In the For-What-its-Worth category, I'm running an i7 8750 with a Nvidia 1070 and 32 G RAM. I regularly see my CPU and GPU at or near 100% on the task manager while running reproductions. My RAM rarely goes above 30%. I'm processing about a gigapixel an hour with this machine,

It's been a while since I build a PC, so the following might be a dumb question.

If I understand what you wrote correctly it would be more worthwhile going for a CPU with a core clock speed of around 3.5-3.6 GHz and 6-8 cores or even an I5 with 4 cores?

From what I can see on the benchmarks the 2080 TI performs nicely, and it might be more justifiable than going for the Titan.

The thing that is eating a lot of time at the moment is the production, is production time mostly dertermined by the amount of availible RAM, and if so do you have any recomendations to which type to go for? Besides having 64 GB instead of 32.

PS. Thank you for your reply :)

Hi Jan,

I think its always going to be more cost effective to go the 1080TI route (or perhaps the new 2080 TI, though I havent tested one myself) than the titan route. The titan is much more expensive for not much more performance.

I think its also worth mentioning that for CC having a fast clock speed can greatly aid the reconstruction speed more than having lots of cores. Many cores will make the aerotriangulation phase faster, but often the reconstruction is where more time will be spent on a project.

Thank you for the Reply Mathieu. I'm currently looking at what options are availible for graphics cards on the market at the moment. Do you have any information about what would be a smart choice since there is an update comming out to CC soon (at least I think there is?), in the CC user guide it's recommended:
("As of July 2017, the following configuration is recommended: a recent desktop computer running under Microsoft Windows 7/8/10 Professional 64-bit with at least 16 GB of RAM, an 8-core CPU and an NVIDIA GeForce GTX 1080 Ti graphics card. Please contact the technical support team to design more powerful configurations (GeForce GTX TITAN, Quadro, bi-Xeon, etc.).)"

I'm just wondering what the recomendations would be now, and if I opt in for something less pricy than a 3000€ Titan card would it be insufficient to last me through the next updates to CC over the next few years?

Hi Jan,

Both ContextCapture and LumenRT will benefit from an high end video card with powerful GPU and lot of video card RAM as both use heavily the GPU.

So I think you should invest on the GPU but not so much on the CPU side.

HTH,

Mathieu
