Revit CPU Maximum Cores for Rendering

[Anonymous]

Edit:  I am specifically targeting rendering speed on this workstation.

On the system requirements page for Revit 2019, it states:  "Autodesk Revit software products will use multiple cores for many tasks, using up to 16 cores for near-photorealistic rendering operations."

1)  I take this to mean that Revit can't and won't use more than 16 cores, so having a high-powered render station with more than 16 cores is pointless.  Is this a safe assumption?

2)  Are there any plans in upcoming versions, maybe even 2020, to raise the max cpu core count?  If I deck out a render station with the 28 cores that my motherboard supports, will they be usable soon, or am I just wasting money?

Thanks!

Actually, 99% of revit process will use only one core. Rendering only (and may be some other tasks) will use more cores.

Also in render, a fast octa core processor will be sufficient for Revit render. Unless you will use other software for render then may be you need more cores.

focus on the speed of the processor and not the number of cores. also focus on the maximum speed of your first core.

Also more RAMs will be more beneficial for modelling.Minimum 32 GB (64 is fair enough)

I recommend this processor with base speed for all cores 3.6 Ghz and the speed of one core may reach 5 Ghz

Thanks for the reply!  I realize now that I wasn't specific in my post, so I edited it to reflect that I'm definitely targeting rendering speeds on this workstation.  My client (I'm hardware support, not the end user) is rendering very complex models on an almost constant basis and wants to maximize rendering speed.

Does that change your answer at all?

No reason to go to Xeon Scalable, possibly dual cpu, or anything?  Revit just won't use them efficiently?  What if price wasn't a concern?

Rendering with revit is not the best solution for renders.

If you are rendering on 3ds max using Vray for example, the cores will make huge difference.

However, if you are using Revit+Lumion for example: the speed of the core will be the key.

I have 2 PCs:

1- have 2 Xeons with total of 24 cores/48 threads but with speed 2.2 Ghz up to 2.9 Ghz.

this one I use it for 3ds max renders. and sometimes for lumion. 

2- have i9 octa cores 3.6 up to 5.

This is my desirable for Revit and Lumion.

Based on the fact that most my work is on Revit, I prefered the option 2 which is half the price.
