Linux benchmarks conducted, the RTX 3080 Ti power consumption was comparable to that of the RTX 3090 and much higher than the likes of the Radeon RX 6800 XT.

When taking the geometric mean of all these Linux benchmark results, the RTX 3080 Ti came in right between the RTX 3080 and RTX 3090. The RTX 3080 Ti in these tests on Linux were about 34% faster than the prior generation RTX 2080 Ti or 2.84x the speed of the GTX 1080 if still running a card two generations old. The GeForce RTX 3080 Ti in these OpenGL/Vulkan benchmarks came out to being 21% faster than the Radeon RX 6800 XT.

Those wanting to see even more Linux benchmarks of the GeForce RTX 3080 Ti can see this OpenBenchmarking.org result file. From there you can also see various performance-per-Watt metrics based on real-time power data collected as well as generating your own performance-per-dollar metrics based on local/available pricing.

I did also run a number of Vulkan ray-tracing benchmarks with the limited amount of games (Quake II RTX) and demos/benchmarks out there for Linux at the moment. Besides the limited Vulkan ray-tracing usage on Linux at the moment, the comparison there is less interesting for cross-vendor testing because NVIDIA is the really only viable vendor for Vulkan ray-tracing on Linux at the moment. AMD did recently release their Vulkan ray-tracing driver for Linux which at the moment is just bound to the Radeon Software for Linux packaged driver and not yet AMDVLK while the Mesa developers are still working on ray-tracing support for the more popular RADV driver. So I did run some tests with the Radeon Software packaged driver with their initial Vulkan ray-tracing support but it with the Radeon RX 6000 series is trailing NVIDIA in most tests.

For Vulkan ray-tracing across the various Linux test cases, the RTX 3080 Ti came out to being 47% faster than the RTX 2080 Ti. See those Vulkan ray-tracing benchmark results in full via this OpenBenchmarking.org result file.
