AMD is only the king of mining on some algorithms, on others NVidia blows them out of the water, and there are a few it can be fairly close now that the RX "good mining" AMD card pricing is finally getting back down to reasonable.
Don't ASSUME that ETH is the only thing out there like way too many clueless website reviews, even if it does have more GPUs mining it than any other algorithm.
Could you please give me a concrete example of one single coin and one single Nvidia card?
I want to make my own calculations and show you that investing the same amount of USD you will have higher returns by using the AMD card rather than the Nvidia
Please do NOT confuse me here, i am not trying to annoy you or anyone else
I am trying to benefit myself and others viewing this thread
I am be missing some info and i am very happy to learn from you
However, if Nvidia is able to blow up AMD on a particular Algo, the question remains how much does that Nvidia card cost, and how much does it net at the end of the day, then you will have the net return per dollar invested
For example if Nvidia nets 3 dollars a day but costs 900$, this means that each dollar invested returns 0.0033
However, if AMD costs only 400$ and returns only 2$ instead of 3$, this means that each dollar invested returns 0.005 which is obviously higher than Nvidia
So please give me a specific card and a specific currency and i would like to make my own calculations and come back to you...
ZEC. Compare against any of the Nvidia cards in the GTX 1070 to GTX 1080 ti range - on both "power efficient" and on "max hashrate".
AMD cards are ALMOST getting competative there again - but even with RX 570 cards in the $209 range they still have a bit to go to manage it.
To be fair, go ahead and include the "return" figures for the AMD card doing ETH vs the NVidia card doing ZEC, as that is probably going to be the "best option" for each card.
Don't forget to factor in SYSTEM COST - the AMD card might be half the price, but you also need to add in the "cost per slot" of the system itself on each side, which will be the same.
It's a more fair comparison to compare a common 6 card RIG of each card involved, since cards don't mine by themselves.
