So weird! It seems Nvida GTX1080 is slower than GTX1060

I just bought two PCs for drone image processing using Pix4d. The specs of the PCs are as follows:



it's obviously that PC1 should be much faster than PC2, which is also verified by the overall performance test from a third party software.


However, it turned out PC2 is faster than PC1 when i run a test dataset (47 12M images) with same configurations with two PCs using Pix4d (see
follows).


its said the fist step is most GPU consuming. How come a slower GPU (GTX1060) works even faster than a faster one (GTX1080)? it's noted that both  GPU are upgraded to the latest driver.

Anyone come across the similar issue? ANY comments would be greatly appreciated.
