Hardware specs for TBC and other pointcloud software

Post by matosk »

Hi all!

I'm a GIS-engineer from Sweden, relatively unexperienced in pointcloud-processing. We´re in search of new more powerful computers to be able to work with more flow and efficiency. We've been offered computers with the following specs (see attached file).

Now, would you say these specs are ok, good or very good for e.g Trimble Business Center, Cloud Compare etc.?
I guess the RAM is really important and that 32GB is minimum?

What about the GPU and the CPU? Any thoughts?

Best regards,

Mattias

Depends how big the point clouds are but I tend to think of 64gb as basic spec for RAM on new PCs at this stage. On the Z2, the i9 12900 CPU is a couple of generations old at this point and the A4500 GPU is lower performance than the RTX4070 while costing more. Depends very much on price, but that HP Z2 would not be my first choice for point cloud processing.

Hi Matosk

To address how that build would suit for TBC specifically, The processor and graphics would be Very good or Excellent.
(I have a feeling that 20GB graphics card is probably overkill for TBC itself, but sure this would have value elsewhere)
As mentioned RAM is important and agreed 64GB is minimum if you're trying to do big point cloud work.
Swapping out some of the graphics card cost for 128GB RAM might be worth considering.

Trimble have documents for TBC that break down how different processes use different components of PC.
The general advice is "aim for a good balance, with no weak link. High CPU speed is preffered to massive core count, and don't need a massive graphics card"
I can't share document here as its marked confidential, but if you contact your local dealer or PM me i can discuss it.
