What is power consumption?? They say: " power consumption ratio is 90W/T "

- what does "T" mean? "per Thash"? Is it 90W * 18Th = 1620W? Or just 90 Watt ?

T is Terahash. There's no way it would be simply 90W. W/T is a common way to express miner efficiency nowadays, sometimes preferred over W/GH in the product description for some miners. I still prefer good ol' W/GH over W/TH but that's just me.

so it is 1620 Watts , - why so much?? - nearly the same as S9. But 10nm should be much more efficient as 14nm, shouldn't it ?

No. A smaller node usually means less power consumption, but ultimately in the end a better-designed ASIC is what drives power consumption down. The best example of this that I can think of is the Pangolinminer/Whatsminer- it is made on 28nm but squeezed out still more juice out of the aging plaform. Just because the number is smaller does not mean the miner will be more efficient than a miner on a larger node. Also explains why not all 16nm chips are the same- Avalon is less efficient than Bitmain, etc.

Where the chips are smaller, they can fit more on the board. More chips = more hashing power, but it also means more power consumption.

You are kidding right?
