Soba Noodles Benchmark scene (CPU and GPU)

Heh. You showed exactly what I was talking about Hope you know, how proper DOF looks like

P.S. Scenes attached. Guess, where proper DOF is.

This is because you are using a standard max camera with the ancient dof override in the render settings. If you create a physical camera, both images look identical in CPU and GPU.

i will also release Blender version (i hope so)

Would be nice, will try it when ready.

Hey guys,

Blender version is ready, since it's not for this forum i wont be sharing it here, but you can find it on the same Behance post where Vray version is.

Render time for blender is 14m 06s for view 1 and 12m 10s for view 2 their GPU compute cycles used in both cases.

Thank you.

Well, I showed scenes and I thought, it is clear, that standard override renders wrong with GPU. I'm not using any DCC specific tools here, 'coz I have to match stuff between render engines It is great you guys don't have such an issues.

P.S. It is not an "ancient dof override".

Thanks for the scene, it's pretty cool, I'm pretty annoyed of how long it takes on the overblown areas but ofc I'm not a render guru, maybe that's how it's supposed to be.

Max 2020.3

2x 2080 Ti RTX NVLink

I thought the CPU would be faster


EDIT Max 5 Beta 1 Render info :

Max 5 Beta 1:

CPU 22:34

Thanks for trying it out, amazingly fast on 2080ti.

So after some testing I find why the render time for my earlier test was way to long .. it is because the default settings when I opened the file is set to use CPU only for the GPU rendering : ))
So I did the tests again and the render time is much better now :

VRay GPU 5.0 : 14 m 40 sec
VRay GPU 4.0 : 11 m 7 sec

render time for CPU for the record was : 36 m 37 s on Vray 5.0
I probably should do the test on Vray 4.0 again .

btw do you guys disable CPU when rendering with GPU ? or rendering with both ?
in my case I'm using both for rendering .
my machine specs again : Dual xeon CPU 2650v3 , GPU 1080 ti , 64 GB Ram

Mine won't render when I leave the CPU option enabled if I'm doing GPU

You could render a test without CPU. I did a test some months before and the hyprid mode caused a slow down. Cuda rendering on CPU is ineffective and the CPU power is missing to feed the GPU. My experience is if you own powerfull GPU (for example 2x2080ti) than hyprid doesn't help.
