Hi,
Sorry for being slow to report on the eventual results.
I appreciate all the help and discussion feedback.
We ended up building a few computers with 3900X CPUs, each with 64 GB of RAM. We did this before e.g. the 3950X was released, so we never considered using that CPU.
RAM turned out...
Hi,
Update: Due to output of stock etc and trying to keep to one supplier, I'm tomorrow planning on ordering the build shown below.
I ended up going with a non-budget SSD, and also an X570 motherboard because it was in stock (and not to pricey actually).
Picking the case was the most difficult...
Ok, seems reasonable now.
Thanks for the BB tip.
I put together a wallet friendly option using the 3800X below.
To me it's surprising, and almost ridiculously so, how well my rough performance estimate match the estimated prices.
4 x Ryzen 3900X at 15 kSEK each = 60 kSEK, and 4 x 12 x 3.8 =...
Given what I just explained in my other reply, this is actually quite interesting. Especially given that the 3900X is currently out of stock everywhere.
But.. is the performance really only 20% lower?
Looking at power/cores/base clock, and as tasks will run for several hours, I thought I could...
I appreciate the tip regarding four DIMM slots btw. I am considering the importance of future upgrade-ability, although that's just making it more difficult for me to decide, but see my remark at the end. :-/
Regarding RAM use: I budgeted 2 GB for the OS etc, leaving (32-2)/12 = 2.5 GB/core...
Regarding PSU, why "platinum or titanium"?
Environmentally friendly to waste less, or is there some added benefit when running the CPU for long periods?
Thanks for the tip about 2 CPU connectors, I hadn't thought about that.
Regarding SSD: One simulation is perhaps 5-10 minutes, producing perhaps 1 GB of data.
So the SSD ought to be able to save that in less than a second. Therefore I expect a PCI 4.0 on the x570 to not really do much for that...
Hi, I'd like some inputs on a computer build I'm going to do.
1. Typical tasks:
Running batches with hundreds of simulations that use the CPU, i.e. not the graphics card. The software is MATLAB/Simulink if anyone wonders. A batch run could take 8-12 hours, so temporary CPU boost doesn't really...
