For me the most important:
10000 Avalon 2.82THs 780BTC $ 78,000 + or- 25KW
11 Jupiter 4THs 770BTC $ 77,000 + or- 11KW
41% more hashrate
66% less power
No production cost
From 10,000 overclocked Avalon chips you can get 4TH/s, good and stable (non overclocked 2,82TH/s).
And chips are priced in BTC - wait till BTC hits $30 to $50. Then the $/GH/s of Avalon chips will be waaaaay better
Do not forget if you OC any chip. Need more watts per chip. Also more watts for the cooling system.
We must have a 282Mhz chip has a stress if it runs at 400Mhz. Higher possibility of failure. +42% OC is much for air cooling.
Just think that your competitors do the same OC.
Bitfury 120 to 170 12.7 $ / Ghs
BFL 25 to 35 50 to 71 etc. .. 35.2$ / Ghs
KNC 200 to 284 400 to 568 12.3$ / Ghs
Avalon 2820 to 4000 19.5$ / Ghs Not counting the manufacture of miners
35$ / Ghs If we value the manufacture of each avalon 4 modules at $ 2,000. 31*2000 = 62000+78000 = 140000/4000 = 35
I have not added in any device the liquid cooling system and new PSU + Watts needed.
Yes, but I'm assuming that BTC price will go down hard, to at least 50% of its actual price (so around $50), and that Avalon's chips are priced in BTC. From what Yifu said, they will "raise and fall" with BTC and won't change the price regardless of the exchange rate. If you consider a BTC/USD of $50, the $/GHs picture changes a lot.
