If you are a trucking company would you buy the truck that costs more and need more fuel but drive on the road all the time, making money. And if something is defective you have very good customer service.
Or the one that is cheaper, needs less fuel but you have troubles all the time, you have to argue with the customer service about very cheap spare parts even if you bought hunderts of trucks from them....
...
As for your analogy....
That's so flawed that I don't even know where to begin....
Since 66 is the LCM...
| | Unit Cost | Power Usage | TH/s | Power/TH | (kWh) cost USD | Yearly Power Cost/TH | Yearly Power Cost @ 66TH | Purchase Cost for 66TH |
| A7 | $1,222.29* | 1,000.00 | 6 | 166.67 | $0.10 | $146.39 | $9,661.87 | $13,445.19 |
| S9 | $1,232.00 | 1,185.80 | 11 | 107.80 | $0.10 | $94.67 | $6,248.40 | $7,392.00 |
Edit: purchase price alone, you could buy 11 S9s (not counting the 1 that the power cost difference makes), throw 5 in the trash (having
never used them) and
still save $.
