Apparently MiningSweden has bought S9s
the launch should be just around the corner

proof ?

Only proof right now is on the Mining Sweden website.

They did S7 hashpower preorders a month or two before the S7 got released. So if you go by that, then it could mean the Antminer S9 could be on sale within a month or two.

Difference is this time Bitmain are keeping quiet on it so whether Mining Sweden have just left the cat out the bag bigtime, who knows for sure.

I never heard that antminer release a s8 and i think it needs more power consumption. and i think its not recommend for now.. Because its not profitable unless the s8 is cheap and the your power is free..
S9 impossible never heard it..

There are rumors that some Sweden got S9. I was not told exact name of pool - but Sweden was pronounced

Maybe that is just a campaign to drop S7 price down

Not rumours.

Mining Sweden are selling S9 hashpower preorders on their website. Make of that what you will.

I looked in my crystal ball and saw the Antminer S9 on sale before July

Wouldn't be an S8 - and I doubt there ever will be an S8 for the same reasons there never was an S6.

I could see a faint possibility of an S7- :

More chips per board, running the BM1385 at it's most efficient point.
Probably 2/3ds as many strings as an S7 due to needing more chips for the efficient string operating point.

Very long shot, 2 boards instead of 3 - but that might be an "S7- Lite" instead, which would be a LONG OVERDUE actual home miner but the price point would have to be too low to make it viable to Bitmain as a product given how cheap they've had to drop the S7 to.

S9 would be the "next gen" Bitmain chip - and it better show up a lot sooner than a year from now or Bitfury among a couple others aren't going to leave them any market TO share, unless that "next gen" Bitmain chip and mners based on it are noticeably more efficient than anything then on the market.

Clock rate has almost ZERO effect on efficiency, efficiency is almost ALL about the voltage you run the chip at - thus the need for "more chips per string" to maximise the efficiency of the BM1385 in a potential future miner.

The only option to make an S8 miner is to make a more efficient miner with the same BM1385 28nm chip. Now i can see the logic to create something like S8 (only speculating). After the halving, it is very possible to be hard to find a profitable miner, and Bitmain could decide to create a new miner running with a low frequency; perphaps 250Mhs or 350Mhs and a longer string. They could reach to something like 0.15 or 0.20 w/gh (maybe 0.18 w/gh)? a miner with 350 chips, doing 6 Th/s and draining 1100w?

But if they wanted to do that all they need to do is to turn down the voltage & frequency on a 135 chip S7. It just needs a change to a Byte in the code running on the PIC that controls the voltage.

So it could be done easilly?

I think so, what I do not know is where you can get to with the Hash Rate & Efficiency?

This thread details a repair / mod to the S7 Hash Board that freplaces the PIC with a potentiometer that enables you to adjust the core voltage which gives the same result as changing the code in the PIC

My S5+ was one of my favorite miners, had a good amount of power and was reliable. I had it run a month or more on multiple occasions.

I'd be impressed if I hadn't had 4 of my 5 A2 units run for 4 months straight - befrore I reset my home to "summer mode" and had to shut those 4 down to move them.
The 5'th one is at 4.5 months and still going....

The S3 is my favorite miner. Very silent and strong.
I am surprised there are no S8 already. I was expecting to buy one last march but bitmain lab is silent. Probably they are testing them again for a few months and then sell it.

The Avalon 4.1 beat the S3 on noise by FAR. If your looking for quiet of that generation I would go with it, no other modern miner has come close straight from factory. Others you would have to mod and still not sure you would get same level.

But here is my old review with video - https://bitcointalksearch.org/topic/review-avalon-41-miner-summer-mining-notlist3d-1008726 . I was asked many times if I did something to make it quiet for video

and I did not I did have to get that close for mic to pick it up even.

And they would have kept going but in a few cases I reset them due to hardware errors showing up wrong. Run any bitmain miner for around a month and you will see a negative number on hardware errors.... which is impossible. I normally reset so I could see real errors.

Dragon A2's were beasts I'm not knocking them I know some data centers they were put on a ton of stress... and lived. They were really good miners, only thing they lacked was a nice PSU. Assuming LKETC a2 eventually a PSU dying was kinda common.

*just focusing on this part

I am uncertain if we will see an S7+, it's an awful lot of power needed and I am not sure how well the S5+ was received?

It was a tough sale on S5+ I think. They had much more leaks of info back then and it was known they were using it internally (and might have been selling in China but not abroad cannot remember 100 percent). But there was enough push they did sell it to all eventually.

It was a great miner but expensive, and also a lot assumed S7 would be soon after... so again hard sale. Power was not a big issue due to a decent amount of "hobby" miners grew to 240 and decent amount of amps. It was definitely to big for home miner with 120 volt.

So S7+ would be good miner..... but likely high and a lot would wait for S9 seeing it as way to dump remaining chips if they do pump out S7+'s. (And could be true or not kinda a gamble just like S5+ was on that). So unlikely we will see one. But yes S5+ was a good and reliable miner for those who bought it. Also held value decent as less competition when selling vs regular S5.

Upgrade Boards are a nice idea for the end user, but a pain for a manufacturer, and typically have a higher support cost because of people opening up units and plugging cables etc. Margins are always better on a complete unit.

I am uncertain if we will see an S7+, it's an awful lot of power needed and I am not sure how well the S5+ was received? However as we know the controller board will support it and if it does surface it will be a sure sign that the S9 is immanent.

A lot will depend on how the BM1386 chip development is going? The move to 14/16nm does not seem that smooth, not helped by the Taiwan earthquake affecting TSMC and in particular the newest technologies.

They've never gotten around to offering "upgrade boards" before, despite talking about doing so.
I don't see any major probability of them doing so now.

What I CAN see happening is them offering a single batch of "S7+" about a month before they introduce their next-gen (probably called S9) miner - like they did with the S5+ shortly before they introduced the S7.

But of course, they may decide that was a one-shot option and won't work THIS time with the halfing so close, even if they cram as many BM1385s on the board as they can to maximise the efficiency....

My S5+ was one of my favorite miners, had a good amount of power and was reliable. I had it run a month or more on multiple occasions. I would be interested to hear a S7+ depending on price. If they do it I predict same as other they use about at end to get rid of extra chips/hashing boards.

It would not surprise me if they skip S7+ though. I think they have the design ready for S9's already. I predict they go one fan 3 hashing board, likely were testing the design now for it.
