How much worse in % 1080 is compared to 1080ti? Difference in price is big enough to consider 1080, but let`s say Zcash, what would be the differences in sol/s between them?
Thank you
There is a big difference. Generally 200 sols/s between the two assuming both are overclocked to the same general level.
If you care 1080ti can also mine Eth at 38 Mh/s overclocked while the 1080 (25 Mh/s overclocked) is semi crippled at Eth mining. For reference my 3 GB 1060's running +1000 mem do 25 Mh/s.
Most people dont buy 1080's for mining, especially with 1070 Ti's being a thing now.
