Help deciding what CPU

[Sagecrumpton]

So I am building a editing rig that will be doing 4k 1200 fps and 8k 60 fps footage on Adobe after effects and 3D animation and design in blender and animate as well as fluid and wind simulations in SOLIDWORKS I would like to be able to screen capture while editing I just need help choosing the CPU and GPU I am pretty much stuck with quattros because of the workload that I'm doing otherwise it would be a no-brainer to go with a 3090 or 3080 I am also planning on splitting the resources between multiple users I was also wondering if it would be worth water cooling the workstation will be in relatively high ambient temperatures around 80° f to 95° f my budget is about 5,500 and anything would be a upgrade from what I have now which is a fire waiting to happen it's a 2015 Mac pro 2.2 with bulging batteries one bad fan and a broken screen well here is the build and the CPUs and GPUs I had in mind

 

2x 2 tb Samsung 970 Evo pro raid 0

1x Sabrent Rocket Q 8TB

4X 12tb EXOS drives in a USB C enclosure running raid 0 already have

4x 16 tb EXOS drives in off site backup running Linux server already have

4x 16gb cl16 3200 from G skill

850w gold plus power supply from Corsair

2x quattro p4000 or p6000 not in SLI

Corsair 5000D air flow

A noctua double Tower cooler for the matching CPU

 

i9 1900k. Cheapest but maybe not enough CPU cores and possibly lacking PCI Express lanes

MSI Z490-A PRO

 

Ryzen 9 5950x enough CPU cores but still lacking PCI Express lanes and the slightly higher boost clock frequency

X570 AORUS ELITE

 

Threadripper 3950x enough PCI Express Lanes but lacking on clock speed and has an ideal core count and I like the upgradability

TRX40 Creator. 

or wait for next gen Ryzen Threadripper 

 

I may also look at older xenon servers that I can throw the GPU's in something like this

Dell PowerEdge R720 Server 3.30Ghz 16-Core 288GB 3X New 1TB SSD 13x 1TB H710P it is the cheapest option and the noise that it makes won't be a problem because it'll be in another room but fitting those graphics cards might be a problem

I would have to get an adapter to be able to use the NVMe drives and the memory speed and CPU speed I see being a bottleneck what are your thoughts

new threadrippers are on their way and Intel's Alderlake is gonna be launching soon

Maybe wait a little bit to see Intel's 12900K or Next-Gen Threadrippers

You have a few options.

 

1. Get the 5950X (11900k is a joke, even 10900k is better in multi tasking), and try to get around PCIe lanes number by using Gen 4 drives, like Sabrenet rocket 4 plus. It will have same speed as 2 970evo in raid 0. In that case you should have just enough PCIe lanes for all the drives if you run quadros at x8 lanes, which shouldn't matter too much. Upgradeability will be an issue tho. Preferable option if you can't wait, don't need quad-channel memory or so many PCIe lanes.

 

2. Get Threadripper now. PCIe lanes are not an issue. Has more cores, but does also have lower clock speed, and Zen 2 has worse IPC. I'm not really sure after effects can use that many cores tho. It does have 4-channel memory as as well. Zen 3 Epyc is also an option some people use, they have relatively high clock and Zen 3 IPC improvements. Preferable option if you can't wait and 5950X is not enough. Also a much better option than old Xeons, and you can afford it, so don't go used.

 

3. Wait for Zen 3 Threadripper. You get the IPC improvements of Zen 3, and enough PCIe lanes. Apparently they will be released in november, but that's just rumours. Preferable option if you can wait.

For a 5950X build, consider 2x32GB DDR4-3609 CL16 memory. The 32GB modules allow for a memory upgrade should it ever be desired. Better speed and timings improve performance, especially with memory intensive work.

 

I'm not a fan of RAID 0. It can be fragile. 4TB and 8TB NVMe drives are available, so using a RAID 0 array is not necessary. If speed is the goal, use a PCIe 4.0 NVMe drive as @Ydfhlx has suggested.
