(we're talking thousands of machines for one company) To retool with GPU heavy machines would be expensive (and hard right now given the chip shortage). Big shops have already invested in render farms with lots of CPU cores. It all really depends on you and what you do.īeing able to render on GPU (reliably and with files of any size) is a fairly new thing.

But comparing between an 8 or 12 core CPU and a 3000 series RTX, that's a tougher choice. So if given a choice between a thread ripper and a hot GPU, I'd take the thread ripper every time - more cores being used for more things. Most of the topflight engines come with both CPU and GPU capabilities so you have the choice.
So you are back to needing the CPU again. And not everything you do, that in theory can be done on the GPU, is actually done on the GPU and not every render engine can do all the tasks it should be able to on the GPU.
Rendering is not just about coloring the pixels. Sure the render when it finally gets to it might be zippy on the GPU but the set up for each frame might still take a long time even after you have shelled out for the big GPU. You may be rendering in Octane but that volume, or that simulation, or that mograph craziness or that cache you need to do before rendering is still being calculated on the CPU. So much of what you do is still done on the CPU, maybe without you realizing it. Remember, it's you being the artist that designs the shots, not the computer and GPU just doing what they do - adhering to physical laws can limit design/artistic freedom. Yes, cost is one of those reasons and existing architecture is another but both of those are supported by the fact that you can't always get there on the GPU if the client wants something specific or huge or you need to use a certain attribute in the software. There's a reason the big shops do look/dev on the GPU and render on the CPU. GPU's are easier to get a cool look quick, but I think they have also made people lazy and let the less experienced get to a look quicker on simple files (not a bad thing but everything ends up looking the same). Again it all depends on you and what you make.

GPU's are great for look/dev but depending on the scene, GPU engines can actually be slower to render to a full noiseless image than either of the built in render engines or other third party engines that can render either GPU or CPU. What render engine do you know? What one will you want to use? What kind of projects do you do? This is a harder question than you might think.
