Topic: Should Bitmain make a Q7? (Read 4179 times)

Both S5+ & S7 have two fans, difference is in the board length as the S7 has an extra column of Chips to accomaodate.

 2 fans on an S7 vs 1 on the S5+ is likely the difference there.

I think it will be a upgrade kit.  The controller is set up for 3 units already it looks like.  So would be easy to throw a pack of two miners without controllers and call it a + upgrade or something like that.

I think they will do it down the road though, not at launch.

I think they will sell additions, not exactly an upgrade kit. Basically you would just need to plug a S7+ on a S7's controller board. At the very least, it look like everything is set it place for that.

Just a matter of time before there is an S7+ I'm sure - they already have the infrastructure in place.
 I wonder if they'll offer "S7 -> S7+" upgrade "kits"?

The length of S7 is 301 mm

The length of S5+ is only 275 mm

The lenght of S5+ blade is 180 mm , height 127 mm at lower edge

The length and height of S7 blade are not known.

yeah, these would be versatile..and a much better seller to retail crowd/us.
bitcoin market is truly messed up right now with basically no large scale suppliers except BM.

It was truly a tank.  It seemed like the S3 could take it all back then.  The only problem I ever had was once network went down during flashing.... but was not expensive to fix.

I don't see them doing this though.  I think the new bitmain products are going to be big.   Easy to put in a data center if they want.

bring back the s-3 with s-5 chips

2 boards 2000 gh  500 watts

the s-3 is the greatest miner ever made if used for heating as its primary purpose.

imho quite miners are very important to keep bitcoin decentralized.
as stated in the op: they can be used as heating devices which essentially means: mining is only a by-product. no data-center can beat this.

i really hope many vendors will enter this consumer market.

The sad thing is likely they have R/D working on lower NM chips.  So they will be ready once they decide to release one I have a feeling.

But with being only one right now they can keep 28 nm and make bigger profits.  It was a business decision to keep 28 nm.  I have a feeling they can win at both front's with all the resources they have.

And by the time they switch to 16NM in 2016, the process cost will be much lower and they will be able to jack the price up while still keeping the cost down. Monopoly hurts.

Also remember they kept the 28nm chip.  They have mastered making it at this point.  Others went down in NM.  Bitmain is at a huge advantage keeping same NM.  They no doubt have much cheaper costs sticking with it.

They could have made a hefty profit at I suspect much less.  But greed came into play... they jacked price knowing only one putting one out right now.  I suspect it will go down one day but not till there is someone else producing miners to public.

I am close to 100% sure that they can charge $1000 for S7 and still make a hefty profit.
After all, there are only 2.7 times more chips in there. $350X2.7=$945
the rest is cable and plastic plus $15 for a extra fan=less than $1000 with similar profit margin as S5.

I was surprised with price.  I bought a S5+ just as I was bored and wanted a new miner.   I am happy with it but I do think I overpaid most likely.

On S7 1800 dollars.... looking back I think I got my S4's new for around 1200 dollars.  Dont remember batch.  But seems miners are going up in price.  Unless someone else puts out a miner we are likely to keep seeing high prices. 

And to the topic I don't see them making a Q7.  Noise is not something they worry about I don't think.  It's become a mod if you want quiet.

Besides the power/noise profile of the S7, the price is a real deal breaker for me. Unless and until Bitmain has a reason to reduce the prices (e.g. serious competition), they will get a premium price for the S7. I think any BTC price machination are strictly cover for having Bitmain adjust the price the way they want. We saw this during the early days of the S5, and never made sense to me, It always seemed more related to what Spondoolies was charging.

A quiet S7 would be a great thing.

the problem is now that there is no competition, the S7 is sold at a price of $1823 USD or 7.5 BTC, the real price if BTC goes up is in BTC, and if BTC goes down it is in dollars.

If BTC goes over $300 dollars, the $1823 will go up, most likely over $2000, and if BTC goes down then the $1823 stays, unless if it goes down a lot, the miner price will not proportionally goes down.

The pricing scheme seems to be calculated at an amount you will never ROI.

https://bitcoinwisdom.com/bitcoin/calculator
This calculator takes into consideration difficulty increases.

at a 10% difficulty increase ( 20% is the default) and free electricity you will not ROI in over 530 days, and will end up 1.7 BTC short or ROI.

at a 5% difficulty increase and free electricity, it takes 296 days to break even.

Let compute the fair price of an S7, using difficulty increase of 10%, and 15cents per kilowatt, and a ROI of 3 months:

you will make 1.2 BTC, loss of 6.3 BTC.

lets use difficulty of 5%, and 10cents the killowat, for 6 monts:
3.5 BTC made, 7.5 expended, loss of 4 BTC.

Using this calculations it can be seen that the S7 will never ROI, and it is extremely overpriced, more than double what it should cost.

from a hardware point of view it is nice, but it does not help if it will never ROI, I would personally buy a few if it was priced at a price in which I could ROI, or even break even in 6 month, but the fact is that I will not even break even at 2 years.

Do not believe me? use the calculator yourself and plug in the numbers, even with free electricity you will not ROI.

Most likely price will go down, since few are buying, the item has not sold out in many days, but Bitmain has to seriously stop being greedy and lower the price by at least 60% if we are expected to have the opportunity of at least reaching ROI.

I am hoping that BTC doubles in price, but that will not help, since if BTC doubles in price, Bitmain will double the price of the miner.

The real price drop will be soon, and that is when the block halves, there will be a huge market of used bitcoin mining equipment, that will make all prices new or used hardware  to drop, I am personally waiting for that day, or the day in which I can get hardware that will ROI in about 4 to 6 months at most.

But the AntRouter isint really a worthy miner. Its like a single chip running on 1-2W. Maybe it would run as a plug and play node, which in itself could be of a certain use but that seem pretty much like it. 8-15ghs isint worth fawning over.

A quiet S5/S7 on the other, now that sound nice.

Sure, yeah! We really need miners that can be a lot more silent so that we can use them to heat our rooms this winter!
that would be really great!
