I suggest running those again. Your GPU and CPU shouldn’t be getting the same times across the board. I had that happen and discovered that the program was using my CPU when it should have been using the GPU. Go to “User Preferences” and make sure you have CUDA selected for the GPU Render, your GTX 1080 should be blowing my 1070’s 60.85 seconds @ 480x270 out of the water.
