Subject: unexpected benchmarks nvidia 1070 ti and 780 ti
I've noticed inconsistencies after adding a better card to a system. Originally I noticed this on the latest kali linux with 1.80 jumbo. I've since spun up an Ubuntu 19.10 instance with the latest bleeding-jumbo release. Have tried this using nvidia drivers via apt repositories and also installing the latest from nvidia website. Anyone else experience slower than expected benchmarks? I'm not a hashcat user but ran a test to see if differences reported in output
