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 $.
your price is off on the a7 they are $888.00 before shipping not 1,222.29
I paid 2,032 for 2 with 1 controller so if you use 1016 not 1222.29 you total for 11 = 11176 that counts shipping and gives you 5 rasp pi's
my last s9 was 60 to ship so 1232 + 60 = 1292 x 6 = 7752
so s9 = 7752
avalon 7 = 11,176
if 1 s9 breaks that is 16.667% loss
if 0 A7 breaks that is 0% loss
so 7752 x 1.16667 = 9044 act cost of the s9 not 7752
so compare 9044 to 11,176
next if the old s9 is really 83% block luck
9044 x 1.16667 = 10551 is what 66th of old s9 costs you vs 11,176
power you did at 10 cents do it at 5 cents
a7 = 4831 not 9661
s9 = 3124 not 6248
So this would be a lot closer to realty for people that can do 66th of gear and purchased the old s9's
cost of the old s9's were a lot higher then the numbers used here. but some of the time blocks were 25 not 12.5
But that just numbers.
So if you want to prove a point at least use the right prices for the avalon 7's
it still shows that s9's are better not a lot but still better
