Here a quite common question that I have found on forums but without a satisfactory answer : with cpu is faster for flow simulations?

I have the impression my workstation is not optimal for flow simulation solving, and I have to face a big workload every day.


The actual system is (see file attached):




HP Z640 Workstation


NVIDIA Corporation


NVIDIA Quadro K4200

2x Processor      Intel(R) Xeon(R) CPU E5-2630 v3 @ 2.40GHz, 2401 Mhz, 8 Core(s), 16 Logical Processor(s)


According Solidworks benchmarking I have a 5,6 sec score on simulations.

According intel benchmarking 1239 marks. And is not improving with any setting of the tuning intel utility.


In the Solidworks benchmark list intel 7 seems from far better then any xeon, but some pc vendor propose still xeon as best solution for simulations with Solidworks (as APEXX).

here my benchmarking:

looking at 2018 benchmarking (simulations) i7 7700k seems the best (at simulation score 16,2?? I have 5,6! I suppose with the year 2018 there is different benchmarking and 2017 2018 perfoemance index cannot be compared?))



No intel i9 nor AMD appeared on the list.


Here what some vendors consider as fast workstation this:



but according these i9 is better:


what I have understood I need a balance between core frequency and core numbers.


According you, which is the fastest workstation or cpu for flow simulations?

i7,i9 or xeon, and which one with which clock frequency and core number?

Kind regards,
