[ANN] Sfards:SF100, the first 28nm Dual-Mode Miner is accepting pre-order now

[Guy Corem]

If the j/gh ratio is real, this is gonna be a game changer! 

it wont be. guarenteed thats at the lowest voltage/frequency, and probably for just the chip (doesnt include regulator loss, PSU loss, other power draws like a controller/fan)

realisticlaly in a final product, this would probably range 0.28W-0.50W depending on settings (ie: similar to the Bitmain chip)

Agreed, looks extremely similar power consumption to the S5's chip on sha256 mode. The scrypt mode looks more appealing, and we don't yet know what we'll be able to do in dual mining modes. If its anything like the gen 1 chips then I don't think many people will dual mine.

Dogie, I think it's high time you'll put a disclaimer about your BitmainTech affiliation somewhere in your signature or personal text.

Sounds great but at what cost $ per gh would you be willing to spend on this?  That will come later of course but an estimated goal would be nice to know.

yeah thats where the rubber meats the road.

+1  Power consumption actually appears to be about 20% lower on-chip that the BM1384.

Yeah there should be a small note that's he is affiliated it does seem to be skewing his post.

That said, 15-20% lower on chip level isn't really a 'revolution in mining' and certainly won't make people all of a sudden invest in mass quantities of hardware (especially larger operations with minimal power costs where the acquisition cost of hardware is the bulk of the capital outlay).

Another post that says nothing. Lowest efficiency 0.19J/GH, but at what hashrate? My guess 50GH. Highest hashrate 152GH, but at what efficiency? My guess 0.4J/GH. "After strenuous testing" you are just posting marketing shit and no meaningful data.

well if it is able to be stable at .45volts none of the current chips do well at that level.

so here is my prediction they will mope along due to terrible btc price and when we finally see it will be too little too late.  This is and has been true for most asic builders most of the time.

  Always too slow to release it always a bit short.  And if it is really a big improvement the builders all mine the coins like a mofo before anyone gets them.

I agree, then new (all) users will be aware at first glance that his forum waffle / trash talk is sponsered by bitmain.

Otherwise, I look forward to seeing the final results of this chip (even rigs with this chip) ...... rubbing my hands in fact. Well done sfards!

The option is there to switch though which is nice and if they can get lower than the s5 Bitmain will finally have a reason to push out their next series, which I suspect is ready but they're just waiting.

I think they are ready or  were all most done when the S5 came out then they held off and upped the S5 price that one day, I'm willing to bet but Polly wrong but that other DEV was this one that bitmain was basing that S5 price increase on. and they were ready to go to a price warr if these hit .

I only speak on behalf of those companies within their own threads, am I not allowed to hold an opinion any more?

Anyway, the lowest tested efficiency is extremely close to that of the BM1384 and BE300 tests. And as others have already said, the lowest efficiency point is not going to be the shipping stock efficiency. Hence people should remain realistic in their expectations. Do you disagree?

Asicminer's BE300 is what that was based on.

They have been a little slow on updating us.  That is very true.  I would love to see them do well.  The gridseeds were very popular so I hold a little hope that another company releases a good product.

But I guess time will tell.  It's hard to tell much yet just not enough info.

I've run the Gridseed chips in every form factor they were ever built in, and they were solid gear for a long time.  Hopefully this will work out, more competitors in the home/retail space can only be a good thing for us miners.

I had 35-45 of the 5 chip and 17 of the blades.

 I liked the gear.

They stated April for functioning miners right?
Did I misunderstand?

I hope they haven't been mining with full blown hardware in a 250,000 square foot facility for the past two weeks and are telling us they have chips ready for others ala bitstain style

I was discussing this with a good guy the other day. It was obvious to both of us our equipment was mined with for a considerable time. He has new S5s, with new being the chosen word, but not the actual product. I read the BS about the sand coming from an open window or windows in the test area, but I also have seen more than enough pictures and heard from so many others about the dirt inside their equipment. My bud asked me if I wouldn't do the same thing. I said no, I would never be able to sleep at night. I would sell them as used for X amount of days. I believe people would still buy them at the same price. Look at how many people are still buying them. You can be honest, make the same amount of money or more, and feel great about your choices. Besides, I seriously doubt they need to sell the miners with the amounts they have already made from mining.

Sfards, take a lesson from what has been done to this community and don't perform unnecessary testing with the miners. I hope you have a product close to shipping. I want to support another company who has class. I hope the photo on the website is not a start of bad things to come. That single act does not mean as much in my opinion if you mirror the SPtech actions and reputation, but if there are a trail of tears behind it, then it speaks volumes. Only time will tell.

Saying all of that, when do you *think* we will see a functioning product, and will you hold true to the April date or will it be longer?
I think those are fair questions you could answer without giving too much away.

Are you planning batches?
IS there a way to be on some form of list for orders when they begin to ship?
If you have review units available I will purchase one from you, or from one of the reviewers.
I am a sucker for toys, and with the SPtech recommendation for this company I am ready to throw some cash at them.

I think the point is that you represent yourself as a community member much like others, provide guides for numerous manufacturers, implying impartiality, but are also paid by Bitmain, a walking (or typing) set of contradictions...

The BM1384 chip at the lowest voltage uses about .249J/W according to the datasheet. So this chip is about 30% more efficient.

I think a big part of this will be release date.  I really like direction of releasing specs.  But we have not seen a prototype so hard to know a lot yet.

well if sidehack gets the BM1284  to run at .35 watts

It may be possible to get  this chip to run at   .28  would be nice to see a piece of gear in the .25 to .32 watt range.

Waiting for it.
