New build for Cinema 4D + Redshift (GPU Rendering)

[Larry4D]

Hey guys,

 

This is my first post on the forum, so after a quick glance at the rules I think I'm all good but apologies incase I make any faux pauxs!

 

I'm a heavy 3DS Max user, I usually use either V-ray or Corona Renderer but I'm looking at making the move over to Cinema 4D, and with that I also have researched new rendering engines whilst I'm at it. Redshift renderer has really stood out to me, and playing with the demo versions for the last month I feel comfortable on taking the leap. As you may not know, it's a GPU renderer, so with my new build I'm just going to throw as much GPU power as I can at it. A lot of my workflow can be sped up with much faster previews so I can make iterations faster. I also currently heavily rely on cloud rendering services such as Rebusfarm and whilst they are great, I'm hoping to do some more local rendering whilst I'm at it. My current build will be converted to a server on the network to help even more.

 

With that out of the way, here's what I've currently spec'd up:

 

CPU: AMD Ryzen 3900X

 

GPU: 3x Asus GeForce RTX 2080 DUAL OC 8GB GDDR6 Graphics Card (3 cards in total!)

 

Memory: 2x Corsair Dominator Platinum RGB 32GB (2 x 16GB) DDR4 3200MHz C16 Memory Kit (64gb in total)

 

Storage: I would like to have at least 1 Samsung 970 EVO Plus V-NAND M.2 1TB SSD and...

2 x Samsung 860 Evo 500GB SSD

 

PSU: Corsair RM1000x High Performance Power Supply

 

So you're probably thinking, what motherboard am I going to get? Well actually that's my question to you guys. Could anyone suggest a motherboard that would make the most of the 3 GPUS? All I can find at the moment are motherboards that with multiple GPUs that limit their PCI slots to 4x4x4. Now it may not be possible to have an (16x16x16) configuration but the closest I can get would be great.

 

I used to be heavily involved in PC builds back a good few years ago but as I've got busier with work I've definitely let my current knowledge slip and I'm out of the loop at the moment. Some things like the ram I haven't thoroughly researched so I welcome any other suggestions. I'm also not glued to AMD so if there's an Intel solution I'm all ears.

 

Budget wise I'm looking at ~£3500 (excluding VAT as I can get that back) but I'm flexible. 

 

Would very much appreciate your guys thoughts. Thanks!

so something like this

 

its including 3 GPUs now, but you can add a 4th one. pcp didnt like me adding more than 2 GPUs, so the price you see on the one GPU is just the price of 3 added together. 

 

or if you dont mind some jank. you can increase that to 6 running in 8x mode. 

 

now there is one level above that, and that would be 12 running in 4x mode.

Thanks very much - I love the idea of being able to add more GPUs in the future. So with TR4, does that allow the faster PCI speeds? It doesn't appear to be as fast as the 3900x but I could maybe go for a faster threadripper?

 

Thanks again.

if you want PCIe 4.0 (which isnt all that importent yet) then you would need for Threadripper 3000 comming at some point in the "near" future. x399 really isnt made for PCIe 4.0

Sorry I think I meant, if I was using the 3900x I take it there isn't a motherboard that would support the 16x16 and 8x8 speeds of multiple GPUs?

The 3900x does not provide enough lanes for that to be possible.

 

The 3900x has 24 lanes

 

16 goes to PCIe slots

4 goes to m.2

4 goes to chipset.

 

The chipset has another 20, where 4 goes to CPU and 8 to ports and 8 are configurable. 

 

Less certain about the exact layout of chipset lanes, but i think thats how it is. 

 

In other words, there are no mobos.

 

If you want that many GPUs, HEDT threadripper is the way to go.

Ah great, thanks for explaining that one! Threadripper is the way I'll go then, more GPUs the better! I might go for the 2950X as it's a bit faster, I take it that should still be okay?

That would still be okay, but if you need CPU performance, wait for 3rd gen threadripper. 

 

If you dont need cores just get the 12 core instead

Hopefully it's not too long until it comes out haha, I have a bunch of jobs coming in at the end of September that this build would be really useful for.

 

Once again thanks for your help, definitely feel more confident with this.

Unlikely to be before the end of the year. So just buy now then. . Just upgrade if you should ever need it.
