...
isn't 5THs about half what an A7 should do?
You been smoking something?
Kano.A7 5.096k 1s 8,397 35,604,892 7.58THs 26s 0.532% 0.004% 5.24THs
also - Pool has is currently displayed as 32THs not 32 PHs
CKPool: 32,745.50THs
Shares: 941,824,361,119 (334.22%)
Invalids: 1.1M (0.62%) · 3.6G (0.38%)
That says 32PH ...
And that page also says 7.58THs ... yeah funny about the inaccuracy of hash rates
Also as I said above ... it takes a while to ramp up ...
Also looking at one number when there's a graph of quite a few that says otherwise ...
Interesting - I was thinking that this A7 miner was meant to be serious competition for S9
Kano - thanks for jogging me to check my facts in detail.
so I checked some details
A7 - 6.0THs
S9 - (B23) 14THs
Power
A7 - 1000W (but Canaan advertises 900W)
S9 - 1500W (with +10% added)
Cost
A7 - $888 (Looks like a lucky number to me? Why not when your competition is out of stock.)
S9 - $1,700
W/GH
A7 - 0.167
A9 - 0.107
So it looks like an s9 is significantly more efficient (maybe 30-40% better - thats a lot).
Sure A7 is better than an S7 (0.25W/GH) but quite a way off an S9.
$/GH
A7 - 0.148
A9 - 0.121
So S9 is marginally cheaper to buy per GH
Based on the efficiency alone - I would be swayed to an S9 over an A7. The efficiency difference is huge IMO. Let me know if I got something wrong please.
Of course they are out of stock - so its not an option for now.
And - not to miss the claims of quality reliability, flexibility and life expectancy of Canaan machines. So this must be factored positively.
Also - claims of shenanigans by Bitmain with software - should be factored I guess
Life expectancy has always factored low for me since miners become uneconomic quickly any how - but they must last 12 months at least.
Some say that life expectancy may be more important in the future as we won't see such rapid efficiency gains in the future - lets see.
I expect Canaan to tweak a lot more from new batches if they want to really be competitive.
I've seen a lot here complaining about Antminers.
I must say that maybe I have been lucky with all my machines from S3's to S7's - no S9's (still waiting for resolution of a clear winner here for my next upgrade - and a price drop hopefully).
I have always run all my Ants overclocked to max (as each machine can handle differently) and never had an issue as long as quality and ample power supply PSU's were used.
Also - they are regularly serviced and cleaned out - like every 2 months or so.
Always managed to sell them in perfect working order for a good price.
Had an S7 fall from the top rack in an earthquake the other day - still running perfectly fine on the floor with PSU dangling above in mid air.
So - I'm still leaning to Ants - but watching all.
Also - just reporting the error on the top of every Kano.is page
CKPool:
34,724.84THs (This should be PHs)
Shares: 117,281,197,547 (41.62%)
Invalids: 137.5k (0.62%) · 362.3M (0.31%)
Yes its correct in other places - but since every page has this error its just something I thought you might want to know about and might be worthwhile fixing.
Cheers - usukan
Thats 32 724.84 TH which is correct. Remember 1000Th is 1PH. Kano has just chosen to display the pools combined hash rate as terra hashes which is completely fine.
If it were to be displayed in PH it would be 34.724PH. Note the comma joining the 34 and 724 making it 34 724TH
