Discussion Overview

The discussion revolves around building a computer optimized for Finite Element Analysis (FEA), focusing on the choice between AMD and Intel processors, as well as the role of graphics cards in enhancing computational power for FEA tasks. Participants explore hardware options within a specified budget, considering both CPU and GPU capabilities.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Exploratory

Main Points Raised

  • One participant is considering the Ryzen 9 5950x for its performance in FEA, despite its high cost, and is open to suggestions for alternatives.
  • Another participant questions whether a graphics card can enhance FEA performance, suggesting that FEA may be run on a GPU.
  • Some participants argue that Intel and AMD CPUs are generally similar for general purposes, with processor speed being a more critical factor than brand.
  • There is a discussion about the potential benefits of a better graphics card, with one participant noting that some software can leverage GPU power for simulations.
  • Concerns are raised about the compatibility of consumer GPUs with professional software, highlighting that many packages may require specific hardware like NVIDIA Quadro for optimal performance.
  • It is noted that while some software can utilize GPUs for certain tasks, it may not necessarily speed up the core calculations, emphasizing the need to understand software specifications regarding GPU acceleration.

Areas of Agreement / Disagreement

Participants express differing opinions on the importance of CPU brand versus speed, and there is no consensus on the best GPU for FEA applications, as well as the extent to which GPUs can enhance performance in specific software packages.

Contextual Notes

Limitations include the lack of clarity on which specific software packages are being discussed and their respective capabilities regarding GPU acceleration. There is also uncertainty about the exact performance differences between the suggested CPUs and the implications of using consumer versus professional GPUs.

TL;DR
I'm building a computer that I'll be using for FEA
I'm building a computer that I'll be using primarily for FEA. No games. I'm leaning towards the Ryzen 9 5950x. I have a budget up to $1000-ish +200 maybe for the CPU. That will hurt seeing how I'm considering a $750 CPU (5950x), but I'd be willing to if need be and the gain is significant. Unless someone has other suggestions? The threadripper in that range that I've found is the 2970WX. Any suggestions are greatly appreciated.

Can your graphics card add more power to your design ie can FEA be run on a graphics card?
 
Intel and AMD are very similar general purpose CPUs so it shouldn't make any difference. What's likely to be more important is processor speed.

As @jedishrfu suggested, a GPU will give you more power if it can be made to fit your algorithms.

The software shows comparisons of how the GPU can speed up simulation so yes. I think I'll save up for a better graphics card to get more bang for my buck.
 
Just be aware that many "professional" software packages won't be able to take advantage of consumer GPUs. They are often designed so that you need something like an NVIdia Quadro for it to work, Note that it is not necessarily about the HW (consumer GPUs are often very fast), but about the drivers.

Note also, that some packages (e,g, COMSOL) will be able to use the GPU when editing etc (which is nice, especilly when working with 3D graphics); but they won;t necessarily be able to use the GPU to actually speed up the calculation,. Hence, you need to read the fine print to understand what "acceleration" actually means for the package you are using.
