If we assume this design is based off of something similar to the 28-core 8180 which has a 2.5GHz base frequency and (generous, likely understated) 205W TDP, this chip could easily have a TDP north of 300W. Those boxes on stage sure don't look air-cooled to me. The plumbing seriously resembles that of a phase-change setup, which would actually make sense here as an extremely low operating temperature would help tame the leakage power tremendously. In summary though, it ain't gonna be cheap to buy or cool.

I'd willing to bet that it is very different to 8180. it is simply not practical to boost freq from 2.5 base/3.5 turbo to all cores 5Ghz.

  I think the cooling could be a significant part of the picture here---you can nudge the power/frequency curve a bit with very aggressive cooling (phase-change is extremely aggressive) to drop the leakage power (e.g., as AMD did with the liquid cooled Fury X [1]). If this had a different core count from the 8180 I would agree but I wouldn't expect Intel to do a completely separate design just for a model that will need to be highly binned regardless. That or Intel has made some serious magic happen at 14nm++++++++++.

      12nm is not a substantial gain over 14nm.

      I'm more interested in Zen2 on 7nm which seems to be coming out earlier than Intels 10nm CPUs. Possible IPC enhancements from architecture optimizations of Zen2 + better clocks = first time since over a decade that AMD beats Intel in single threaded workloads? Due to their better SMT implementation (?) they seem to beat Intel in multithreaded scenarios already with same core count and around the same clock (at least in Cinebench).

        Yes, Zen2 will be very interesting to watch next year. The only problem is that AMD has not offered anything else other than some ppt presentation on how great is the Zen2.

Well it's a phase change system you can just use it to power your home steam engine.

Apparently Supermicro had some X299 motherboards on display that were rated for 300 watt CPUs. So it sounds like you're on the right track. Though I don't think phase-change is really suitable for a consumer CPU. I would think it's just going to be bundled with a big integrated water-cooler (a bit like AMD's FX-9590 CPU which was a 220TDP part)
