Bitmain purchases chips from TSMC foundry Taiwan and by the number of miner batch release dates now bitmain have become one of the major client of TSMC and they to are taking mining segment very seriously
If you look at TSMC website for the 7 nm nodes segment they have divided that into 2 stratums one for mobile chips and the other for high computing power chips so they are taking mining segment seriously.
Now for the speed for the new model of S9++ or S11 (whatever they name it) we have to calculate the computing power for chips of newer nodes according to TSMC website they have started the tape out of nm 7 nodes in April and by the end of this year they will supply these 7 nm FinFET nodes to more than 10 customers and surely Bitmain is one of them.
Now come to speed of that 7nm miner we know that S9 speed is 14 ths with power consumption of 1372 watts
By looking at the 10 nm nodes efficiency according to TSMC website they are 15 % faster and consumes 35% less power so for a 1300 watt miner the speed would be 14×1.15×1.35 =21.73 Terahash for around 1372 watt miner
And if bitmain decides to skip 10 nm nodes and go straight for 7 nm nodes which I personally think they are planning and to raise funds for that bitmain is also issuing an IPO of 200 million $ in USA the speed of that ultra fast miner would be again according to TSMC website the 7nm nodes are 20% faster than 10 nm nodes and consumes 40% less power so the speed of that miner will be 21.73× 1.2 ×1.4 =36.50 Terahash and that to hypothetically
So 75 Terahash with 1200 watt is not possible
And if a 35 th miner is built by them that uses only 1300 watts they have zero mind you zero financial incentive to sell it to us. As they have a thriving hash nest business. And the s-7 makes good money and the s-9 makes more
So if the s-11 was built suscessfully in April they will simply sell s-7 and s9 hash on hashnest while they mine it with the s-11. They will lower the power a penny or two. People will buy more s-7 and s-9 hash.
Once it is jan or feb of 2019. They would sell it to us.
And frankly I think it is 100 percent sure they will not have a working 7nm chip faster then Intel since Intel is about 50x the size of bitmain.
I would not even talk about 7nm chips until Intel builds one that works.
Samsung would also come to market ahead of a Ming ASIC chip as the wealth involved is 50xor more then bitmain. .
