Thanks for reporting your V8 speeds. Putting these numbers into WTM results in basically identical profitability as ETH mining. However I am assuming XMR V8 will consume much less power than ETH. Each week the speeds decline, currently under stock clocks I only get 23.2Mhs on DAG 221.
Really surprised we can't achieve 1000Hs with these powerful GPUs.
......
They should definitely be able to perform better but unfortunately no one seems to be optimizing for our hardware, at least not publicly.
In my experience yes cn based coins don't use as much power as eth. My non-reference card gets about 21 mh/s on eth so the reference probably get about 23 as well.
For cn based coins use these calculators
www.cryptunit.com and
https://cryptoisme.com/ They will give you prices for the other cn coins based on v8 speeds (or maybe v7?)
If you want to go further you can use srbminer and set it up with moneroocean to mine the most profitable cn coin and get paid in xmr.
Or go 1 more step and set up RainbowMiner, not a tough learning curve, and hope we get lucky with one of our cards doing well on one of the lesser known algos.
Here are some speeds on those algos from WildRig Multi
hmq1725 : 2.9 mh/s
x22i : 2.7 mh/s
x16r : 5 mh/s estimated, due to the random order
For 'exotic' algos, you can use this calculator,
https://crypt0.zone/calculator but still need to know the speeds. RainbowMiner will auto benchmark these but with non-optimized settings.
