GPU recomendation and experience with Radeon 5700 XT

[Mario]

Does anyone have experience with Radeon 5700 XT?

I plan to upgrade my GPU and my options are:

1. 1 x 980 Ti or maybe even 2  980 Ti (I have found used for 190 euros for one card. Cards are from one seller, excellent condition, used for gaming, not mining)
2. 1 x 1070 Ti used
3. 1 x 1080 Ti also used

and
4. Radeon 5700 XT new card with warranty

I know that the most important thing for Nvidia cards is the number of CUDA cores, I assume the same goes for AMD cards.
So I expect similar processing power from 1070 Ti and 5700 XT.

The only thing that worries me is the unexpected death of used cards. I saw 980 Ti dying in front of my eyes a few days ago

my hardware is:
Ryzen 7 1700X - 8 cores
x370 motherboard
2x8 GB of RAM (I ordered 64 GB kit)
GTX 1050 Ti (4 GB) (could find anything good for a reasonable price during mining mania in begging of 2018th  , same goes for RAM)
SSD and NVMe drives

I usually process datasets containing a few hundred aerial photos from P4, but sometimes thousands of images from 4 to 20k of images in a combination with LiDAR point cloud. And really oblique photos of monuments (10 - 400 photos)

Thanks for your answers!

Mario,

Unfortunately the current RDNA based AMD GPUs (which the 5700 XT is part of) seem to have abysmal OpenCL drivers which hinder there performance. The best performing AMD consumer GPU for OpenCL based compute loads is the Radeon VII which is no longer manufactured. Your best bet IMO would be to get an Nvidia RTX Super GPU which are the best bang for buck. Unless you are willing to wait for the next round of AMD RDNA2 based GPUS coming this year (CES is in a few days so expect some early announcements)

Thanks, Mak11

I'll also look into RTX Super cards.
I have totally forgotten that these cards exist

For the budget oriented, do you think that the RTX 2060 6GB is the minimum recommended?
I also want to upgrade but I am between the RTX 2060 and the GTX 1660 Ti 6GB.
Does VRAM play major role in performance and if so in what parts? Is 6GB enough for up to 2000 20Mpx photos (DJI P4P)?
