Blockchain.info has a stat for mining profitability based on electricity consumption of 650 watts per gigahash. This seems like a high figure to me in the age of ASICs. What would be a reasonable figure to use, based on ASIC machines currently in use? (as opposed to vapour-ware promised for next year).

I wrote to them complained about it a month ago. No reply. The figure is 6-8 mths out of date. The energy is down to a few percent of that. 650Watt is a GPU rig figure.

The 650 W is not the problem. What strikes me is that they know about the electricity costs of 200,000 miners. :-))))) Should be anything between 0 and 45$c.

Yeah even if some use gpus for heat you may have free electricity but not free heat so running a gpu would make sense in the winter.

Most hashing is asic the number should be under 20 watts

The 650W is based on easily obtained. You know the scams on the forum, especially,the most imfamous butterfly. Before I do more seriously, I bought 7970 to test out. Even fail At last, can be for other usage such as drawing. The ASIC cannot suit for as if there was no alternative nor improved one, it is just waiting to be broken.

Don't even bother anymore, but, say, back in March or April, I'd look for cheap 7770+ on slickdeals and buy, do rebate, sell games... mined with them from about 2 weeks to 3 months (depending on when I bought it)... but even now could sell them for about same value as they cost when bought new.

eg; the two 7790's I got for around $75/ea after doing rebate + selling game/app they came with

Thanks. Yes I saw that some of the 2014 ASICS are promising 0.6w / GHS. So blockchain.info are out by a factor of at least 100 and possibly a 1000.

Think for yourself

That must be a really old stat. Block Erupters consume around 7.5 Watts per Ghs.
