Worstation choice

Dear support,

I'm thinking of upgrading one of my workstations, with running Comsol as its primary goal. I'm considering two options (mainly): both are single CPU computers 1) with an AMD Ryzen™ Threadripper™ PRO 7975WX (4.0 GHz, up to 5.3 GHz w/Boost, 128 MB L3 cache, 32 cores, 350W) 2) with an Intel® Xeon® w7-3565X Processor (2.5 GHz, up to 4.8 GHz w/Boost, 32 core, 335 W)

In both cases I aim to 8x16Gb, following Comsol's recommendation of having all memory channels populated.

Would you have any suggestions? Should I go for a different architecture? My workstations today have two CPU, 8 and 16 cores each respectively, and relatively slow Xeon processors. I lean towards the Ryzen because of the higher clock, would you concur? I would expect any of the computers above to be significantly faster/more capable than the best I currently use (2 Xeon Gold 5218 processors, 16 cores each, 2.3 GHz speed). Would that be your expectation too?

Bests, and thank you for your help...

Javier

PS. Comsol does not make much use of GPUs yet, right? And it does not make use of hyperthreading, as I seem to remember?

Hi Javier,

first, this is not the COMSOL support, it is the forum.

Regarding CPUs, I think the XEONs are of interest in dual (or more) CPU boards with much more memory than 128 GB. Your best choice depends on the type of models too. In my case I have many time-dependent models. In my case clock frequency is very important, because this type of models cannot be parallelized. So, for my case I would go for the AMD. If you are doing models that can be parallelized you may prefer multiple CPUs and more memory. I think a single CPU XEON is never a good choice.

Maybe others have different experience.

Cheers Edgar
