#2He passed away months ago. RIP. He seems like a class act from what I’ve heard.

I really hope I live as long as these guys. It's one thing to invent something useful, it's another to spend your life watching it grow.

#6This is the Dennard of Dennard Scaling, a chip scaling law that is arguably as important as Moore's Law.

The end of Dennard scaling was why the Pentium 4 architecture was a dead end and never hit 10Ghz like it was supposed to, why the Cell processor never hit the 5Ghz it was supposed to, why we've been spending quite a bit of the transistor budget on more cores rather than a very fancy single CPU core of 10Bs of transistors, and why chips with lower thermal limits will see a lot of "dead silicon" where you can't actually light up the whole chip at once without melting it.

Roger Penrose is 93 and as sharp as a tack!

Dennard scaling, for people in the industry, was far more important than Moore's law when it was available.
Moore made a high-level observation, but Dennard told you how to do it.

#9RIP.
I was surprised that it didn't get much attention on HN when the news broke back in April, considering Dennard's large contributions to technology.

Well, it's basically the technical implementation of Moore's law, since Moore's law is just an empirical observation. (And maybe also a self-fulfilling prophecy)
