BTW, one more thing... Both HashFast and CoinTerra cannot produce performance-per-electrical consumption that Black Arrow claims they could. So, I'm getting even more skeptical...
CoinTerra TerraMiner @ 2 TH/s consumes 1,650 W
HashFash Sierra Evo 3 @ 2 TH/s consumes 2,200 W
... as for Black Arrow Prospero X-3 @ 2 TH/s, they claim 1,050 W. Either this is a blaten lie and scam, or they have super engineers.
Why are you so dedicated on spreading misinformation?
Both cointerra and hashfast have had much longer delays than BA and underperforming hardware. It is a bit hilarious you seem to think bfl/ct/hf are any sort of gold standard when it comes to asics.
BA has advertised 0.6gh/w for the chip alone. So that equates to around 1000w per TH for the complete miner.
BA has just announced successful tapeout confirmed by verisilicon. Care to comment on this?
Btw asicminer next gen 40nm chips will be 0.2w/gh. Does that make you skeptical?
