dual e5 2680v4 or intel 10850k for CFD

minhkuoa7 · December 21, 2020, 23:52

Dear CFD user,

I would like to build a PC for my work, such as ANSYS Fluent (2D and 3D) or OpenFoam, but I am wondering which is better: dual e5 2680v4 (with 28 core 56 threads, 2.40 GHz ~ 3.3 GHz) or intel core i9 10850k (with 10 core 20 threads, 3.6 GHz ~ 5.2 Ghz).

Could you please give me the advice?

Thank you very much and look forward to hear from you.
Best regards.

Dual Xeon E5-2680v4 by a huge margin. It's not even close.

Correct, 8 memory channels with the dual XEONs vs. only 2 with the i9. That will make a huge difference.
