xeon vs ryzen threadripper

[Salvatorelg]

hi I am a mechanical engineer and I am thinking of buying a workstation to make structural fem calculations (abaqus, ansys, nastran etc) with quite heavy models of 3/4 million knots. my question is: is it better to buy a workstation with two sockets with intel xeon scalable silver 4216 (2400 euros) or 4214 (1500 euros) or a single socket with amd ryzen threadripper 3960x (1600 euros)?

the fact is that xeon processors are very well known in the server field and among other things in this field the amd proposal are epyc processors and not ryzens. However, with a price of 1600 euros the ryzen 3960x has almost triple scores in the benchark passmark. Does this huge advantage also apply in our fem simulations?

thought of using a different tool for fem analysis?
Do you know highir simsolid?

 

[Salvatorelg]

I don't know him, thank you anyway for the suggestion. the question however concerned the hardware to use for fem analysis.

hi savior, if memory does not deceive me the number of knots is related to the degrees of freedom then so to the good mortgage that you get at least 12gb of ram only for the fem.... We make 16gb minimum. If I'm wrong, correct me.
the new ryzen threadripper 3960x has 24 cores and 48 threads so it seems a great presentation ticket for a cpu from fem and if coupled to a good motherboard can be base for a great workstation with full support to ram etc if necessary. I'm going to see you https://www.google.com/amp/s/www.tomshw. it/hardware/ryzen-threadripper-3960x-recensione/?ampaccording to me in the performance/price ratio the ryzen comes out winning.
until today with what cpu you worked and how much ram you used?

Unfortunately the calculations I make occupy on average 200 gb of ram, are related to the degrees but I do not remember with what formula. However so far I have worked at a multinational with 140 core servers and xeon 6132 processors. I was also aiming at epyc

What? ! !I in the estimate based on an old rule 1gb of ram every million degrees of freedom considering a knot with 3 gdl (estimated good).
if you exploit all this ram you need serious artillery by pointing on high-end ws because motherboards for ryzen 3960x stop at 256gb for example this https://www.msi.com/motherboard/creator-trx40/specificationwhat budget do you have?

pure computing power, choose amd. However you have listed a number of software that I imagine are different from each other. I use nastran, and I read in his guide, which is optimized for intel processor.
Moreover, with my models do not scale in an exaggerated way, so I hardly use more than two/four cores. so I use intel. Incidentally my models are typically shell, up to a couple of million items.
if instead the program you use scale beyond the 12 cores then and it was not written specifically for intel, then better ryzen.
then there is the memory speech, with xeon, you can address a lot more memory than you can do with ryzen, which stops at 256gb as it points out taurus. so, if this is a limit, then it is necessary to use xeon.
I, who can't make the processors scale more than once, I prefer the I9 intels with maximum processor speed. typically use from 20 to 70 gb ram.

about 4000 euro

about 4000 euro

I took a look on the net and at first sight the figure seems to me bass especially if we talk about ws of the ibm-hp-lenovo, the only way is the assembled but you will struggle to stay inside with the figure.
I'll give you an example

• processore ryzen threadripper iii 3960x 3.8ghz 24 core 48threads fino a 4.5ghz in turbo boost
• 128gb ddr4 3000mhz
• ssd m.2 1 tera byte samsung 970 evo plus
• hard disk sata3 2000gb seagate
• masterizzatore dvd
• mainboard amd trx40
• video nvidia picture rtx 5000 16gb
• scheda sound 7.1 onboard
• 2x lan 10/100/1000 onboard
• modulo wifi 300n
• 1000w Modular Power Supply Certificate 80+ Gold
• case tower atx fonoassorbente
• windows 10 professional

price 5949€
We suggest you delete the rtx 5000 and enter the rtx 4000 save about 1400€ that you can invest on the ram to get to 256gb.... then there would be to say that in my opinion a 1tb ssd for me is small speculating that the output files of the analysis are large enough and that swapping on the mechanical hd slows everything, so at least a couple of ssds from 2tb each are obligatory (until you think of that).
another way is to take a ws used with a good cpu and fill it properly with ram, ssd, vga.

I have three ssd m2:
one for operating system 512mb
one for pre/post data I think 1tb is enough, the completed analyses move to another disk, certain depends on the quantity of output, for example a nonlinear with results for each step makes many more data output
the third disk for scratch files, where the solutor leans for what is not in memory, even here, the size depends on the solver, 512 should be enough.This disk must have faster access.
the video card, to make fem, can be more ecomonica, the fem models normally take less cad resources.
I repeat, you have to choose a solutor, it is not realistic that you use three different ones of that level (abacus, nastran, ansys), otherwise the cost of the machine would be the least of the problems. each of those systems costs several tens of thousands of euros.study on the selected solutor manual as building the machine. if it parallels very well, go on a ryzen. If you prefer the speed of the processor, I would go on an intel. With that budget, I'd forget the xeons.

hi savior, if I can be useful this is an example of what I mean by used ws https://www.ebay.it/itm/hp-z820-wor...ispr=1&hash=item23ca7b1455:g:ko4aaoswvuxdocoycan stay up to 512gb of ram and processors are nothing bad indeed.... on the net they find of various prices and characteristics and could be a good base from which to leave.
