OctaneBench

Hi all,

Remember the OctaneBench competition from 2013? Last year we got around to actually implement it, but then a lot of things changed in the render engine and we decided to wait until things have settled a bit, to make sure that the benchmark results are still relevant for later version 2 releases.

After some more polishing and tweaking we can finally release the OctaneBench based on version 2.17. It allows you to run a standardized test on one or more GPUs and store and upload the results to the OctaneBench result data base. OctaneBench can also be called via command line which allows you to automate testing. And you can take the OctaneBench resources and run OctaneBench on any OctaneRender Standalone version 2.21 or higher.

NOTE: When you run OctaneBench and upload the results to the database, it's important to not only benchmark the full system, but also sub-configurations and single GPUs. This way we get better statistics of the performance of each GPU model, which is relevant for most people who use the OctaneBench results to make a decision about which GPU to purchase. Thanks a lot in advance for participating and helping to create a representative overview of GPU hardware and its performance.

You can find the archive, more details and a link to the results page on the OctaneBench page. Here are some screenshots:

Happy benchmarking!

Pressing on this thread I though to myself..
"not again, another benchmark thread.."
- haven't noticed a fact that this was written by devs =)
but my face brighten up instantly seeing Julio Cayetano scene!!! =)

Thanks Guys!!! This is very nice addition to Octane tool-set! =)

P.S. great to see average & maximum scores! =)

I guess Your result will be "the max" on 780s =DDD..qurious 'bout it man!

First tests done :)

Marcus, if this is possible please add some more statistics to OctaneBench:

1. Core and memory clocks for each of gpus - these parameters affect strongly final scores.
2. GPU Voltage (under rendering only) - its level gives us a general look of how hard the gpu is used.
3. Cuda cores for each of gpu + total cuda cores. A 'final score per cuda core' would be really nice. If someone has 3k vs 20k it would be great to look at relative scores.
4. GPU temperatures recorded right at the end of tests - average or starting temps are irrelevant.
5. Option to select by a user if the system is water or air cooled.
6. For those who have power draw meters an option to enter real power consumption of entire system would be nice.

So the final score would look like this:


Octane version:
2.17
Operating system:
Windows 7 64-bit
Devices:
GeForce GTX TITAN @ 2688 cuda cores, 1293mhz core, 7000mhz memory, 1.2V, 37C, water cooled
GeForce GTX 780 @ 2304 cuda cores, 1293mhz core, 7000mhz memory, 1.213V, 39C, water cooled
GeForce GTX 780 @ 2304 cuda cores, 1293mhz core, 7000mhz memory, 1.213V, 40C, water cooled
GeForce GTX 780 @ 2304 cuda cores, 1293mhz core, 7000mhz memory, 1.213V, 41C, water cooled

Total score
421.244591

Total score per cuda core
421.244591/9600 = 0.4387
# of cuda cores 9600

Total power draw
955W

PS. From the test it seems that 980 is really great for PMC kernel - much better than 780 or titan. I'll run separate tests soon

I would like also to change GPU for comparison..not to see only 980 ;)

Thanks for your feedback. These are all valid points and we try to attack them in some future version. Unfortunately, there is currently no way to map a CUDA device to a device in the NVAPI.

OctaneBench is mainly meant to 1) allow people testing the render performance of their system and compare it to results in the database and 2) to give others at least some indication what to expect from a certain GPU. Our hope is that the current version does that good enough. It's certainly not perfect and with version 3 of Octane we will likely update OctaneBench again and then try to implement your and other suggestions.

I think this could be very helpful.

Using a GPU as reference was just a way to give the scores some meaning. Otherwise the numbers would have been very abstract.

In theory, we could recalibrate the score for some other device, but that would need to be done on the results page and I'm not sure how much work that is and how much stress this would put on the web server. I will ask Tim and Chris, what they think.
