This is my first question/post on Blender Stack Exchange, please forgive mistakes.

I recently run the Blender BMW GPU Benchmark in Blender 2.79.

My PC specs are:

  • 64gb of DDR4 Ram
  • i7-8700k
  • GTX-1080

The scene took more than 3 minutes to render, however other people around the internet report a render time of 1 minute or less for the exact same scene on the same graphics card.

I searched the whole internet for a reason or solution for the long render time, didn't find anything though.

Maybe someone here can help me. Any help is appreciated ;)

EDIT:

First, i used the 'wrong' benchmark file (1250 samples instead of 400 samples), thanks @itafan.

However even with the 400 samples file, my rendertime is lower than average. I now run the benchmark on several configurations: Windows 10 / Ubuntu 17.10, Blender 2.79 / newest exp built, enabled Intel Turbo Boost / Disabled Intel Turbo Boost, Monitor connected to gpu / igpu.

  • Win10 /Blender 2.79/enabled Turbo Boost /gpu : 1:35 min
  • Win10 /Blender 2.79/disabled Turbo Boost/gpu : 1:04 min
  • Win10 /Blender 2.79/enabled Turbo Boost /igpu : 1:28 min
  • Win10 /Blender 2.79/disabled Turbo Boost/igpu : 0:59 min
  • Win10 /Blender exp /enabled Turbo Boost /gpu : 1:32 min
  • Win10 /Blender exp /disabled Turbo Boost/gpu : 0:55 min
  • Win10 /Blender exp /enabled Turbo Boost /igpu : 1:16 min
  • Win10 /Blender exp /disabled Turbo Boost/igpu : 0:42 min
  • Ubuntu/Blender 2.79/enabled Turbo Boost /gpu : 1:35 min
  • Ubuntu/Blender 2.79/disabled Turbo Boost/gpu : 1:04 min
  • Ubuntu/Blender 2.79/enabled Turbo Boost /igpu : 1:28 min
  • Ubuntu/Blender 2.79/disabled Turbo Boost/igpu : 0:59 min
  • Ubuntu/Blender exp /enabled Turbo Boost /gpu : 1:32 min
  • Ubuntu/Blender exp /disabled Turbo Boost/gpu : 0:55 min
  • Ubuntu/Blender exp /enabled Turbo Boost /igpu : 1:16 min
  • Ubuntu/Blender exp /disabled Turbo Boost/igpu : 0:34 min

As we can see, enabled Intel Turbo Boost seems to be affecting performance drastically, however, i have no clue why. Connecting the Monitor to the igpu also improves performance, but this should be clear. Note that on every test setup, Blender and the required hardware drivers were the only things installed on the OS.

Blender 2.79 BMW Benchmark GPU very slow on GTX 1080
