NVIDIA GeForce GTX 1080 Performance Review: Pascal, The New King

Steam VR Performance Test, LuxMark v3.1

The Steam VR Performance Test measures a system's performance using a 2-minute sequence from Valve’s Aperture Robot Repair VR demo. After running the test, it determines whether your system is capable of properly running VR content at 90Hz and whether or not the visual fidelity can be increased to the recommended level for a given application. Both a system’s CPU and GPU are factored into the score.

The GeForce GTX 1080 put up the same score as the factory-overclocked GeForce GTX 980 Ti in the Steam VR Performance test. Note, however, that this benchmark doesn't benefit from the GTX 1080's simultaneous multi-projection technology, and also factors CPU performance into the mix. The bottom line is that the GeForce GTX 1080 is arguably the best, single-GPU powered graphics card for VR applications, though it isn't fully exploited in this test.

LuxMark v3.1
OpenCL Benchmark
LuxMark is a cross-platform, Open CL-accelerated 3D rendering benchmark. It's based on the open-source LuxRender physically-based spectral rendering engine, which accurately models the behavior of light and supports high dynamic range. LuxRender also features a number of material types to allow rendering of photo-realistic and artistic scenes. LuxRender is free software, licensed under the GPL, that offers plugins for packages like Blender, Maya, Cinema 4D and 3DS Max. We ran all three of the scenes included with the benchmark using the GPU rendering mode.

The GeForce GTX 1080 didn't perform quite as well as expected here. With its high clocks and 9TFlops of peak compute performance, it should have performed better here. We mentioned the results to NVIDIA and a bug report was submitted, but we don't have any additional information to share just yet. The GTX 1080 outran the Titan X in the most-taxing Hotel Lobby scene, but trailed otherwise.
