Animo uses VRAY so his renders are 99% GPU dependent. The CPU doesnt do much at all.
My rig has a 1080TI and a 2080TI but I am going to buy a new machine with 3x 2080TIs to cut my renders from 5 minutes per frame down to 2 minutes.
Also, a LOT of studios use GPU render engines like VRAY or Redshift (I use Redshift) because they are 10x faster than CPU render engines. I used to use Mental Ray/Arnold for CPU rendering but GPU render engines are just so much better in my opinion. Same quality but unbelievably faster. I will never go back to CPU rendering for anything in the world!
Anywho, Animos stuff is wonderful and I'm sure his next piece will be worth the wait
