I’m considering Building a new computer pix4d Use. I’m wondering what metrics of the graphics card are most important for Processing? Is it cuda cores? Is it tensor cores? Is it retracing cores? Is it the speed of the video RAM?
There is a very wide range in pricing. It’s easy to go out and buy the highest rated gaming card, but I don’t want to buy capability that I won’t use.
Any suggestions for the components or metrics I should be focused on?

We always focused on the number of the cuda cores per € (or $). But please keep in mind its not the GPU alone. Without Cuda you cannot run PIX4Dmatic (afaik), but CUDA alone (or lets say your GPU alone) isn’t doing the whole job. I would suggest a fast processor, 128 GB Ram and a SSD Drive for the calculations.
I also remember seeing some articles online about a photogrammetry PC, maybe you can learn from these presets.
On the other hand I would like to know how PIX4D team is answering your question:
What to look out for, when planning a new PIX4Dmatic workstation? Mainly GPU? Or CPU? or SSD storage? or all? Thanks! @Rhea_Garratt @Pierangelo_Rothenbuhler @Gregoire_Krahenbuhl
Thank you for the reply.
I have now built a luggable workstation built around an Intel Ultra 9 285K, 96GB of Ram, SSD storage, and a GeForce RTX 4070 Ti Super graphics card. I bought that specific card guessing at the graphics pipeline. I am glad I did, but in truth I see the card only involved in about 10% of the time. In the case of the current Pix4DFields, it seems the CPU and SSD are far more important.
Re: the Pix4D team - Everyone is really fantastic. Super-fast during the weekdays, empathetic, accurate, and helpful. This particular question has lagged, and I likely over-spent on my graphics card because of the lack of useful and specific guidance (and not helped by the lack supply issues occurring right after the rollout of the 5-series chips!). It’s not the end of the world and I have a card capable of supporting whatever future enhancements may be provided in 'fields.

The hardware question is quite tricky and I’m sorry we weren’t able to address this specific question in more detail in a timely way. We do have a “recommended hardware” for PIX4Dmatic (Recommended hardware - PIX4Dmatic) or PIX4Dfields (Computer requirements - PIX4Dfields) , but I assume that you’d like to go into more detail.
What we’re looking at would be to have a company such as Puget Systems, that builds custom computers, benchmark our products on different configurations, so that we have more relevant and detailed information to share. They have access to all the new hardware. The more people write them about it, the easier it should become that we can setup some official benchmarking: https://www.pugetsystems.com/
It seems like you’re well equipped for any further improvements in relation to the GPU usage @mbahr4816.
Thank you for the further information, and thank you for responding to the question!
Thank you for looking after this forum now and taking care of moderating and answering our users’ questions. Sometimes it seems a bit deserted when there is no response for months. I very much welcome your commitment!
