Rendering with the CPU instead of the GPU

wintoons

Hi Guys, 

This is just a curious question, does anyone use only the CPU for rendering instead of their GPU?

I was wondering, with the new CPUs which have now got more cores and threads, do they perform just as good as a GPU or no way near as a good?

Thanks

If you're talking about iRay then yes, there are people who render on CPU only but they all seem to be on older hardware.

I think someone did do a 2990WX test but IIRC it was still slower than just about any GPU.

Yeah, I kinda guessed it wouldn't make any difference. An Nvidia GPU is still the best choice.

I have an 8 core 16 thread Ryzen and it renders a benchmark scene in 20 minutes. My 1080ti does it in 2 minutes.
