igorslab has results for Blender, which is said to measure pure computing GPU performance with OptiX, CUDA or OpenGL:

Code:
Blender RTX 2.9 BMW   

Card                  abs    1/rel

RTX 3090 OptiX        10.72  3.71
RTX 3080 OptiX        12.54  3.18
RTX 2080 Super OptiX  26.43  1.51
RTX 2080 TI CUDA      39.82  1
AMD RX 5700XT OpenCL  88.87  0.45

Blender RTX 2.9 Fishy Kat

RTX 3090 OptiX        18.41  1.81
RTX 3080 OptiX        20.77  1.61
RTX 2080 TI OptiX     33.45  1
RTX 2080 Super OptiX  39.95  0.84
RTX 2080 TI CUDA      74.12  0.45
AMD RX 5700XT OpenCL 126.23  0.26

Blender igoBot Rendering CUDA / OpenCL

RTX 3090               81.58  2.50
RTX 3080              103.66  1,97
RTX 2080 TI           203.71  1
RTX 2080 Super        218.20  0.93
AMD RX 5700XT         338.52  0.60


Besides the varying hardware, OptiX versus CUDA or OpenCL make a great difference. Why? What does this mean for go AI?
