I have been following Cointerra because their TerraMiner IV promised 2THs with a consumption of 1200 Watts total (0.6 Watts/GHs).
Even though Cointerra uses 28nm ASICs (the same than KNC Jupiters are using) they promised a huge improvement over the Jupiter, which consumes double the electricity per GHs (1.2 Watts/GHs).
"Early estimates of power efficiency indicate 0.6 Watts/GHs"Now that the first TerraMiner IV is out (they dont deliver volume yet), they have updated their specs to 1.2 Watts/GHs, and only 1.63 TH instead of the promised 2TH.
"The production units that we have assembled and tested so far are running at between 1.63TH/s and 1.72TH/s with power draw at the wall between 1900W and 2100W"
That means that their 28nm ASICs are exactly as power hungry as the Jupiters. Not double as efficient as they falsely promised to gain market share.
Their TerraMiner exactly equals 3 October delivery Jupiters, in hashing power (1.65THs), in electricity (1.2W/GHs) and even in price (US$ 15 700 was the price for the first batch TerraMinerIV as said in the same article).
If you are also mining with
KNC hardware (feel free to bookmark that KNCMiner website), the Cointerra news means for us:
1) the Neptunes will blow out the competition, and
2) Jupiters wont become obsolete for many many months. Jupiters will become obsolete the very same day the brand new TerraMiner IV (the one that will start volume delivery during this 2014) does, because both consume the exactly same electricity per GHs).
