Nvidia or [?] and Intel Denoiser use in an older Nvidia card


I am using a Nvidia p4000 [8GB] in a laptop with two attached monitors [both FlexScan S2133 in Portrait Mode; 1200 x 1600 resolution] . All of the rendering work is done in Rhino 7 Raytrace Mode with the UI spanning both monitors. Using the mm scale template a final render might be 600x600 72 DPI and Final quality. Often when I am modeling I will set one or more view ports to Raytrace Mode so as to get a better feel as to how the design is looking [and move it around] e.g. it is looking horrible > scrap it.

Given that the GPU is technologically older and not very powerful am I better off using the Nvidia Denoiser or Intel Denoiser or perhaps simply select both in Tools>Options>Post Effects and let the system / Rhino choose [given this is possible ?] the optimal one.

Thank you,


My guess would be that the intel denoiser is going to be nicer on your hardware as in less load on the GPU.

But you can always try both in turn for say a day and see which gives you the best experience and results.

Hello Nathan

ok. Given that you have a newer / more powerful Nvidia GPU, does the Nvidia Denoiser seem to work better? Or are their to many other variables to make an “in most cases” statement.

Thank you,


Hi @litwinaa ,

Personally I use the Intel Denoiser even though I could use the Nvidia one. The results are identical in most cases in my experience and this leaves the Nvidia card free to just do the raytracing. The Intel denoiser will work on the CPU and despite the name is not only for Intel chips.

I do it for the same reason - not using GPU for denoising.

Also I think often the Intel denoiser gives a bit nicer result (in other words I don’t feel the results are 100% identical. Close, but not identical).

Me too, but I have to do some more comparisons one day.

And I wish denoising was a default, will it be in v8?

The denoisers are separate plug-ins not bundled with Rhino. I don’t think they will be bundled with Rhino 8 at least.

I understand that they are separate right now, but IMO the technology is so important that the intel CPU version (that works on all systems) should be integrated and ON by default. It saves both time and a lot of power too, and will show off the power of the integrated renderer (cycles) even better.

Now users have to first learn about it, then install it, reboot and then turn it on for every single file (or the default template if they are so advanced that they actually do so…)

So please consider.

At least consider moving it from document setting and over to system setting.

IMO the nVidia one can be installed on demand, and then chosen on a higher level.

I said the same thing as you during development. If memory serves, they had to be separate user installs due to the licensing requirements of these denoiser plugins. I’m not sure if that has changed but @andy may.

There was also a concern about the overall size of the Rhino installer with added packages that can’t necessarily be used on all hardware.

That’s a good point, and that’s why I suggested the Intel Denoiser, as far as I know this works on all (PC related) machines. Correct me if I’m wrong.

But IMO in 2022 denoising a render has become the standard.

I agree on the bloating of installers though. Maybe it could be an option page for stuff like this when installing? Many installers has that.

I am draw back to this tread having [in more cases that I would like to admit] needlessly increased the render time by forgetting to enable the Denoiser and for inexplicable reasons did not proceed with the work flow that Holo suggests with regard to the default temples. Maybe to help the sometimes absentminded me(s), and to inform others, a help tool message could trigger that would briefly describe the Denoiser App and perhaps link to the Rhino help file with the specifics e.g. Nvidia and Intel versions etc. And I am finally going to proceed as Holo suggests.

Thank you,

p.s. The message could also have a “so not show again” checkbox
