Some months ago with Ubuntu 18.04 a GTX 1030 was slower(!) with opencl,
but now the 1030 is faster, about 2x without opencl, while the 1660 is
about 10 times faster with opencl. Of courese this depends on the test
scenario. I used the testfile bench.srw from the phoronix test-suite.
In my case it was significantly faster _if_ it worked at all, see table
here:

It also depends a lot which nvidia-driver you use. It worked without
problems, when I installed the nvidia-driver during installation, if I
installed it afterwards I got mixed versions.
proprietary driver packaged either from repository or ppa - tested both.
Updated BIOS
used several distris
no effect
now the GPU is just money thrown out of the window :(
