My bad, I didn't saw that. Thank you
These are my results:
CPU: i5 4690k
RAM: 16gb
GPU 1: Asus GTX 1070 DUAL 8G OC
GPU 2: Gygabyte GTX 1070 mini ITX OC 8G
Software: Asus GPU Tweak II - OC Mode
2xGPU + CPU: 2m 47s
2xGPU + CPU OptIX Prime: 1m 36s
2xGPU: 2m 37s
2xGPU OptIX Prime: 1m 42s
Asus (display attached)
1xGPU: 4m 50s
1xGPU OptIX Prime: 3m 03s
Gygabyte (no display)
1xGPU: 4m 52s
1xGPU OptIX Prime: 2m 58s
Funny thing that I used to believe that CPU always slow the process, but with OptIX seems to reverse the logic.
I don't know how people use two GPU so close together without worrying about overheat. I bought the mini ITX model to give space to the dual fan GPU already installed, even so Asus reached 76º, before the other card it never passed 72º. The cabinet has 2 front coolers, 1 back coolers and 2 top coolers creating the air tunneling.
GPU time: 2:02
CPU + GPU 1:41
<edit> CPU only 8:57
Dual Xeons + GTX 1080ti
Interesting. That's almost exactly the % improvement I got when I turned on the CPU's in my Ryzen 7 1700. Yours comes out to saving 20 seconds on a 120 second render by turning on your CPU and all its 15 (?) cores, which is 17% improvement.
My render went from 11 minutes 30 seconds to 9 minutes 30 seconds by adding the 8 cores, 16 CPU's in parallel with a GTX 1070, which is 17% improvement.
Interesting.
EDIT: By the way, it wasn't rendering this reference scene it was another one I'm working on. But the % improvement might be arguably independent of the specific scene.
If it's a different scene, it really doesn't mean anything. It has to be the same scene. Every render is different. I just did a render that was more than a 30% difference. It was an animation. It depends on what's being rendered. Really, these type of benchmarks are interesting for entertainment value, don't take them too seriously.
Okay, I just did the reference scene. GPU's only, 3 minutes 15 seconds (like I posted here before). With CPU's added, 2 minutes 41 seconds. That's 34 seconds faster in a 195 second GPU-only render. The percent improvement is 17.4%.
That's entertaining
Try a more complicated scene. this scene is too short. The tolerances are too small. If you get the same result, maybe you're on to something.
I told you in the post you responded to, an 11:30 render. It shaved 2 minutes off.
Oh, I forget you are rendering stills. Perhaps that's the difference.
Hi guys! New on this forum but using DAZ for sometimes now.... Ive just finished building my new computer so I post my results here:
Here is my Config:
CPU: i9 - 7900X (3.3GHz)
RAM: 32Gb DDR4
GPU: 1080 Ti Founder Edition
Here is the results:
GPU+CPU+OptiX: 1 minutes 56.51 seconds
GPU+CPU:2minutes 45
GPU+Optix: 1 minutes 55 seconds
GPU:3minutes 16 seconds
Maybe someone will find it interessant to see some bench with new i9.
Hmmm must be something off somewhere I'm running a Ryzen 1700x and on a single 1070ti its only 18 sec slower
I would expect a bigger difference
I've watch your bench :
"From my proudly self built 2 day old rig:
I7-7700K
Asus Strix Z270E
Asus Strix 1080 ti (overclocked out of box)
16 g RAM
--------------------------------------------------------
2 min 0.56 secs
GPU + Optix Memory
1 min 53.98 secs
GPU + Optix Speed
3 min 19.88 secs
GPU - Optix Memory
2 min 16.49 secs
GPU - Optix Speed
With these different settings, is the final render quality the same? To my eyes it is."
I dont really understand what do you mean by optix Memory or Speed, I just have OptiX acceleration. However GPU+Optix is at better 1min53' and mine 1min55', considering my GPU is not overlclocked and your's are, I dont really find it strange, is it? But I've the last driver.
For the CPU time its more strange.
About GPU time, it's +/- the same of all 1080ti benchmark on this forum.
There's a render setting where you can set the optimization to memory or speed. I always keep it at memory because I m happy with the speed. Those figures are with an older Nvidia driver. From memory, things are 10 seconds or more faster. Do your benchmark with optix on , optimization speed. It should be pretty good. I thought your cpu would speed up the scene set up before the gpu render. You have a really nice cpu. I'm afraid to ask how much your build cost.Ok I will try it!
Hmm i9 seems pretty good for a lot of task, specially encoding etc, but less good at gaming (im a gamer too and Im streaming too...). I would like a CPU good a twice, so I choose i9 even benchmark seems to show that with overclocking, the temp are very (very) high -even with a good watercooling- which is a little scary :/ . Ive just finished building the computer yesterday...So I need to practice a little more I guess :)
For the price..... Yes its...... high.....very..... But I've always wanted to build me a "monster" with custom watercooling etc etc.... So well I make a gift for myself;)
Sinkty00, that sounds like an awesome build. What kind of times are you getting with stricly just the CPU?

Okay, as a public service I have compiled many/most of the results in the previous 5-10 pages into a spreadsheet, so you can look at the list and get a feel for what type of relative performance you might get from each type of GPU.
Keep in mind that I tried to extract only those GPU only results, with Optix enabled. And also keep in mind that the render times I list are ballpark numbers only, and are usually an average of the posted results, which can vary depending on how the systems are configured and how the tests are performed. So figure they're +/- 10 or 15 seconds.
And I've sorted the results in order of decreasing render times.
Thx, I'll try a CPU only tonight, I will post the result!
Well here it is, for the one who are interest:
CPU Only with CPU: i9 - 7900X (3.3GHz) = no Overclock
Total Rendering Time: 14 minutes 10.36 seconds
Since you are sharing your i9 render numbers, I figured that I'd see how well it fared against dual 6 core Xeons (generation 1.5 i7 platform)
CPU only - 2x Xeon X5680 @ 3.33Ghz (24GB 6 channel REG ECC DDR3)
Total render time - 21 minutes 49.59 seconds

Here are the results with SLI:
GPU1 + GPU2 = 1m31.64s(initial) ; 1m20.95s (preload)
GPU1 + GPU2 + CPU = 1m24.17s(preload) ; 1m25.39s (preload)
Here are the results with SLI rendering mode set to 'Single GPU' under Manage 3D settings:
GPU1 + GPU2 = 1m31.67s(initial) ; n/a (preload)
GPU1 + GPU2 + CPU = 1m22.97s(preload)
Here are the results with SLI diabled:
GPU1 + GPU2 = 1m31.97s(initial) ; 1m19.84s (preload)
GPU1 + GPU2 + CPU = 1m22.64s(preload) ; 1m23.5s (preload)
So my conclusion for this particular rendering is that SLI or not, it doesn't make much of a difference and adding CPU to the mix doesn't help rendering times
Does anyone have an idea why my characters skin looks way more grainy than the one posted on the first page? I have a gtx 750 ti. Took about 10 minutes to render.
Your image seems to be a bit larger!
That is because Iray does not use SLI. What you have confirmed is that it does not matter if the SLI bridge is installed or not.
That means if you game in SLI mode, you do not need to dissable or uninstall anything to get the most out of Iray.
K so here's my results with system specs- The ones that matter most anyway.
i7-5820k 3.3Ghz 6-Core
64GB DDR4 RAM 2133hz
GeForce GTX 1080 Ti SC Black Edition 11GB

I included the full print screen so you can see the GPU Temperature as well as the time and size of the image.
One was saved as a Jpg. The other as PNG. When you save as Jpg you lose quality for the benifit of a smaller file size. Saving as a JPG, it is stripped three dimensional information pertaining to it. And is only presented in the RGB format. (Red Green Blue)
For a more professional finish always save a PNG. Which is uncompressed with no data loss.
I gave up at 31 minutes lol. My laptop is a pos though and that is straight cpu

Thanks JamesJAB. Looks like your results confirm what others have seen when comparing a 1080ti to a 1070, where the 1080ti gives maybe a 30-40% render time improvement over a 1070 (2 minutes vs. 3 minutes).
