SFX simulations, Adobe After Effects and video editing. I have 96GB in my workstation now and I have to be careful, especially with fluid sims because I was constantly crashing with 64GB. After Effects gets faster as you throw more RAM at it and a great deal of my animation will involve soft body simulation so I will need as many cores as I can round up. Then there is Arnold. It eats cores for breakfast, but I guess only a render farm can satisfy that. 128GB and more are common in workstations used for animation production. I can hold 512GB in my current system (and I will be filling her up as I go along). She will need a sister soon and I want her to at least be able to carry 128GB.

Well, honestly for your case, you should probably just wait for the 3000 series Threadriper or Epyc CPUs to come out and build a new workstation. This will allow you to get larger amounts of RAM using lower volume sticks that are clocked faster. (and if you go with an Epyc platform you will also have the option to run ECC RAM)
Epyc is way too expensive and the clock speeds are too slow. I'm looking to build something with a high core count and higher clock speeds than 2.1Ghz base. I would love to have a Threadripper, but I would have to compromise on single core performance like my current workstation. 16 cores, topping out at 4.3 - 4.7 Ghz is my sweet spot for a dual-purpose machine. And the price of these new Ryzens are hard to pass up.
I still need gobs of system ram regardless of the video editor and Physx has a long way to go. Only useful for games at this point, at least for my project. GPU technology will get there one day, but right now it is in its infancy.
Found the 128GB boards! https://www.tomshardware.com/news/gigabyte-aorus-x570-ryzen_3000-motherboards,39504.html This makes me so happy. I get to buy a new workstation for a change. I imagine the reason for the 64GB limit on so many high end boards is market segmentation. AMD marketing department knows what it is doing. If I can get a high powered 16 core Ryzen 3750 with 128GB, it would rob some market share from their low-end HEDT Threadrippers. So the TR 3 will probably start at 24 cores to keep it ahead.
In fact there is no real memory limitation on motherboards. The official memory limitation always comes from the biggest memory module at the time. For previous generation it was 16GB and 4x16=64GB
Now that 32GB modules are available it is unlikely that any manufacturer will test them on old boards and only new boards will eventually have an official support for these (and it's a selling argument) but these may work on old x370 or x470 board too
Some people succeeded in having 128GB RAM on some x370 or x470 board, but with ECC UDIMM memory.
That's the good thing with AMD : you can use UDIMM memory which usually have higher capacity but are clocked lower. You just have to check the motherboard manufacturer if ECC is supported. ASUS and ASRock boards usually do support ECC memory
Just gonna jump in here for a sec with a couple of thoughts.
For rendering, PCIe 4 bandwidth isn't going to matter all that much.
Wendell at Level 1 techs was pretty proud of himself when he slapped a 3900X into a B450 MSI Tomahawk, which is a very reasonably priced board. He was able to get 64GB of ram running with the 3900X on that board, and he says it's been running like a champ.
This may be good news for those of you looking to do a drop in replacement for your existing AM4 board, depending on which board you have. A number of 400 series boards and some 300 series boards have BIOS updates for the new chips, but not all of them.
For those of you wondering if there's an AM4 board out there that has 4 PCIe 16 (i.e. full length) slots, there is.. The MSI X570 Godlike. It's pricey, though, $699 US.
https://www.msi.com/Motherboard/MEG-X570-GODLIKE.html
BTW, the X570 Godlike supports 128GB of ram.
Using all four full length slots will drop you to x8/x4/x4/x4, but that should be plenty fine for those looking to do something crazy like installing four graphics cards for rendering, assuming that the board can handle four graphics cards. At $699 though, a Threadripper setup might be the better way to go. 7nm Threadrippers aren't due for a while yet, and we don't have a firm release date for those as of this post, but they eventually will be options...
The existing Threadrippers have been dropping in price in response to the Ryzen 3000 launch, so you may be able to find some pretty sweet deals on these CPUs.
That said, yeah the 3900X is an awesome value for 12 core CPU rendering. the 3950X is coming later this year, in September, with 16 cores.
...likewise, I also use Carrara as well as 3DL (with Wowie's aweShader), so CPU core count is important. The nice thing is I have two networked systems and Carrara supports networked rendering (wish Daz did as well).
if i quit buying all this DAZ stuff I could afford a system that would render it all.
I'm seeing some X570 mainboards around 200 bucks. Not too bad. RAM seems rather expensive at the moment? I'm looking at DDR4-3200, is that even the right one?
RAM is really cheap right now actually. It should go down further through the rest of the year but how much isn't known.
3200 or 3600 is what you want ideally. If you need to save a fewbuck go down to 3000 or lower.
UPDATE: Well, good news bad news... CyberPowerPC, and most vendors I'd imagine, are already backlogged on the 3900X. So it'll be a few weeks, instead of Friday that I receive the system. The good news is that they've updated their site and now support 64GB of RAM and they've also added 3200mhz support (board supports 128GB / 3200mhz before overclock, I believe). So this will be even beefier, but will take a few weeks to arrive. Thanks again for all the guidance
PCIe 4.0 might not effect GPUs...yet, but that could change. The extra bandwidth could open up new opportunities we have not thought about yet, like new forms of NvLink that do not need the connector. Using multiple GPUs for rendering could perhaps see a boost if properly taken advantage of, even if they are not the same chip like NvLink requires.
Lots of cores means you can have more stuff going on, provided you have the memory. Multitask like a champ, even while you render. And a lot of programs are taking advantage of these cores as well. Compression software like 7zip, Adobe Aftereffects, Blender, just to name a few. So while Daz Studio does not take much advantage of the extra cores, a lot of other creation software you probably use will benefit greatly.
Here is a nice in depth review of the 3900X and 3800X. The first half deals with a variety of creation software.
I saw a rumor about the next Intel lineup. If true the top Intel chip will have 10 cores, instead of 8 like the 9900K. But here is the kicker, once again the new chips would need a new motherboard. Surprise! LOL. So if you bought a 9900K today and wanted to upgrade, whelp, you gotta buy a new motherboard as well. But Ryzen is not like this. If you buy a 3900X today, and next year AMD releases newer even better ones, hey, you can just drop that new chip into your current motherboard. I can't stress enough how much that saves you. Not only do you save a decent amount of cash for not buying a new motherboard, but also time since you need to reinstall everything PLUS activate Windows. if you use Windows.

guys Ryzen 3900x its work for Iray render on daz?
On passmark ryzen is on pair at single core and much better with multithreading, you will get benefits both with 3delight and embree and any multithreaded 3d package around such as blender or maya. As for daz studio it is fine with 4 cores so if you only use daz studio with iray you may want to get a cheaper cpu to save for a better nvidia card.
Any CPU that works with Windows 10 will work with Studio, which is what I presume you mean (well, it also shouldn't be too old or low spec). Not aware of Daz needing any CPUs, who are the company and have more than one product.
It's a CPU not a GPU. To get GPU acceleration in iRay you need a Nvidia GPU.
