What does this mean? How does this affect home miners? Will difficulty shoot up soon due to Bitfury 28nm chips?

The chips are reported to perform at 0.2J/GH, which is a pretty substantial achievement. Once the chip is fully developed / market ready, you can bet all of the big farms will want to incorporate it as soon as possible. It will drive their energy requirements down, allow them to expand, and, as a result, ultimately drive up the difficulty. How long it takes to get to this point, or how high the difficulty will go, is hard to say.

The consumption at wall is not yet to been seen (otherwise we would have seen their mining board)

Very true, and the difference can be huge. For instance, the SP31 uses RockerBox 28nm chips with an advertised efficiency of 0.34 J/GH, but the nominal specs for the miner is 3 kW at the wall for 4.9 THS, i.e. 0.61 J/GH (source: SPT website (http://www.spondoolies-tech.com/products/sp31-yukon-shipping-from-stock)). Of course efficiency can be increased with underclock/volting but it will significantly affect the ROI by increasing the investment cost per GHS.

That's one of the reasons why I don't like large single chip miners, because the VRMs are a lot more intensive and concentrated high currents mean a lot of resistive losses. Spondoolies' next-gen stuff will use the same concept. It's actually pretty impressive that they can get their gear as efficient as it is and still have 100A VRMs on every single ASIC.

I thought from now on Bitfury was only self-mining with their gear....

Yes but Bitmain chips has 0.249 J some time ago efficiency at wall and cost is also important

They  also sell wholesale  to other farms/ clouds to share revenue  splits or contract  for hashrate.

Isnt this old news?

Quite true, but I imagine the "at-the-wall" efficiency would still be better than what's currently on the market, even if it ended up pulling 0.4J/GH.

As for old news, partially. They had advertised they were working on a low powered, 0.2J/GH chip ages ago, but only recently finished development and testing. Turns out they met their original projections.

They dont have time to make retail machines but will probably sell their chips in bulk if the price is right.  Being first developer with latest gen high efficiency chips give a huge advantage over the competition where they can almost dictate their price because they have invested millions in r and d.

  dictate their price?  with coins at 240-250 usd I am not so sure how fast they will sell.  Sell yes, but sell fast not so sure.  Now if knc really can do a .06 watt chip in bulk that will sell much better.

One thing I do think is growth will get a boost from this. maybe it will do steady 5% vs the 2 to 3% we did from nov. 2014 to now
