Dear all,
we currently are testing our new RTX 2080 cards (MSI Geforce Seahawk RTX 2080). However it seems that they are about 2% slower then our GTX 1080Ti Cards (Similar model).
However from the benchmarks on the AMBER webpage I find that the RTX 2080 should be about 10 - 20 % faster then GTX 1080Ti. Is this correct? If so any ideas why this is not the case for us? Is there some “trick” to use during compilation or so? Or are they done with some patches of AMBER which are not yet public?

Thanks a lot in advance

Alain Chaumont

P.S. We are currently using CUDA 9.0 . The size of the systems is about 130 000 atoms.
