Hi
have tested few GPUs to see what is the best card for reconstructions. Test was run on 69 18 Mpix photos of the Hrusov Castle on my Dual Xeon E5- 2680- 2,7 Ghz @3.05 Ghz with Normal Q reconstruction. this are the DEPHT map reconstruction stage times, not whole meshing times. Would be interesting to see results from some hi frequency CPU like i7-4770k with same cards.
Nvidia GTX 560Ti -12m:14sec
Nvidia GTX 680 -8m:20sec
Nvidia GTX 680x2 -5m:15sec
Nvidia GTX 980 -4m:39sec
Nvidia GTX 680 + 980 -5m:35s - so mixing different architectures is not the best way to speedup the process…
