iray benchmark

Hi all.
I want to compare some cuda gpu cards, so I prepared very simple scene.
I hope you are interested in this.
Rule is very simple.

1. Download the scene here or here and render it. Post the rendered image only.(10min render)

2. Change the render option to 'Iterations'. I set the passes to 100. Just render it.
Post the render time only.

3. Post your CPU + GPU specs.

Here is some examples;

1.10min render

2. 100passes rendertime : 6m 4s
3. spec - CPU : xeon x3210 2.13Ghz quadcore, GPU : radeon

1. 10min render

2. 100passes rendertime : 33sec
3. spec - CPU : i7 860 (3.4oc), GPU : GTX460

Thank you


sorry for confusing, I edited the sample post so you can easily understand

Workstation specs:
EVGA x58 FTW3 motherboard
Core i7 960 CPU
12gb DDR RAM
Video card #1: Tesla 2050
Video card #2: GTX 470
Win7 64

10 minute render:

NOTE: The 100 iterations render pass for this scene was reached in 19 seconds with this hardware.

For what it's worth, here's an additional benchmark scene:

Of course, the attached images are all 10min renders.

You don't need to upload 100passes image because there are all the same result.

My purpose is that;

1. the rendered image quality comparison for the same rendertime with different hardwares.

2. the render time comparison for the same passes(image quality)

The attached image is for 1, and rendertime is for 2.


Sorry for confusing, I modified the sample post.

Ah, well the way you have it listed is extremely confusing then (at least for me). It looks like the text below the your renders would be the render time for those images. But now I understand the post.

At any rate I've adjusted my original post accordingly.

Ten minute result on a Core i7 920 with no CUDA:

Rendering 100 passes on the same machine took 2:11.

10 minute render on a Core i5 650 cpu with a GTX 460 with 768 MB of RAM:

Rendering 100 passes on this machine took :49.

100 Iterations Render

1:04 min

Here is the 10 min rendering:

Interestingly, I get no performance benefit when enabling the CPU + the 580GTX. Infact, I just get 1 second less. 42s vs 43s with gpu alone......

DO NOT USE CPU+GPU. Go read my posts in this thread. In my tests there is a ~10% increase in using just GPU over GPU+CPU.

100 iterations 1:30 ms GPU only.
using iray Manager and CPU only still 1:30 ??

It does score with the CPU alone though. So for a reason or another, i think the CPU doesn't handle workloads when a capable gpu is running... or it manages data to and from the gpu instead.. workload is never more than 75% on a true quad-core either... but is 100% on a dual-core /w or w/o hyperthreading.

[font='Verdana', 'sans-serif']Hi Guys,[/font]

[font='Verdana', 'sans-serif']I have just upgraded my computer and I don't think my computer is using the second graphics card. I have just installed 3ds max design update 6 for my 2X GTX 660, and the GTX 660 latest update. It is receiving power, but isnít warm while rendering. Any help would be greatly appreciated! [/font]

Smile new card - update

Received more RAM and a Quadro K5000 to add to the Workstation.

Rendering times for the scene went from 47.29 seconds down to 29.78 seconds for 100 iterations.

Pretty sweet, a 50% increase in rendering power.

- Dual Xeon X5690-3.46Ghz, 24 threads.
- Quadro K5000
- 36GB RAM

You would find though that a gaming card would give you much better results in iRay.
