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, didnt found anything though.

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