I currently have a Dell computer with a 10 core I9-10900 processor with 64GB RAM.
I occasional get a 1-2 month project where I am running NSC models with many CAD parts, tracing 1e7 rays, running several variations of the zemax file in parallel. These runs often take 2-3 hours. Sometimes I do Seq Hammer optimizations that take 17 hours. I am more often running models that take 30min w/ numerous iterations is time consuming.
I was looking at the Dell 7865 series with the AMZ Ryzen threadripper processor. I am trying to decide the following options. I am willing to spend the money on the most expensive configuration if necessary.
Also I may sell this in 1 year to get a Mac Pro w/ 64-128 cores because I need the neural processors for other applications. It is probably easier to resell a computer < $10k
I am leaning towards option 1.1.
- CPU: 32 vs 64 cores
- 32 cores. 3.7x increase speed ($9,100, 64GB RAM, Single A4000)
- 64 cores, 5.0x increase speed ($12,500, 64GB RAM, Single A4000)
- RAM: 64 vs 128GB (+1,200)
- Video Card: Single NVIDA 16GB, Single A4000 vs Dual A4000 (+ 750)
