Most power efficient asic (that's been confirmed to be shipping)

[Mike Amato]

So many different manufacturers, each having a few models with several mining configurations that can significantly change the GH/w. Is there one clear make\model that dominates or is it a disputed title?

ASIC only, or complete mining machine?
If chip only, than it's A1 from bitmine.ch.

Actually I assumed the two would go hand in hand (the most efficient chip being used on the most efficient machine). However, now that you ask I guess it really doesn't.

What is the most efficient (GH/w) complete mining system at least 100 GH/s?

Currently, Redfury USBs are 1 watt:1 gigahash. But thats only 2.5 giga.

Antminers are 2:1, 360 watts for 180 giga.

I've heard rumors of a new avalon machine that is 950 watts for 1 terahash that should be out in a few weeks

peta mine is a januar customer  i love bitmine.ch great swiss company!

Bitmain AntMiner S1. Easily overclocked to 200 GH/s and draws 400W at that speed.

I just got my S1 a few days ago. Bitmain have them in Stock and they ship them within 2 business days of payment.

i hear good things about knc miner https://www.kncminer.com

forget butterfly labs they have a bad reputation

also buy in fiat, you will cry if you buy in btc and the machines are delayed while btc prices go up

the more the btc rises the bigger the incentive is for the asic manufactures to hold the machines to mine for themselves.

the 2 TH from cointerra maybe?

[libitum]

What matters is the asic technology and clock speed.
Cointerra and KNCMiner are the best ones right now because of their 28nm asics. With those you can get 1-1.2 Watts/GH.

BitFury, Bitmain, ASICMiner are using older asics.

KNCMiner will start shipping in 3 months its Neptune (20nm ASIC). That is the only product with 20nm planned for 2014. It aint cheap though. $10k for 3TH @0.6-0.7 Watts/GH.
Here is a review of KNCMiner and their products if interested.
