PLEASE can someone explain to me what can cause the speed difference?
I have used 2 identical machines, (different motherboards but otherwise almost identical. One have a gtx 980Ti and the other have a 1080.
The 1080 rendered 8m2.3s and the 980Ti completed in 3m53s
That is less than half the time on an older card? I have also picked up that denoising is a lot slower on the 1080 than the 980Ti.
Both are on 372.70 nvidia driver, both on windows 10.
