hmm dont know if I did something completely wrong here or if I used some weird setting in Agisoft..but the GTX 980 was actually slower at least when looking at the Show info for my chunk.

Pic 1 is on my machine GTX 670, 24gb ram and a xeon 3,47Ghz

Pic2 is the machine with the GTX 980, 24gb ram and a xeon 2.6 Ghz (cant remember exactly) In the open cl settings I had 2 cpu cores deactivated

Pic3 is the machine with the GTX 980, 24gb ram and a xeon 2.6 Ghz (cant remember exactly) In the open cl settings I had all except one cpu cores deactivated

This is just a scan with 18 pictures, maybe it will be much different on a larger scan.

Hello bmc130,

You need to check Device Performance lines in the Console pane right after the depth maps estimation phase. Or enable "Keep depth maps" option in PhotoScan Preferences window.

On the screenshots there's no time for the depth maps estimation and it is the only step where GPUs are used for processing.

Aha ok had no idea, so if I keep depth maps will that be showing in the show info dialog?

Ok so know I enabled Save depth maps and this are the times I got. Strange it's being slower, could it be that the computer with the 980 card have a not as good processor?

Pic1. GTX 670

Pic2. GTX 980

No thats the thing, they are not run on the same computer. This was just a quick test since one of my co workers got the card yesterday. His processor is smaller than mine.

The spec for the computer is:

Xeon x5650 2.67 Ghz, 24gb Ram, GTX 980

My computer:

Xeon w3690 3.47Ghz, 24gb Ram, GTX 670

Unfortunatly we are in full production so cant hijack his computer as much as I would like to:)

change the GPu for the speedier CPU as it deliver much faster data to the GPU.. disable ALL CPU in OpenCL benchmark.. and report back, should see much higher speed..

Just in case this may help somebody:
When I installed the new Nvidia-Driver for my GTX 675M and started PS the preference settings for OpenCL had changed. It used both the GTX 675M and the onboard Graphic HD4000 (which is only able to use Opencl ver. 4.0). After I changed the Nvidia Optimus settings for PS so that it should only use the GTX 675M it worked fine and used OpenCL ver. 4.4.

for GPU speed reference.  These cards were introduced in november of 2010... The quadro much later and supposedly superior for openCL calculations.  Don't believe the hype.  I can't wait to get 5 x 970's in this system.
