Well...I just finished running numbers using my own historical production figures, actual costs, etc. I don't use any online calculators, BTW...I rely on my own math and the personal confuser. I come out with an ROI of about six months on free power (which I have at home), and about seven months at Labrador. When we were hearing speculations of "10-12TH on 1800W" it translates to exactly what we have, except divided into much more manageable units. The ROI would be the same.
Anyway...when you consider that this unit promises to be magnitudes better in build quality and maintenance considerations, I don't think it's disappointing at all. No, I'm not a large farm. Consider how many more people out there could afford to mine, though, as individuals...and it is the individual who will make Bitcoin perpetual. I have, however, run large data centers in my years...I wouldn't mind a few racks of these at all.
I'll take any further discussion to the other thread, I guess. Back to "work."
EDIT: ...and, notice...that 900W is distributed through eight PCIe connectors...not four...so the load per connect is ~113W. Smart.
EDIT2: ...and I've been using my own numbers for the past couple of years...they have never been wrong. Could be a first time, of course...
