Title: Nvidia Cuda Cores
Post by: bertv on 2021-05-11, 09:47:27

Hi,

My system has a Nvidia Quadro RTX 4000 card https://www.nvidia.com/en-us/design-visualization/quadro/rtx-4000/ (https://www.nvidia.com/en-us/design-visualization/quadro/rtx-4000/)
Containing 2304 Cuda cores. In my understanding those cores can be adressed as CPU cores.

When I monitor the GPU in my task manager when rendering a Corona Render engine scene in my 3Ds max, I see no activity for the cuda cores.
I red that Corona Render engine is CPU based. But why isn't it usign the GPU cuda cores acting as CPU cores?

Regards,
Bert

Hi there!

Except for denoising purposes (Nvidia AI denoiser only) your GPU won't be utilized during rendering with Corona. 3ds Max / C4D will use it to display the viewport but it will by no means help you render faster - Corona is a CPU rendering engine and you can't "repurpose" GPU cores to be used as CPU ones because they work in a completely different way.

Ok, thanks for the information.
