Threadripper 3990x Tests

[shadowwolf]

Hi all. I know this is a long shot, but is there anyone on here who has a Threadripper 3990x that would be willing to assist me. My company is looking to buy one of these chips for some numerical modelling software, however we have not been able to find any benchmarks or performance comparisons for the software we use. If anyone on here would be willing to let us run a few benchmarks on their system that would be hugely helpful. Alternatively does anyone know a retailer/reseller who would be able to assist us with this is we were to purchase through them?

1) what software are you looking at?
1.1) how much ram do you need?
2) do you need ECC RAM?
3) Would you consider an AMD 5900 instead?

New TR is coming soon but I’d wager that the AMD 5900 would be faster than a 3900X (unless you need far more RAM and pci-e expansion)

I need the threadripper 3990x as we are running DHI's MIKE software. Our current PCs are running i9-9980xe and we are looking for something at least 2 times faster so the 5900 is not likely to be fast enough. The software heavily makes use of multi-core processors., so core count is hugely impactful.

Regarding RAM: we use between 32 and 64 gb and don't necessarily need ECC RAM.

I'd wager for their compute requirements, cache is a bigger deal as it seems they are modelling water. These models can be heavily threaded without too much performance loss. They're often memory-bound rather than compute bound, though, so I'd focus on those figures in my calculations.

@OP, have you considered GPU versions of their applications? You may find that throwing GPU into the mix can add more legs to the system.

Looking at what Messu said and the software page for Mike 21, you’d be foolish to spend money on a new CPU processing rig.

If it was my money, I would make sure that the version of Mike that you are using is able to leverage GPU performance.

there are examples on the Mike 21 site where they combined a Core i3 and a quadro graphics card to reproduce the same results (to within a rounding error of the the 6th digit) as the OpenMP use case.

for my money, I would install an Nvidia graphics card that uses ECC RAM (laptops direct has an PNY Quadro RTX6000 graphics card in stock for ZAR85 000.

I would replace the Intel rigs in the near future (think February when this whole shitstorm of computer hardware purchasing has settled down) to buy an TR 3990X with 256 gigs ECC RAM.

The reasoning behind using ECC RAM is that for your professional use case, you absolutely need accurate results rather than absolute performance.


Can you find out which version of Mike you use and if it supports Nvidia GPU acceleration?

I would get one of the resellers on here to find all of the components come Jan/Feb. You may need to pay a deposit.

That, or I would rent a server processing unit from a time being until your hardware can arrive.

You would then upload the data to the server and leverage both CPU and GPU processing as and how you need it.
