Very nice review, seems to be a good competitor for the L3+

Wonder how did do 900W @28nm instead of Antminers 800W @16nm...

Really would like to get my hand on some of these Wink

Also send you a PM

I'm pretty sure that BM1485 chip in L3+ is 28nm node process  too.

Highly doubt that. Most likely all their lineup is L3+/S9/D3 is done on same process to cut costs. Most  likely they are also very similar, most differences coming into chip codebase.
Your argument is invalid, it is actually cheaper to make 28nm node process chips.

Bitmain is not mentioning the node process any where visible. If it was 16nm they would use it in advertising just like they use it a lot in the Antminer S9 advertising.

I tried a lot of Google searching but I was unable to find which process BM1485 is done.
