Someone measured Z9 at about 380w at 15k, I did not, but mine runs at 54C, fan at 65%. So minimal heat or noise. And at current profit level power is pretty immaterial. It will become an issue much later in life, by then most coins may have already forked.
Edit: And there will be only a week's head start at max, I think, as Bitmain should be shipping rest very soon.
I have a hard time believing that a 50+% stable overclock results in only 380w @ the wall. That can't be good for the failure rate. You can't overlock inno miners, but they do release firmware updates. The A9 website says ±6%. The Z9 minis variance was ±5 when announced. What's to say that the A9 doesn't have a lot more to give if Inno allows it?
The absolute soonest bitmain could start shipping these miners is on the 18th. The first few days of shipments would likely be the day 1-3 customers anyways. Realistically people who didn't order in the first few days won't see their miners for 2 weeks at the
earliest. 3 weeks is a lot more likely. Their official shipping schedule is from june 20-30th. I'm guessing 1000 units a day which would confirm the rumors of a 10k units in batch 1.
I just checked, someone in Z9 thread measured it at 385w at 15k. And I have zero HW errors at 15-16k.
Now Bitmain's is promising a big update by 15th on Z9. My guess is that will ship everything in batch 1 by 20th, max. I think there is a reason why they pushed out few Z9s very early in late May, they were trying to get ahead of Inno A9 (publicly unknown at that point). And in the same light, my guess is everything gets out by 20th.
Leaving this aside, anyone with 5 batch 1 Z9s will hash at 75k at the same price point as A9, that's 50% more. Even a week or two advantage is not enough. I do agree that this argument is a bit mute as while ordering Z9 no one knew about A9, so its all hindsight in a way. But the this does not discount Inno's high pricing on A9 and tactics which they employed on D9s, pretty much a disaster for owners.
Edit: And don't discount a bigger Z9, not mini, being announced soon, hashing at 60k at $4000. Inno has only a month max to sell as many A9s it want at current price. Next revision will be to $3500 as soon as a bigger Z9 is announced.
We would really appreciate some feedback.
