Hmm, I take it someone forgot about Canaan and their A921 which came out last October?
Very stable BUT - unfortunately its efficiency is just barely better than the A841.

actually i can downclock an a841 and do 900 watts and 10th which is 90 watts a th.
just a tiny bit better the the a921 as it still has firmware issues.

I have yet to see that bitmain has a bad chip I suspect the psu has been its issue.

and the 10nm innosilicon that says it does 48watts a th is yet to have full shipping and testing.
the ebit e11++ claims 1980 watts at 44th and I can't get one to test or demo

but 1980/44000 = 45watts a th for a 10nm chip

if someone shows it I will believe it.

So for now while I really am not a bitmain fan the s15 at low speed is 900/18000 = 50 watts a th as demo's by a few people .

mine will come by friday I pruchased a used one to confirm it does 50 watts a th .

if I can get an e11++ to test and demo i will do so
if I can get an innosilicon terminator 3 to test and demo.
