We could wait a little about power consumption.
The node shift is unable to halve the power consumption on an high power cpu, moreover half the SKU is on 14nm.
More likely AMD demoed on a very light development motherboard unable of overclock. My bet Intel was on a power hungry plataform thinked to allow more than 300W under overclocking.

Better wait real products.
For now is only smart marketing.
