Topic: Bitmain S2 vs Spondoolies SP10 - page 3. (Read 5432 times)

I like you bro. I also like the sp10  .  let me buy one with a cc  at 1800 to 2000usd and have delivered it to my home in three or four days and I would have one of them mining right now

 The fact remains I can't buy one for 1800 to 2000. with a cc and get it in four days. I have to create more tax work when I file to buy it.
 I also am in the same shape if I buy a S-2.  NO CC or PP

I have two options buy s-1's 1 or 2 at a time. No extra tax work.  Order monday get it friday.

So Monday the 5th I order 2 S-1's 400 gh for 1 btc I get them Fri the 9th .
 I  can make 3 separate orders on monday the 5th each for 2 machine total of 1.2th total of 3 btc or  about 1320 usd


Buy 2 of the evga 1300 watt psus 400 usd .  So for 1732 usd I am hashing on fri the 9th at 1.2 th using 2400 watts


Buy your sp10 on  may 5th for 3200  When do I hash??

Buy the s2 on may 5th for 2200 usd (I have 6 coupons) it hashes on sat the 10th.

So buying your machine I have at least 7 maybe 10 days  longer wait time before I hash.

Buying the S-1 I hash in quicker time and as a garage hasher I have the ability to set up the 6 s-1's.

As A USA buyer no extra tax issues.
I have 6  running as I type.  they pull 1.2th and pull 2400 watts they are earning 33 usd a day and they burn 9 dollars in power. 

So they gain 24 bucks a day.

 your machine would cost me 1500 usd more to have THEN 6 s-1's  with the evga psu's.

 I would need 10 to 12 days to own one.  I love your gear but not the price or the wait.

More like 2.05/Ghs vs 2.13/Ghs

It's a semi pre-order because until now we had pre-orders for non-existing products. SP10 is a very real and good product.


Which is 2.11$/GH compared to 2.13$/GH if you buy a SP10 from my Group Buy.

Brilliant, didn't think of that.

The best strategy is to buy a S1 first, and then you will get a coupon worth 400 USD; then you use this 400 USD coupon to buy S2, so you will spend 2599-400+220=2419 USD to get 1000+180=1180 GH/s

My only worry is summer time... at 30C ambient temperature I believe SP10 will perform better compare to S2 (please correct me if I am wrong please correct me)

Can you imagine if all of these companies delivered on time, we would be having a discussion about SP10 vs S2 vs Neptune vs TerraMiner IV vs CoinCraft Rig etc but sad thing is there are only less than handful companies deliver quality miners on time.
 

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.

But S2 was preorder until yesterday.

Bitmain S2 vs Spondoolies SP10 = In Stock vs PreOrder

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

So, what it is then?

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

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


http://www.rakuten.com/prod/evga-supernova-1300-g2-1300w-power-supply-110-v-ac-220-v-ac-input/249973555.html


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

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

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

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?

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.

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.

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