While comparing miners here:
Bitmains S3 is basically the competitor to the sp10.
However, I have no doubt that bitmain will come up with a fully rackmountable 4U 1-2kW solution with 0.5W/GH at the wall.
This will in turn be the main competitor to the sp30, and should not require a preorder.
Exciting times, let´s see how it goes.
How so? SP10 are not for sale anymore and are much more expensive/less efficient/less home friendly than an s3. Also don't forget that 0.77w/gh is before underclocking. I wouldn't be surprised if the S3 was already capable of 0.5w/gh at the wall.
9btc buys you 6TH in 2 weeks or ~3 months. It's a pretty simple choice if you ask me.
Where do you get these numbers on which is a better value?
What is your fetish with Antminer and Rockminer? Its like comparing a 10 year old 22" brick of an monitor with a
new LG LED. You could have something that takes up an entire 6 foot shelf or something that fits in a 2U server rack slot.
What does it cost you to run 12 S3 units?
Lets look at that shall we?
You are going to need at least 6 BIG power supplies.
So that 2 S3 units for 1.5BTC is now more like 2 units for closer to
1.8BTC with a good 1000W minimum Corsair power supply.
So, now you are at near 11BTC for all the hardware.
Thats abouot $7000 at current exchange.
SP30 at the group buy was MUCH cheaper. $4500 ring a bell?
NOW, at my current hosting location, I can run my SP30 for $150 a month on 208V power
and around 20 - 22 degree temps. It doesn't matter if it uses 100 or 10,000 KWH.
Lets add up the power usage of the S3.
12 S3 units at 370W each = roughly 4,500 Watts.
Now, Im going to give you a VERY generous power rate at 10C.
I know most people here are paying around 15C.
That is nearly $330 a month in power. Plus the amount of space
and tangled cables you need to run 12 is ridiculous compared to taking up
2U of space at my data center.
AND, I think unless BTC hits a stable $800 and NEVER drops, mining other ALT coins is
going to be much more profitable VERY soon. If megabitpower adds their 50PH of hashing
to the BTC network per month like they want to do, well to hell with BTC mining. Its dead.
Let the fuckers have it.
