He is using blender and FlipFluid addon that does simulation on CPU:

Ryzen 9 3950X is good enough for that, not ideal and I personally would invest in TR, but taking into account fast peace of work that he does /s it doesn't matter at all what he uses for those.
Hmm, thanks, I have looked at the page, and indeed they say they do not use GPU.
Did not look at the details of the method they use, but I am not an expert in the matter, and too long from my studies, so if they say so, we have to trust them - though actually, they don't really say that they would not get any advantage from GPU, just that they are afraid the effort to manage the switch CPU-GPU and back would be more than the gain, most probably, the algorithm they use is not so easy to parallelise.
At the same time, using the CPU increases the compatibility/portability, but there is not doubt that a simulator using parallelisation and any decent GPU would beat the performance of any desktop CPU, even the Ryzen 9, the mathematical performances are just not comparable.
But it becomes a bit of a philosophical point - that is what Wildeer is using, so, that is it.
