Well, it would be application dependent of course. For instance at that price we are talking about a machine that was purchased because it needed to have 1.5TB of RAM and channels able to take advantage of it. I would imagine it indeed could be more than twice as fast if everything being done is cached in RAM instead of having to reference a disk. We are talking about having 4 monitors simultaneously display 8K video editing, or heavy database workloads you usually wouldn't see on consumer PCs for machines like this.
