Bitmain S2 vs Spondoolies SP10

Hello comrades...

It seems that there is a hot topic that needs its own thread as the comparison and smearing conversations are hijacking threads.

Let's keep it clean and have a nice discussion regarding Advantages and Disadvantages of both products.... GO GO GO

No thanks

SP10 is cheaper per Terra.

But still you need to pay more since it is 1.5T.

for those interested sp10 group order is on bitcointalk 3,200.00 usd with shipping 1.5th

will ship starting MAY 16TH In stock

I've no dog in this fight just passing it along

(still imho you get the same coin you make buying at 440 likely)

There is a loss of 7-8 days due to different shipping times.

I wouldn't choose S2 because of that, though.

Get either of them if you are not prepared to buy btc direct dont at all cost spend btc to get btc for either of them. You will not see the same btc back i swear on my mother.

 If you dont have btc not sure of its prospect wanna try mining have usd to spare (as in spare change not part or life saving) then they"llmake sense.

Get them if you want to mine and you want to own a piece of mining history as a novelty. Never as a btc investment to earn more btc.

If you can get it at the same price at the same time then get spoondolies.

Bitmain has edge in availability, spoondolies in general seem to be better build and i've a feeling more reliable to run longer with better electricity consumption.

You mean a one week difference is a reason to choose an S2 instead of the SP10?

[nikolaz]

How we just the hardware on their merits, rather than who ships first?

I think everyone agrees that SP10 is a superior machine, but they did start selling at a very premium price which was a big disadvantage.

Bitmain on the other hand had a great little product called S1, it was great way to introduce amateur miners like me into BTC mining. S2, sounded like a great idea initially until I have seen all of the images of the damaged boards however saying that my S2s did arrive in one piece and did hash (after checking the each board was connected).

In my opinion both products will appeal to different people, all I am saying is that do not be a fan boy and have a blind faith to a manufacturer who is reaping most of the benefits, while you get a machine that might turn profit for you.

I think I might need to offer a 0.1 BTC bounty (I am poor at the moment) whom ever can write can the best comparison for both products.

We based it on who shipped first because that 0.00x daily difference will matter later if btc goes to 40.000$ like the winklevosses said.

ROI for both are shit based on current situation.

If you have a crystal ball and it says 5%diff increment for the entire year then spoondolies will be a winner. Something they seem to eagerly imply with the chart they posted.

[Bicknellski]

Bought an S2. Bought some SP30s. Might buy some SP10s. Depends on how silly I feel. Twinklevoss? Man... let us just say that this year we all hope and expect over 1500$ right?

The SP10 looks like a better product (compact, high-end, well-designed, efficient), but the price is too high to make anything more than a slight profit at current BTC prices. The 1.25U size makes this a clear choice for datacenters where space is limited and costly.

The S2 ships a week earlier and presumably will undergo a significant pricecut once bitmain ships out all of the May 8th batch. (probably to $2100 or so before coupon). The unit I have arrived in one peice and works great. Its not overly loud (big 140mm fans make a whoosh rather than a screeching whizz like the little 60mm stuff in the SP10) and the 4U size is managable for home mining or bitcoin mining facilities that have plently of room.

IMO the S1 is still the champion. It can be hardware-modded down to efficiency levels similar to the S2 and still be cheaper (albeit bigger).


If bitcoin prices go up (as most of us expect if we are buying hardware that looks barely-profitable at current prices) then the S1 will still be the clear winner. We would swing back to the side of mining where the hashrate is more important than low energy usage.

it costs 0.5BTC.  It will mine about 1BTC.  It will use about $250 worth of electricity in that timeframe.
at current $500 prices that is (1BTC - 0.5BTC)*$450 - $200  = ~$50 profit which is pretty minimal
but if we try at $1000/BTC:    (1BTC - 0.5BTC)*$1000 - $200  = ~$300 profit which is significant, basically a 60% ROI


better yet - what we need is the antminer S1.5:
1.45TH / 2.6kW
3U size for rackmount (approx size of a 3wide x 2deep antminer rack)
no PSU(s) included
16 Antminer S1 blades, with slightly shorter heatsinks and undervolted from 1.1V to 1.0V so that the max speed is about 180Gh overclocked but the efficiency is improved
singular controller
~3.75BTC

Do tell me your assumption of diff increase and electricity costs. And why on your diff adjustment ?

Hands down the s-1 still has the advantage for USA buyers.

First consider tax law.    spending .5 btc you need only say you spent the dollar amount that is.. today  it is 223 usd.

Both the sp10 and s2 are more then 600 usd.  so a longer paper trail is required by the usa gov.

Second you can get good psu's like this one

195 usd  runs 3 s-1's over clocked to  200gh…….  so you have 600gh with power for about  850 usd  . 

you can under clock it and get a fourth one to run on the same psu.

The sp10 and all 1th units don't have a lot of flexibility .

  They don't have a big power edge.    think of the older AM blades  they burned tons of watts 110-150 for 11gh  10 to 13 watts a gh.

An s-1 standard clock burns 2.  under clock + pencil mod under volt it burns less then 1.4 watts .. a gh

The s-2 and sp10 do not jump from  1.4 to .3 watts


11 watts / 2 = 5.5x improvement   AM blade to s-1

2 watts / .7 = 2.867 improvement   S-1 to sp10    with the settings of full volts to the s-1 and low volts to the sp10

1.25 /.7    = 1.785x improvement  s-1 to sp10    with both set at lowest volts.


 Also  you can turn a s-1 off and so what it was not much money.

You will not want to do that with an sp10

SP10 is not 0.7W/GH

Such a mess on your post. First of all it's S2 vs SP10. S1 can be ignored.

You praise the S1 for being able to go from 2W to 1.4W with underclock and then you compare the improvement of S1 with the improvement of SP10 when downclocking. Who in the hell compares that on 2 miners? You are truly unique.

Liking the S1 for the fact that it didn't cost much so you can easily throw it at garbage tells a lot of your way of thinking.

SP10 is not 0.7W/GH

So, what it is then?

Its .7w/gh at lowest speed (1th) at 1.45TH my 2 are each pulling ~1325-1350w.

Bitmain S2 vs Spondoolies SP10 = In Stock vs PreOrder

[tzortz]

But S2 was preorder until yesterday.

[Bicknellski]

S2 is in transit... woot. I do like the Bitmain ship as promise philosophy as much as Spondoolies Tech's. It is nice dealing with companies that actually deliver on time.
