In terms of S7 noise, consider the following:

It's roughly the same size and shape of the S5, with what appear to be metal sides. There are three hashing board squeezed in there, and the total power consumption is about 1200W (i.e. twice what the S5 had). Unless you think there is some magic from Bitmain, or somebody else, you should expect it to always be loud unless you are willing to forgo some hashrate and lower the power. I don't think you should hope for some "quieter fan" solution to magically appear.

It looks to me like it's most decidedly "NOT a home miner" if that is underlying your question.

only if we make watercooled verision we could run it in / near are homes

if there is no posebility to make s7 watercooled.
I will be selling / trading fore eqal value is s5'5
cause i cant have a vacuum cleaner on stearoids running 24/7 in my appartmenet.

Nothing official, but bitmain said it's very loud. My guess is that they are somewhere between 75-80 dB minimum.

Thanks, just weighing up options ... the SP20s I have are so configurable in terms of energy use and sound, but the S7 sure beats the power usage per GH ratio hands down. Might wait until S7s are out in the wild and people report back.

Is there any any news on the DB rating of the S7? ... just wondering how loud it might be ... sorry if I missed that Bitmain gave an idea on this.

The current expectation is based on the fact that it appears to have TWO S5 class fans.

If you care about how loud it is, it's probably too loud.

One positive thought (I hope) about the BTC halving:

There will likely be 5 or 6 other sha256 coins we can mine that will give us more income than BTC.

If the LTC halving is any indication - not really. Altcoins are so tiny and most have quick difficulty adjustments so any significant hashrate movement will just raise the difficulty and remove the incentive. Or the increased dumpage will reduce the exchange rate, same net effect.

will someone make waterblocks for s7 boards?
as it will be really hard tot make the c1 and syscooling blocks work I think.
unfortunately i just order myself an s7 and I am not lokking for a vacuum cleaner running full time in my appartment.

bitcoin miners: Moore's law on steroids

S1 came out in Nov (or Dec?) of 2013 and cost ~$4000 for ~200GH.
S7 will come out ~two years later: cost ~$1900 for ~5000GH

You'll get 25 times more calculations for half the price (in $$).

425 with very few amount of HWE. Just if you use good powerfull server PSU.

Anyone else notice this for S7 specs from the interview?

Quote

The S7 brings mining to a new level with Power consumption to Hash rate ratio. The density of the S7 at Chip count per device: 162x Hashrate: 5,200 GH/s (5.2 TH/s) Power consumption at wall: 1300W @ 90% PSU efficiency Power

Typo or updated figure I wonder? It would maintain the same 0.25 J/Gh as the released specs, maybe that is over-clocked?

Probably correct performance when overclocked.
Bitmain state 4,86 TH/s +/- 5%. Which would put normal operating range at 4.61-5.1 TH/s, at 1210W.

I can easily see this thing doing 5,2TH/s at 1300W.

Objections?

based on the s-5 being able to do 400 or 406 freq vs 350 stock ..

I can see the s-7 doing 5300th if you can keep it cold. Big if since it is very small in size.

I could see this being possible in the coldest of places, maybe one of the Scientist whom go to Antarctica for a long time will take it with him and overclock it up.

I'll try overclocking one of mine. Will be cooled by direct outside air with temp at 0 to -16C during winter time. I'm excited!

me too...-5 to -30C during winter time here.
+30 to 40C with the humidex in the summer tho. I had to pull back my S5s to just above default frequency this summer in order to keep them below 60. They survived and i have pushed them up a wee bit recently to get 1.19 THS. So I'm hoping to be able to keep my S7 above default freq next summer. I'm guessing i may not be able to do so.

EDIT: I should mention I put them right beside my AC in the summer so that it's blowing cold air directly on them.

Bitfury makes their miners for data centers. Almost no one in US can use those miners because of the power draw, just like the S5+. That is why I like Bitmain so much, they create miners that the home user can actually run. To bad Bitfury does not make two different models, one for home users and one for data centers. Competition makes companies improve faster and reduces prices for public

You can buy into their data center if you can afford to buy 1 PH. I'm guessing it would cost you $500,000 for 1 PH for 1 yr ?. Then you 're likely stuck with not be able to switch pools...albeit their pool has been rocking lately. My gut tells me that, given their amazing jump in finding blocks, has been due to their new chip .So, I think they have been running their new rigs for at least a month...but what do i know.

EDIT: I think we will see a lot of older miners continuing to come offline soon. So I don't think diff will increase massively as more new efficient miners come online....maybe 3% a month?? But again, what do i know.

Gotta say as a newcomer to this trying to draw information from the Net Bitmain seems fairly straightforward to follow. Real announcements of real chips, closely followed by real products, backed up with data sheets.

BitFury on the other hand is tricky... On their website all you just see in products is the 55nm BF864C55 with up to 0.5J/GH. Then the product BF4500 with 0.62J/GH at the wall. OK so far.

Then in the press from the end of Feb 2015 we are told that they have "Completed manufacturing of it's anticipated 28nm chip" 0.2J/GH and then in the same article.

"BitFury continuously improves its market-leading technology and we are already hard at work on the next generation 16nm chip that is expected to achieve 0.06 J/Gh this year." However I can find no mention of a product based on the 28nm chip?

Now we are told that the 16nm chip "first revealed to be in production in February" has taped out? All very confusing...

So have Coindesk mixed up the 28nm & 16nm information, or are Bitfury, who I have no doubt working on all of the above, just issuing pre-emptive spoiler releases in reaction to Bitmain's actual products?

Rich

If I'm not mistaken Bitfury only sells to bulk buyers/mining companies. Bitmain is only ASIC provider to sell to the open public (atleast as I know of).
Edit: The 55nm products are from back in the day when they sold to the public.
