Cycles Render Time for Lecture 99

CPU: Intel I7 6700K 4.0 GHz
GPU: Nvidia GTX 1080
OS: Windows 10 64 bit

A note for 1080 or 1070 users who have a CUDA kernal error (or some such), I needed to download the release candidate for blender 2.78 in order to get rid of the error. It’s working so far, but it isn’t a release build, so keep that in mind. It is available on the blender website.

Best Times are on the bottom of each compute type. I was really expecting amazing results compared to the 770 in the notepad, strange:

Times:      CPU/GPU:      Tile Size:

  1:22.31         GPU             512x512
  1:33.59         GPU             1024x1024
  1:31.65         GPU             1920x1080
  1:25.92         GPU             256x256
  1:31.84         GPU             960x540
  1:17.04         GPU             480x270

  4:01.11         CPU             240x135
  4:17.24         CPU             256x256
  3:37.29         CPU             128x128

GPU in HW Monitor was running at 100% with a clock of 1924MHz. I walked away for the CPU renders, so I didn’t check it.

edit: After resuming the lecture, I figured I should try lower tile size for the CPU, results:

Times:     CPU/GPU:    Tile Size:

3:25.18     CPU         64x64
3:22.43     CPU         32x32
3:21.25     CPU         16x16
