1080Ti Benchmark results for Octane Render

We have found the 1080 Ti to outperform all other GeForce GPUs available in Octane – By a pretty substantial margin!

 

SOFTWARE:

For these tests, we used the Octane Standalone Demo (Version – 3.04) – https://home.otoy.com/render/octane-render/demo/

We downloaded the “Simple Test Scenes” Demo suite folder, and used the demo scene named OctaneBenchmark.

Using the scene panel on the left, we right clicked on each render target, and ran each render to completion.

These render targets are:

  1. RenderTarget DL (Direct Lighting)
  2. RenderTarget PMC
  3. RenderTarget PT (Path Tracing)

HARDWARE

We used the following spec’d Sonox XL Workstation to run our tests:

CPU: Intel i7-6800K

Motherboard: Asus X99-E WS

RAM: 32GB Corsair Vengeance 3000 MHz

Drive: 250GB Samsung 850 Evo M.2 drive

PSU: 850w Corsair RM850x

OS: Windows 10 Pro

We tested the following GPUs:

  1. 6GB GTX 1060
  2. 8GB GTX 1070
  3. 8GB GTX 1080
  4. 11GB GTX 1080 Ti

RESULTS

As you can see for both Path Tracing and Direct Lighting renders, adding a second 1080 Ti almost exactly halves the time to render the scene. We have found this to be true when adding even more cards to the system.

With the PMC render, we found that the 1070 actually out performed the GTX 1080, rendering the scene around 7 seconds faster – We actually grabbed a couple of extra cards to confirm there wasn’t an issue with one of the GPUs, but it gave us the exact same results.

We aren’t too sure how the PMC kernel utilises the system, but we would guess that this is related to the on-board memory on the GPUs. If you have any idea why this occurs, please let us know in the comments section below!

You can download the screenshots from our tests using this Google Drive link.

We recommend our Sonox XL X1 system for Octane, as it can hold up to 4 high powered GPUs making it ideal for any and all rendering tasks. For smaller tasks, our Sonox Mini X99 is a great workhorse capable of housing up to two GPUs if space is at a premium!
