Question Need help/advice with heavy workstation build

[localstarlight]

I'm trying to scope out a really meaty workstation build, and would love a sense check/some advice.

We are going to be using the workstation for three main things:

1. Houdini sims (flip/pyro mainly)
2. Redshift rendering
3. Unreal Engine development

Here are the current specs of the proposed build:

• Mobo: ASUS PRO WS W790-ACE
• GPUs: ASUS 4090 x 2
• RAM: Samsung 32GB 4800 MHz ECC DDR5 Server/Workstation RAM x 8 (256Gb RAM total)
• CPU: Intel 24 Core Xeon W7-2495X
• Drive 1: Corsair MP600 PRO XT 1TB
• Drive 2: Corsair MP600 PRO XT 2TB
• Cooler: Noctua NH-U14S DX-4677

My main questions concern the CPU:

• Is the clock speed of this Xeon going to be ok for this kind of work? Not sure how well it will play with Unreal Engine?
• Would a Threadripper be a better fit? Or something else entirely?

But also wondering if there are any other considerations here that I might be missing. All help massively appreciated!

Ah, sorry we actually do have a PSU picked out, just forgot to add it:

Corsair HXi Series 1500W 80+ Platinum Power Supply

My main concern is around the CPU for the kind of work we’re doing.

The sapphire rapids cpu pricing and 3000 series threadripper pricing looks to be similar.

Intel usually have their CPU software verified or have better support. So i guess going intel here would be the right move...

You can likely get similar performance SSDs from another company for a large amount of savings. An example for 1tb and for 2tb drives.
