Before we started this test we wondered if Octane will prove its almost perfect scalability with a system using more than 4 GPUs.
And it did!
As a reminder Octanebench with 4 GTX 970 gpus was 332,17.
Now we used the same system software configuration. A GPU server with 7 exactly the same GPUs working on the same boost frequency scored 585,10. That is 83,59 per card.
Otoy’s Octane render in benchmark test shows linear growth of rendering speed with multiple GPUs machines.
Next time we will test some real life scenes to check if using Octane on our farm with 7 GPUs per server is really 7 times faster than rendering on one.
