Hi guys

I’m working on a GPU vs CPU rendering comparison which will be the subject of a podcast I’m working on with my colleagues. Every day I work as a support guy on a cloud render farm and I have my experiences with both CPU and GPU rendering (and I’ve seen experiences of our customers) but I’m very curious about your opinion.
 
If you use GPU render engines what are the reasons? The most common reason I’ve heard about is speed, but of course when you have access to more than one card or processor then I guess it’s rather speed\money.

What is interesting for me is are there any other reasons for using GPU render engines? Do they give a different, maybe cooler look, any features which CPU engines lack or type of subjects where they give better effects?

I’m very curious about your opinions and impressions when it comes to GPU rendering. What are the pros and cons?

By the way – when it comes to GPU unbiased engines – the GI and glossy reflections\materials highlights are computed as the same thing, right? For example, in CPU V-Ray GI and material reflections are visible on two separate layers\passes.

When planting a large number of plants, the GPU preview speed and adjustment practicality are much better than the CPU, and the GPU renderer is not as sensitive as the CPU rendering (the higher the resolution, the longer the drawing time) and the GPU can provide. Better noise reducer
