For what it is worth,
I see 91.25MH/sec on ETH on "real" Volta V100 with 16GB HBM2...
The card is mind bendingly fast, generationally better than anything currently available, but at the price, it is certainly restricted to the very highest end of the market. I don't believe it'd make sense as a popular mining card, given current street price of V100.
Still, an amazing device.
