Thanks for contacting us about hardware beforehand.
Are the renderings to be mostly exteriors, or also include interiors? And if interiors, do they include extensive room layouts. And for exteriors, will you be requiring to include detailed surrounding buildings or generalized in-context buildings?
To answer your specific questions:
1.) Does having Multiple Video cards help it render faster?
No. Lumion is only able to make use of the dedicated graphics card assigned to Lumion.
But, you can have a PC with multiple cards, where the other card is used for other software whilst the one assigned for Lumion is busy with a Lumion task. For example you work on some CAD design whilst doing a Lumion render.
2.) Does having 64GB make a difference?
Not generally for render times. But it does help where there are large and/or complex Scenes
and the extra memory helps with overall performance once memory has been used up on the graphics card. You will see more of this mentioned in the articles below.
3.) Do you think the Quadro P4000 is good enough? It has a 10,000 Passmark
It is OK, and the pricing is quite reasonable these days. But, as in my earlier questions, that would depend on your overall Scene
complexity. For example if you are talking about multiple skyscrapers etc.
The are probably other better options such as the GTX/RTX cards that perform much better per $ spend.
If the corporate requirement is only for a Quadro based card then the P5000 with twice the memory, and similar performance may give you a card with greater ability to handle more complex Scenes
, and avoid re-investment if project demands change.
4.) Do more cores help on the processor?
More CPU cores than 4 will not make a difference.
(see What kind of computer does Lumion need?
article as below).
Have a read through this useful overview of the key hardware requirements for Lumion: Blog article: Lumion Computer Advice for Faster 3D Rendering
The new RTX cards from NVIDIA have an approximate 20 to 30 percent gain on the GTX cards mentioned.

articles: What kind of computer does Lumion need? Which graphics card do you need?
The Intel Xeon Gold CPU has a clock rate that exceeds our recommended 4.00GHz clock rate so that is fine.
Other things to make sure of for the PC are a good high quality power supply. We also have an article about those linked in the above articles.
I would suggest more than a single SSD drive. You need at least a 2TB extra drive for project and Scene
files, depending on what the storage networking arrangement is in the organisation. The Lumion LS files can range up to 5GB per Scene
, so plenty of storage (which is very affordable) is always worthwhile.
You can choose a workstation based PC (one with a Quadro/Xeon) or a general 'gaming' based PC (one with a GTX/RTX or AMD Radeon, and Intel Core CPU) card, or a mix if you want. GTX/RTX cards work equally well with CAD based applications.
If the PC will have a primary use of creating the Scene
, and then doing the rendering, then a brand name (such as Dell) with GTX/RTX cards will offer a better price performance.
Working through the requirements for hardware can be quite involved sometimes. So let us know if there's anything else we can provide guidance on.
