I think with the S5+ monster and the S7 using the same 3 card chassis and controller with provision for 9 Hash boards, combined with the lack of an S6 and we have seen the way forward as being very high density modules, based on a single hash board design for single unit and 3 unit rack type units. Entirely geared towards Farms, with an S7+ and 14.58TH/S is the next logical step.

I also think that the full custom 28nM BM1385 may not be beaten by a semi custom 16nM chip and so the BM1386 will also need to be full custom. They are however now up the learning curve for full custom design and are a good step ahead of the competition, so will probably be in a position to release this at a moment of their choosing.

Bottom line is I think from a Bitmain point of view the days of supporting the Home Miner are over. Our best bet is a sidehack BM1385 design or what I posted in the S7 thread.

If I had the money what I would love to do is buy 2 S7. Take out the middle Hash boards and make a 3rd 2 Board S7. Needs confirmation that the unit will work with an S5 Controller board (The picture actually shows an S5+ controller & we know that an S5 Controller works with an S5+) We then have a 3.24TH/S, 860W S7- for 5.5BTC. A very nice unit, ideally suited to a 1200W PSU and home use.

Beefcake!!!

I think a q model would be popular. The s7 upon first glance seems to be targeted towards larger mining operations. I think if bitmain made a smaller device like the old u3, that is a much smaller form factor with the new chips, I believe this device would be wildly popular. Especially if you did not need a special psu to run it.

But I get the impression that bitmain will have no trouble moving the new s7 units, so I can understand that they would want to focus on the most profitable option available to them.

I don't think they will be making a Q7. I think quiet miners anymore are mods when it comes to bitmain. They just do not make a quiet miner.

I do find it interesting how many PCIe cables on the S7. Seems like a good way to sell their PSU with many of them. Seems like a business decision there.

I want to have BM1384 prototypes of 4-chip pod and 30-chip S1 before the end of September. BM1385 prototypes within two weeks of sample chip delivery. A factory order of chips from Bitmain would probably take two months for delivery. In that time I could get a full stock of PCBs and all components. Once chips arrive production would start immediately. Probably run out the full batch inside two weeks.

Estimated material cost for start-to-finish would be about half a million dollars per batch. That's a butt-ton of money and it all hinges on Bitmain and sample chips. It also hinges on having a working design, which right now is merely "in progress". Let's not get ahead of ourselves.

How many do you want? If we can get money for a full batch of chips, and the batch size is the same as BM1384, that's enough boards to outfit over 1600 S3 right there.

It'd be nice if Bitmain didn't abandon the S1/3 customer base, since they were about the only ones left servicing them and they are definitely able to produce the machines in whatever quantities they want.

FUN > ROI

In lieu of Bitmain doing this themselves, GekkoScience are planning something in the S1/S3 style as long as they can be supplied with chips. See the last few pages (as of this writing) of https://bitcointalksearch.org/topic/gekkoscience-bm1384-project-development-discussion-995675 and/or https://bitcointalksearch.org/topic/request-for-discussion-proposal-for-standard-modular-rack-miner-1158807

Smack on the head there! 2 boards (even with fewer chips) in the same form-factor would be lower priced (though premiumed as per S7) and there would be a fair bit of demand for such, not just in the US, but in most temperate regions (even tropical!) from home miners.
