I haven't found any benchmarks for the GTX 1660ti but there's a forum post that says it should be comparable to GTX 1070. When I benchmark WPA, bcrypt and LUKS I get similar results to 1070 benchmarks posted online. When I crack actual hashes WPA results are similar to benchmark but bcrypt and LUKS just crawl along. For example, bcrypt benchmarks at 12000 H/s but my hashes run at 115 H/s.
I'm running latest hashcat from github on Ubuntu 18.04 LTS.
NVIDIA Driver Version: 435.21
Hopefully someone can give me a tip. Thanks!

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.
