Hmm you say it works with 4 blades sounds like a 2 TH/s S7 or S6 is coming soon S5 is sold out at the time of this post. we just have to wait and see.
I would like to see 3+ Th S7. )
Mix that with around 1k watts and I would be pretty happy with specs. A lot is it's efficiency that matters to me.
The LKC (or something close to it) is supposed to be 14nm, 5TH at 1kw, I would expect bitmain's next product to be close to those numbers, or 2.5th at 500w, something like that.
