Best hardware for tyflow?

My current 4930k cpu is getting a bit old and have been thinking of upgrading for awhile now. I am curious about which type of hardware is favored by tyflow, perhaps someone can shed some light on a few things.

Does tyflow prefer higher clock speeds or more cores? (both?)
How much of an affect does ram speed have on the simulation?
Does quad channel ram affect simulation times much?
Does tyflow use the gpu for anything other than physics calculations? Will a faster GPU help with simulations?

I have been looking at the new ryzen 3950x with 64gb ram and using my old gtx 1080 gpu. Does anyone have this cpu and what type of performance are you getting on it in tyflow? The thread rippers are also looking really awesome and they support quad channel ram, but you basically need to sell a kidney in order to afford it.

Did you complete this build or get any info on your inquiry Shadowkiller?

I'm resurrecting this thread because it is the only one I am finding with a similar question to mine.

I will add is that my Threadripper 2990wx 2nd gen is extremely slow to sim within Tyflow. This has been explained (By Tyson himself) as it doesn't have Non uniform memory access due to how many chiplets there are and there are 2 different memory controllers to access 128 gb via 8 dimms.

This creates massive lag if a cpu process expands beyond one of the 4 Numa nodes. You can limit the 3dsmax/Tyflow process to one Numa node and thus 8c ore(16 threads) but it is still quite slow - and then you are only rendering with 1/4 your cpu.

Similar to you - my old workstation is a i7 3930k and it is about 4x faster during all Tyflow sims and I want something that works faster for sims and comping in AE. My threadripper 2990wx is terrible at those 2 things so I am very curious how the 3950x fares - looking to sidegrade for the lower tdp, faster sims, and improved workflow.

Thanks for any help or info!
I have a 1950x, 2970wx and a 3960x. There is a substantial difference in performance i think, its completely subjective. I think the memory access speeds and latency has been greatly improved in the latest generation. The bottleneck apparently has been being able to feed all the cores with the data they need from memory.

A few times when simulating with tyflow i have noticed on the 2970 that its not utilizing all the cores at 100%. I recon this is because the cores are waiting for memory access. This it not happening on the 3960 as far as i have noticed. Its flying _crazy_ fast.
