300 watts / TH per that web site original poster listed - so a little but not a LOT worse than the S7.
I crunched the numbers though, and not looking like this Avalon 6 (IF it actually exists and IF the specs and price are correct, between original poster and that Chinese website) will RoI ever even at 3 cent/KWH electric, unless Bitcoin price sees a substantial jump or diff increases flatline REAL soon.
I'm guessing it will really depend on the price tag on the unit. By the time they release it, since they are taking too long to do so, i don't think they will be able to price it at much more than 1
BTC/TH/s.
Well when i say that, i'm thinking about the cheap thermal dissipation design. Albeit better in the new S7 form factor.
The software being rickety at best and important feature are left out on purpose. For example, they removed Volt control on S4 in later firmware while its possible to hack it back in and it work just fine.
The software is ultimately low end, not very good. Compare it to the SP20.
The noise is bad, compare to Avalon 4.1, although with the fan control and low ambient temp, its not that bad, just not excellent.
The plugs are on top of the miner, so its harder to stack, if all the inputs were behind, they would be more manageable. Again this is worse with the S5 and i'm not sure with the S7, but still. Compare it to the other mentioned miners.
Going into it though you know what your getting. Bitmain has kept pretty much same software for all of miners, they are very similar. So it's not a surprise on software side.
Also you don't want inputs on back as this is where hot exhust is. So putting say power cables in the hot exhust is just not good planning. I agree avalon 4.1 and sp20 did a better job with inputs on front. But the S5 was built to be low priced. It was not encased in a nice case like other two and used plastic sides.
If your wanting change I do not think it will come from bitmain as far as far as software design anytime soon. As far as hardware going from 2 blades to 3 with S5+ and S7 I consider hardware a decent change. Also a metal case compared to plastic sides.... so there is some improvement on hardware side.
The hot hair should come out to the other side, not the side where you plug your things. You could use good solid plastic, it would be lighter than metal and still very solid. Tho not much less expensive. And my biggest grief is with the software-hardware part of the software. The volt control is bad, the fan control is finally here but still very bad. Etc.
