Power PC for High resolution
« on: December 26, 2017, 09:06:17 PM »
Hello,
i would like to know if my PC can be update a bit to improve the speed in Photoscan.
Projet is between 500 to 1000 photos and i would like to get High resolution.

It seems now it takes 2 days but i would like to know if it can be in 1 day if i update my PC but not for too expensive.

Here it's mine :
Samsung Serie 960 EVO M.2 PCIe NVMe - 1 To
Intel Core i7 7820X
Asus Prime X299-A
HyperX FURY RED DDR4 2 x 16 Go 2666 MHz CAS 16
Asus GeForce GTX 1050 Ti STRIX OC - 4 Go

It seems i can change for a I9 7940X and a GTX 1080Ti but it 's a lot of money, but if i do the speed in photoscan can be very good?

is it important the CPU or GPU?

thank you

Hello Julien999,

Currently PhotoScan supports GPU utilization for the image matching and depth maps calculation stages, so if you are processing large datasets and are generating the dense clouds in at least Medium quality, then you should have at least one fast GPU that will speed up the mentioned steps.

GTX 1080Ti according to the specifications should be about 4-5 times faster than GTX 1050Ti in terms of PhotoScan performance. But you can also check less expensive cards, taking into consideration the number of CUDA cores as a main performance factor.

As for CPU, I don't think there's a need to switch to 7940X, since your CPU is already close to the optimal parameters - reasonable number of CPU cores and quite high CPU frequency.
