I have been watching this thread and decided a couple weeks ago to build a ryzen pc. Here is a little background. I bought a eBee SQ this past winter and I built an Intel core i7 computer with the following specs.
Intel Core i7 6700k overclocked to 4.2Ghz
32 GB Ram running at 3200
512GB m.2 SSD – Samsung 950 Pro
Nvidia 1070 with 6GB Ram
Two 4TB Spinning drives in raid 1 for data backup
Windows 10 Pro
I have been using this machine all summer learning and gathering data for my ag drone business that we will be working our way into next year. While this machine was working well and comparing processing speeds to my dealer’s laptop speed I was feeling happy.
With all the hype around ryzen and specifically the lower cost over Intel’s 8 core offerings I decided to build the fastest machine I could based on the 1800x.
Here is what I built.
AMD Ryzen 1800x overclocked to 3.9Ghz
32GB Ram running at 2400
256GB m.2 SSD – Samsung 960 Evo
Nvidia 1080Ti
Windows 10 Pro
I built the machine and started testing out the speeds rendering three different projects. I Testing the following different configurations.
Intel 6700k with no GPU
Intel 6700K with 1070
Intel 6700k with 1080ti
AMD 1800x with 1070
AMD 1800x with 1080ti
The three projects were as follows.
Project Name: Timber 2
Images: 1072
Keypoints: 10,000
Project Name: Leos
Images: 4564
Keypoints: 500,000
Project Name: Darwin Home
Images: 3756
Keypoints: 500,000
The projects Leos and Darwin Home were later in the season are both 120 acre fields that were flown at 85% overlap.
Here are the results that I gathered from the reports that pix4d produced. I put all this info into a spreadsheet and I will just give you the results of my findings. The numbers are the seconds to run thru steps 1, 2 and 3.

My conclusion is that the AMD 1080x was faster on smaller projects with less images where stitching was easier. When I got into the larger projects where I had to up the keypoints to make the image stitch without leaving gaps the 1080ti made the biggest difference in speed.
My feeling is the slightly higher clock of the 6700k and the overclocked ram helps a little with the speed difference. I am now watching the new i9 processors as they will run at a turbo boost level equal the newer 7700k when full processing speed is not needed then back down a little when all cores are utilized.
I ended up keeping the 1080ti in my Intel machine and disassembled the ryzen pc and returned all the parts. I will probably build a i9 setup this next spring before we get back into the fields.
If you have any questions please feel free to ask. Hope this helps someone.
