well, seems I missed it ... I'm still with old good alexis 20mhs per gtx1080ti
On the 1080ti, I get 20MHASH with 80% tdp and the blake2s sp-mod #2 does 7000MhASH
Thats 350 times the speed of x17.
live prices from zpool
1GHASH x17 0.074btc / Ghash
1GHASH blake2s0.00019677btc GHASH (around $23 a card per day with the sp-mod )
(So x17 has 376 times the payout of blake2s. So it's almost the same payout for the 2 algos.)
You've also got to take into account the difficulty and nethash...
