it’s hard to tell but in breaking up a cube with tons of subdivisions with a Voronoi Fracture with a source with 5000 points I was getting pretty good speed until I turned on detailing. I’ve got a threadripper which is about the same speed as your CPU (single core) but I do have a 1080 so maybe that’s where the difference is, unless your object is, in some way, complex enough to be slowing the process.
