TSMC made a point of calling out that their latest generation of software for automating chip design has features that allow you to select logic designs for TDP over raw speed. I think that’s our answer to keep Dennard scaling alive in spirit if not in body. Speed of light is still going to matter, so physical proximity of communicating components will always matter, but I wonder how many wins this will represent versus avoiding thermal throttling.

EDA software has long allowed trading off power, delay, and area during optimization . But TSMC doesn't produce those tools, as far as I'm aware.

They don’t produce but they are tailored for them just the same. “We have” doesn’t have to mean “we made”. They don’t say it as such here but elsewhere they refer to the IP they can make available, which can also be made in house or cross licensed and still count as “we have”.

Used in that sense, the same software could be called Samsung's and Intel's and any other foundry's, since it is qualified for use with those processes as well. But that's not really the main point I was making, which was that there have been 20+ years of cooperative effort in both process design and EDA software to optimize for power and trade it off against other optimization goals. While there are design and packaging approaches that are only coming into use because of "end of Moore's law, what do we do now" reactions, and some may have power implications, power optimization predates that by a good while.
