An intriguing Unreal Engine comparison featuring a whole range of high-powered processors has been carried out by Puget Systems, with the very expensive AMD Ryzen Threadripper Pro 3995WX coming out on top. The test also featured the Zen 3 Ryzen 9 5950X, AMD's Ryzen Threadripper 3990X, and even a Comet Lake Intel Core i9-10900K.

8-channel memory is a niche requirement. At least it performs any better in this benchmark at all.
For many scientific workloads (like CFD), twice the memory bandwidth means twice the speed. TR Pro is hands-down the best CFD processor right now. I don't know why reviewers keep doing TR Pro comparos for workloads that don't benefit from the extra memory bandwidth.
