The one used in most mining farms during 2013 was Bitfury/BioInfoBank 55nm chips they run at 25GH for 25W per blade (16 chips) but can run faster if you put more power to them and add cooling BitBurner Fury got them up to 52GH.
http://www.bitfury.org/ and http://www.bitfurystrikesback.com/ and https://megabigpower.com/ and https://www.asic-hardware.com/
They just sold a $5million contract to some investors. http://www.businesswire.com/news/home/20140123006299/en/CoinSeed-Invests-5-Million-BitFury-Bitcoin-Mining#.UuQrHPvLe00 in 2014
But that was not the first one also see the BioInfoBank 100TH Mining Farm Project https://picostocks.com/businessplan/19.pdf is from 2013.
If you have any sense you will write your dissertation about whether the BioInfoBank 100TH mining project reached it's investment goals as it's set out in a clearly defined business plan that you can critique it with hindsight.
Hashfast and KnC have delivered more efficient 28nm products, but KnC limits production runs, and Hastfast is too new to know reliability (arrived this week).

I know that mining is not profitable at all due to rising difficulty caused by "mining-noobs", losing a lot of their money.
If the block reward exceed the cost in electricity and roi is impossible then will some miners (with lower hashrate = lower probability to find the block) shut down, and then will the difficulty go down, and then will roi be possible for others. The system will self-adjust to a level where there is a profit for the miners.
You won't see this happen in the next few years. Because most miners dont think rational like that. They think like: Bitcoin is going to rise in value, so it makes sense to mine. But they don't see that their revenue would be significantly higher by a direct investment in btc.
I think you are underestimating the intelligence levels of miners... Sure you can find single cases that support your statement, but the majority of the network is commercial now.

I agree that the margin for profit is small, but not profitable is not true.
Most miners has experienced both loss and gains, but that is properly not much different that any other business.
The reward for mining is self-adjusting, as long as there is a block reward to compete on, then will there be miners to race for the reward.
If the block reward exceed the cost in electricity and roi is impossible then will some miners (with lower hashrate = lower probability to find the block) shut down, and then will the difficulty go down, and then will roi be possible for others. The system will self-adjust to a level where there is a profit for the miners.
Even when all 21 mil BTC has been mined will there still be competition to claim the tx-fee's in the block.
The system (bitcoin) is on a ramp-up right now, so it is very difficult to make any scientific conclusions based the current situation, I believe a more holistic approach is needed.

For anyone to be able to answer your question, he should have every ASIC so that he can compare which one is the most efficient. You probably should rephrase your question, asking to anyone who has an ASIC miner, what is the Hash/Watts they are getting at the wall.

the word is that the KNC Neptune is the nuts, but we're still preflop so everything can change once the board is revealed.
As others have mentioned in prior responses, you aren't restricted to only Bitcoin on ASIC SHA256 chips/rigs.... If you have the time, patience and a little smarts you can do as many are right now: find a sha256 coin that you've found to be profitable with your hardware, then trade up to bitcoin, and speculate, HODL, or keep flipping. There are a multitude of recipes that may be profitable... many many variables to account for. Lots of reading.

Hi guys,
no I'm not another newbie whos thinking to get rich by mining.
I know that mining is not profitable at all due to rising difficulty caused by "mining-noobs", losing a lot of their money.
In fact I think theres acutally blowing up some kind of mining bubble. When people realise they make no profit and sell all there mining hardware the bubble could explode and rise the btc prise down. But thats just a theory.
I'm writing a bachelor thesis about bitcoin and in one chapter I will analyze if its possible to make a profit by mining.

A bit off topic but in the vein of academic integrity, since this is for a thesis. You "know" mining is not profitable but you haven't analyzed profitability yet, and want people to give you lead ins to do so.
It's one thing to hypothesize it will not be profitable, but fore knowledge is dangerous.

Hi,
A direct answer to your question would be a stolen one using somebody else's power. $:MH/s ratio would be infinite and running costs would be nil. Any bitcoins mined would be profit. An answer you're probably looking for though is the KNC Neptune.
It's also worth bearing in mind that Bitcoin is not the only cryptocurrency you can mine. There are many others, and more importantly, many others that can use the same hardware to mine. These smaller crypto-currencies, along with the benefit of easy to use exchanges may pose opportunities to the small fish.
Good luck on your thesis. Rather you than me.

knc neptune in terms of $:GH/s is less advantageous than terraminer iv but both have shipping very late.

i've a small stack of garden blades (8gh-10gh per blade) they run around 80-90w per blade.
old tech but decent.

Looks like xtrememiners is scam. Don't get near it.

I'm writing a bachelor thesis about bitcoin and in one chapter I will analyze if its possible to make a profit by mining.
Also I want to calculate how much it costs to mine one singe BTC (power costs + proportional hardwarecostes). Therefore I will make the assumption that only the most efficient (hash per watt) mining hardware is used.
So what is the most efficient hardware available at the moment? It's important that it has been already delivered to some people. I don't want to calculate with one of those preorder hardware minng, which may never arrive.
Thanks for helping me out.
