Computer hardware - is it a good configuration?

Don’t know if it’s ok to ask here, but would love some comments on the computer setup I plan to buy (admin please move if in wrong thread):

  • CPU Intel I7 8700K Coffe Lake
  • Cooler Corsair H110i liquid cooler
  • ASUS Nvidia Gforce GTX1080Ti 11Gb Gaming OC
  • RAM: 64Gb (4x16Gb Corsair 3000Mhz DDR4)
  • Motherboard: Gigabyte Z370 AORUS Gaming 7
  • Hard disc: Kingston KC400, SSD 512Gb
  • Power supply: 1000W
  • Two 27" IPS monitors

What can I expect of this configuration? Would 3D modelling with cca 1000 pictures take some reasonable time?

Hi Dario,

 

Processing time does not depend only on the hardware configuration but also on the processing options used and the dataset, which is defined mostly by the number of images of your project, the resolution of the images and how many features are found in the image. Also depending on what you want to reconstruct, which results you want to obtain, how accurate, etc. there are several factors to consider.

Since the processing depends on many parameters, it is hard to estimate the processing time, and there is no formula to calculate it precisely. 

With the following hardware configuration, using Windows 7 64Bits, 67 images at 14MP and the default processing option:
CPU: Intel® Core™ i7-4930K CPU @ 3.40GHz
RAM: 48GB
GPU: NVIDIA GeForce GTX 660

you should expect about:
Step 1 Initial processing: 5min
Step 2 Point cloud densification (without 3D mesh): 20min
Step 3 Orthomosaic: 35min

Please note again that with a different project but the same number of images, with the same computer configuration you could obtain different processing time. For example, the image content effects on the processing time. The more keypoints are found on the images, the more time it will take.

I believe the following posts can bring you more insight into benchmark assessment and processing time:

Hi Ina,

thank you for your answer.

I know that the processing time depends on the “complete picture”, not only on hardware.

As I wrote, I need someone experienced in building up computers that will work well with Pix4D to give some suggestions.

Of course if you take such a small project like you said, with 67 medium pictures, it will take a minor time to process and the differences in HW configuration won’t make any difference.

But if you take a combined 3D indooor and outdoor project, with 2000+ 24Mp TIFFs, with lot’s of details and overlap, with a huge amount oh MTP’s, every HW component plays a huge role. Even if the processor is water cooled or not :slight_smile:

As I did not get any answer from this forum, I asked the same question at the Fb Pix4D users group and got some great answers.

 

Best,

Dario F.

Hi Darion,

 

I am always impressed on how our users network :slight_smile:

Could you share the inputs here so that other users will benefit from them?

 

Thanks,

Ina
