Work pc for rendering

[adey]

Hi

A friend of mine who builds TV sets and models etc has decided to go freelance. He’s asked me to put together a pc for him, his bread and butter program is rhino 6. Now I’m taking it he’s going to need as many cores CPU wise as possible so ryzen seems favourite, it’s the GPU I’m not sure about. His old machine was an old intel xeon with a quadro GPU.

So if anyone with any rendering experience could help me spec a tower only for around £1000 I would be very grateful.

Reading up about rhino, it's not massively parallel, so more CPU cores != More performance ... So higher clock speed would matter more.

GPU wise is different apparently. Bigger does equal better for rendering (complexity depending). More vram and more GPU cores increases the render speed.

Also some have commented on fast storage too.

Great that gives me something to work on, decent size SSD seems a must.

Rhino 6 is much more multi-core aware than Rhino 5 was, and from a pure price to performance ratio the CPU to be looking at would be the new Ryzen 9 3900XT, along with 64GB DDR4 3200/3600MHz RAM, and a decent X570 board with a couple of decent NVMe drives, one for the host O/S and the other to run Rhino with.

You'll probably want to spend more than £1000 over all, and could go with 32GB RAM to start with as that is easy to upgrade, also the GPU side of things doesn't effect the rendering only the animation (panning/rotating/zooming) of the on screen of the models, which can be the most work for some peoples workflow, and others are happy with slower rendering, so a lower end CPU. Maybe look at something like a 5700XT or RTX 2070 Super, you could go lower if the work flow isn't as demanding from the modelling perspective, e.g. not doing complex operation like trim and fillet on 1000's of holes at a time.

Lots of things to consider really, does the person make a living from the machine? I assume yes from the first post.

He will be, he's going self employed very soon, and this will be his work station, I'll speak to him about the budget. He's really talented and I want to give him the best start I can.

Six cores tops, per McNeel:

Since modeling is a very serial process, there isn’t a lot that multi-threading can be used for.
In V6, we have added some multi-threading tools (like Make2D and Rendering), but you can’t effectively make use of a large number of cores. Past about 6 and the time it takes to split the job, distribute it to another core, do the calculations, and knit the results back together is a net loss.
There is nothing to be gained from having even more cores.

So a Ryzen 3600 will do just fine.

That's from 2016, before Ryzen was released and if you are rendering on the CPU (not GPU) you'll want as many cores as you can get your hands on, alongside a good chunk of RAM. When that thread was posted 6-8 core CPU's actually cost quite a lot of money, and required HEDT/Workstation machines and people focused on GPU to help keep the costs down in the consumer/prosumer desktop market.

The Ryzen 3600 will be fine as long as he isn't doing a lot of rendering on the CPU, and can off load it to a more expensive GPU.
