Iray Scene For Time Benchmarks by SickleYield Iray Scene For Time Benchmarks by SickleYield
This uses items that came with the DAZ Studio 4.8 Public Beta and the Genesis 2 Female Starter Essentials.  Please make sure you have both installed before attempting to use it.  The "set" is just a primitive cube expanded to a large size and given an Iray shader.  There are many materials here that are refractive, emissive, reflective, or use subsurface scattering.  They're based on DAZ's included Iray shaders, though I have tweaked the colors more toward the blue end to avoid loudly clashing green and red things in the scene.

I've tweaked the materials on the outfit as well, and added translucency to let light show through, but it's still using only the textures that were included.

If using CPU only or older cards, delete sphere 8 and sphere 9 (the two blue ones to G2F's left and right).  They have strong SSS in their materials, and Iray is lagged by SSS where it is not lagged by reflection or refraction.

---

My time benchmarks for a 400x520 (small) image size at the included render settings:

CPU only 1st machine (Intel Core i7-5930K 3.5 GhZ, 6 cores):  16 minutes to reach 90%,  22 minutes total

CPU only 2nd machine (Intel Core i7-4700MQ 2.40 GzZ, 4 cores): 27 minutes 47 seconds to reach 90%, 1 hour 22 minutes total

CPU only 2nd machine (Intel Core i7-4700MQ 2.40 GhZ, 4 cores) on modified scene without spheres 8 and 9: 14 minutes to reach 95%

GPUs only 1st machine (Nvidia GTX 980 x2, GTX 740 x2, all 4gb cards): 3 minutes 30 seconds

(I haven't yet tracked down drivers for Machine 2's GPU that will work with Iray in Windows 7, so I was unable to test that single GPU with it as of yet.)

Stock scene as downloaded, unmodified. All times are to full completion.

GPU Only 1 x Geforce RTX 2070  = 2 minutes 21.14 seconds (Optix off)
GPU Only 1 x Geforce RTX 2070  = 1 minutes 49.11 seconds (Optix on)
GPU Only 1 x Geforce RTX 2070 + 1 x Geforce GTX 970 = 1 minutes 45.78 seconds (Optix off)
GPU Only 1 x Geforce RTX 2070 + 1 x Geforce GTX 970 = 1 minutes 19.47 seconds (Optix on)

All to full completion.  My 2070 is the MSI Armor, i.e. non-binned chip at stock.  When I benchmarked before with just the 970 I didn't get any benefit from Optix.  It made little to no difference.  With the 2070 it appears to.

Thanks SY for this benchmark scene. I downloaded it a while back but did not use it until now.

Machine:  Core i7 4790K 4.0 GHz not overclocked
               GPU NVIDIA GTX770 4GB
               32GB DDR3 951MHZ Ram

RESULTS:

GPU only with OptiX ON    6 minutes
GPU only with OptiX Off  10 minutes

CPU only  90% completed at 19 Minutes 30 Seconds
             100% completed at 24 minutes

CPU + GPU* with OptiX ON  5 minutes 40 seconds

*NOTE: CPU + GPU produces a lots of heat on both the CPU and GPU and increase fans speed and noise.
Using only CPU or GPU to render heats only the one in use. overall temperatures keep low.
I got a max temperature on the 80s centigrade.


I found the results very helpful. Thinking about upgrading my card.

Thanks

Still confused with OptiX Acceleration, since on some scenes it really speeds up the render, while on some others it really slows down the render.

Thanks! I've been debating about upgrading my graphics card, so this was a useful test! I've expanded the test a bit as well, as I've picked up tips for speeding up renders from other places, so decided this was a good place to test them. I'll put all my results up.

acer Aspire TC-150
15GB Ram
Windows 10
AMD Radeon HD7000

Render results (rendering to 80%)

Standard render (no modifications to scene) 15 mins

Modifications tests:
Bounding box changed to planes, one side left open - cancelled render at 69%, over 15mins

Bounding box changed to planes, one side left open, hdri map and extra light, fstop and shutter speed raised (apparently more light in a scene, and a place for light to escape leads to faster renders...we'll see....) holy moly, they weren't kidding! I was sceptical, but the results speak for themselves - 3 mins 25 seconds!

bounding box removed, back and floor left as background only, lights and camera as last test - not much change from previous test - 3 mins 31 

bounding box removed, back and floor left, lights and camera as in standard render - render stopped at 70% - over 15 mins 


Best result - increasing the amount of light and fstop to compensate. I don't think having the planes surrounding the woman and spheres actually made it much quicker, I think that was more to do with the heavy sss on spheres 8 and 9. I rarely render over 80% (I always render larger and then shrink) so this was a very useful test for me. Knowing that i can shave my render time from 15+ mins to just over 3 without having to splash out on a new graphics card simply by increasing the amount of light and adjusting the camera to compensate, just rendering on CPU, and rendering with memory optimised instead of speed - I don't think I'll splash out just yet.  Out of curiosity, I rendered the second to last test again with the spheres 8 + 9 removed: 1 MINUTE 50!!!

Yes.  When I did this test scene originally I did not know that transmissive objects slow Iray down more than anything else!  You'll find that the Daz Originals skins that come with SSS set to 2.0 also render very slowly compared to PA skins with it set at for e.g. 0.7 or so.

First of all thank you. You are on the top of my favorites list for written and video tutorials. I have learned much. I mostly do 3Dlight renders with my laptop but have tried Iray. The renders timed out at 2 hrs, 4 hrs, and 6 hrs at 60 - 70% complete. At 12 hours it timed out at 98%. But that render was good enough to earn 3rd place in the freebie challenge. So with that in mind I decided to try your test render.

Well, new system built both 980 sc cards running @ 16x on PCIE 3.0 render time for this benchmark 2 mins 4 sec @ 5000 iterations with Optix enabled. Pretty pleased with that. So it looks like running cards @ 16x gives much greater raw throughput

I just finished building my new system; Intel Core i7-5960X @ 3.00GHz, 8 cores. 32GB DDR4 memory; and Titan X GPU with 12GB RAM.

I haven't OC the system yet, but built it liquid cooled for the specific purpose of doing just that and tuning for rendering. As I am able to afford it, more Titan X cards will be put in the system. :)

GPU Only: 3 minutes 44 seconds

CPU + GPU: 3 minutes 14 seconds

CPU Only 14 min 50 seconds.

Wasn't able to figure out OC yet, but will do what I can. From reading the comments below I tried the OptX Prime Acceleration and the CPU+GPU render time dropped to less than a minute to 90%; 2 min 16 seconds to complete!

My MacBook Pro took over 20 minutes to complete.

From what I've been reading, adding more GPU (without SLI) will improve time in a pretty straightforward fashion - so I wonder what I could expect from two or more cards -

Great benachmark - for me GPU render only works best (2 x MSI GTX760, 2 GB, non-SLI mode) - render to 100% (=5000 iterations only) will take 4m20s with Optix enabled and 6m.30s without. 

Activating the CPU in my case slows down the system. 
Note: Update your Nvidia drivers (CUDA 3.0 might speed up things)

An interseting note here : I was running two 980gtx sc cards with a 3770k and 32gig of ram. As my cpu only supports 16 pcie lanes the two cards ran @ 8x/8x. What I found was the when i removed one card so the remaining card was running at full 16x rendering times were smashed. This scene for example I can complete in between 3 and 4 minutes. Am upgrading to a 5930k soon which will allow both gpus to run @ x16 as there are 40 pci lanes on this cpu. Your cards pcie lane speed  seems to be crucial to using high end cards to their full potential. So in summary having 2 or more cards will become less productive if they are bottlenecked by their throughput. Hope this helps.

Hi - clearly your PCI lanes are slowing down the render as I achieve the same 4 minutes with 2 x GTX 760 but running in full 16lanes each. Also note to deactivate SLI in your driver settings in case you have this for gaming.

GPU+OptiX Prime Acceleration: 3mins 41secs

It would seem that the CPU barely makes a dent in the times, despite being a 6 core i7, and the Optix Prime Acceleration makes quite a difference. 

Im running this benchmark in Windows 7.
I wanted to run it in OSX 10.10. but I keep getting the error:

DAZ support confirmed that the issue is with the Nvidia CUDA drivers for mac, and it is an issue that Nvidia are aware of and are working on a solution.
Hopefully it won't take too long, as so many scenes I've created have had to use only the CPU, which just doesn't cut it :(!
