When i first heard about it in Vegas I was a shocked to see sub 10 W/TH. From a technical standpoint definitely impressive. I always expected Moore's Law wouldn't hold at *some* point due to quantum tunneling and other physical limits, but it seems like we're just not there yet.
If you are writing about ASICs with hydrocooling, then look at the engineers' reviews about them. The quality of standard containers is not the best, and after several serious mistakes, engineers come to the conclusion that they need to make their own solutions.
