we are talking about a computer for a user who wants to practice and take away some satisfaction.
anyway, even for an advanced user, why do you think xeon is better?
the only area where I consider superior xeon; it is in case you want to attack 3 or 4 think client, so as to make more people work with a single computer.
In all other cases, in cad, I believe that what counts is basically the brute power of the single core. and in this I do not believe that xeon or thredripper are better than i7 or ryzen.
What makes you prefer? What documents, tests, analysis, reviews have you seen?
Save gil, that statement was more generic/didactic (and I also realize it out of topic) to answer the question of alecs:
"- How come you propose amd and unintel processors? Are they better to work in cad or is it an economic matter? "
about your question "on the advanced user" (depending on how advanced) xeon and threadripper have for a professional:
- are obtained from the central part of the wafer therefore, there is very low probability of having defects;
- support memories etc.
- typically the houses that sell ws with xeon/threadripper guarantee for those products also a guarantee of excellence (replacement within 24/48h);
- I leave all the cad software case certification/driver speech;
in summary reliability.
Then, as told by you, another advantage is when you work with the same model from multiple thin clients.
here we are talking about workstations of a certain level that you find in certain working areas ("series" in this sense).
finished this part (which only interests someone), about multicore:
provided that there are xeon even at 4 core/8 threads, in general now the cores pull you back. if one has to do basic cad (assiemi + turbulent) just and advances also an i3 (depending on the series, however) but, when it makes (and solidworks does) the core/thread count.
then about the user: is a graduate of engineering and, using solidworks and catia, I have deduced that the field is automotive/aeronautic therefore to me it seems normal that you can also deal with fem/rendering analysis.
At this point between what offers the market and the application that exploits more cores (rendering) I think that the 6 cores are a great compromise between efficiency, frequency, duration of the cpu and, why not, resellability of the platform.
Frequency speech: true that in the cad counts but, in modest opinion, if at equal core/threads I have to spend about 100€ more for an intel platform (modo+cpu+ram) than the amd I prefer the second and invest on a more performing gpu that gives me a relationship €/higher performances and halves me the times more marked than the only frequency.
