Just to drop a number: With current C31 code Vega 64 does 1.1 g/s at 180 W (settings: 1380 / 1000 @ 0.912V) making it the 2nd most profitable algorithm after CNR for V64 (!!!).
You are totally wrong with your calculation. Vega64 can easily make 50+mhs eth with lower than 180w power consumption. ))
Well ... hmm .. then WTM is off ^^
But even then it does not look too bad - I have to admit with 50 at 170 Ethash wins, next then is SUMO (CNR) and then next is Grin-31 ... so ok right, Ethash is in front but not that much - at least its good enough it should not be such a niche
