With having published some Darktable OpenCL benchmarks at the beginning of the week with 20 different GPUs (plus more follow-up benchmarks), it didn't take long before requests came in to see some fresh OpenCL Blender benchmarks.
For this article are benchmarks of 13 Kepler/Maxwell/Pascal NVIDIA GeForce graphics cards when testing Blender 2.78's OpenCL renderer. Unfortunately, no AMD OpenCL benchmarks for Blender yet -- the current open-source stack doesn't work until ROCm OpenCL support comes into play and the AMDGPU-PRO stack wasn't working for Blender OpenCL but was falling back to CPU rendering.
Tested NVIDIA cards with the 375.10 Linux driver include GTX 680, GTX 760, GTX 780 Ti, GTX 950, GTX 960, GTX 970, GTX 980, GTX 980 Ti, GTX 1050, GTX 1050 Ti, GTX 1060, GTX 1070, and GTX 1080.
All of these NVIDIA Blender Linux benchmarks were done from the same Ubuntu 16.04 setup. All of these Blender compute benchmarks were facilitated in a fully-automated and reproducible manner using the open-source Phoronix Test Suite benchmarking software.
