Why does everybody read something that I have not written here?
Yes, it will bring power efficiency.
But for those expecting that suddenly 250 mm2, 2560 CUDA core, GTX 1660 Ti replacement on 7nm, clocked at 1.9 GHz will use less than 150W should stop dreaming. It won't happen.
On 7 nm SS EUV? Maybe.
Basically your extremely short selling the improvements of a new node, especially when it comes to keeping things near stock settings of todays cards.
An RTX 2070 can already achieve 1930mhz at roughtly 225 watts or 228watts specifically. Not any sort of underclocking/undervolting involved.

You know what happens when you clock a card at last gens speed?
You literally cut the power consumption in half. There are AMD slides that say this and TSMC 7nm spec says this(50% reduction at the same performance).
Heck, laptop graphic chips deliver this without the nodal improvements.
Laptop variants of Nvidia GPU's are able to deliver 90% of the performance at 75% the power consumption and 80% the performance at nearly half the power consumption. So 1.9ghz 2560mhz will likely be possible at 150watts. Pascal was able to increase the shader clock by nearly 50% at the same power and 25% more shaders at the same power with between gtx 980 and gtx 1080. A mere 10% increase in clocks, with a modest increase of a 11% in shaders, will consume sustantially less than a RTX 2070. At launch, RTX 2070, with b grade silicon quality were consuming 200watts, and 1750mhz. You don't think a new node designed for high performance is not capable of raising clocks 10% and 11% more shaders while shaving 25% power? Why be so ultra pessimistic. AMD even did this Radeon VII raising stock clocks about 20%, while decreasing power consumption by 17%, while adding 2 stacks of HBM(which would add more power consumption then 4cu) and adding power inefficient double precision hardware at their first and earliest stab at 7nm. You think Nvidia engineers are so incompetent that they can't achieve the performance per watt increase of Radeon VII which had a strong compute focus while having using a better version of the node while having 1 to 1.5 years more to work on the chip? Ridiculous.
If Turing clocks at a very conservative 2.2ghz on 7nm, which some turing chips can nearly achieve on air today, it will likely consume 180 watts or less (25% increase in frequency, 10% reduction in power(B grade oc silicon) or (14% increase with a 20% reduction in power vs A grade silicon today) because it is not using the full capability of the node which turns into power savings(potential for the performance version of node is 40% increase). For the most part, next gen nodal parts are clocked better than last gens air overclocks. This is because much of the big reason for the move to the new node is take take advantage of the performance increase per transistor. That means extending the pipeline to get higher clocks. Leveraging simply the power consumption wouldn't allow companies to charge higher prices per card, hence why most companies move to it. Pascal/maxwell are designed for higher clock rates while having power very controlled which is why pascal came out so good. Considering the ln2 clocks of turing today, this will likely be extended with amphere.
7nm turing/amphere is guaranteed to be more efficient than navi because even with AMD performance slides(which are likely inflated), 12nm turing is already slightly more efficient than 7nm navi.
