Best workbench specs for PLAXIS3d

This should hopefully be a pretty self explanatory post. What would be the best desktop setup to run PLAXIS 3D as fast as possible without being wasteful?

Currently I'm thinking:

AMD Ryzen 9 7900X 12 Cores (my understanding is PLAXIS 3D can't really make use of more than 8 cores, is this correct?)

Corasir RAM 2 x 16 gb 6000mhz CL30 (is there any benefit to faster RAM?)

For storage I was going to go with a 1tb or 2 tb NVMe SSD. Is there any benefit to going with PCIe Gen 5 over a cheaper Gen 4?

  • Thank you for your response though frankly I had read most of that as that's the basic information provided by Bentley. I was hoping for a more in depth understanding including benchmarking results.

    I am also not sure about the recommendation for a Threadripper. Our benchmarking showed limited increase in performance with more cores. I actually had a Ryzen 7600X out perform a 12900KF. Mind you that was only after we disabled the e-cores as for some reason PLAXIS 3D cannot handle latest gen intel it seems. 

    Has Bentley performed any proper in depth benchmarking analysis? Is that published anywhere? Given the significance of CPU performance has RAM scaling been assessed? How would 5600 mhz CL40 RAM impact the result instead of say 6000 Mhz CL30? Are the calculations in anyway benefited from additional L3 Cache on Ryzen X3D parts?
