One of the impressive things about chips ever since the 70’s, is how they’ve become ever denser and ever more powerful, so they are now more than 50 thousand million times more complex, going from little more than a thousands, to 50 billion transistors as per 5 years ago! Yet modern chips remain very reliable, and the biggest vulnerability is not inherent, but from targeted hostile attacks against them.
Yeah… chip designers have been battling heat output since silicon doping was invented. The main source of heat is transistors changing state, since it doesn’t happen instantly, and will disipate more heat when half-on, acting almost like a resistor.
The higher the clock speed, the more time a transistor spends half-on. This is why things like undervolting and underclocking reduce power usage.
Physically smaller transistors usually also means it takes less electrons to saturate the gate, so it allows lower voltages and currents to be used, while still toggling the state at the same speed. (Not to mention timing gets easier the closer the transistors are to each other)

It's almost as if the industry knows very well what they are doing.
Which is also why thermal limit has gone up, and they they introduced throttling and such. It's like they're aware of the problem and working on it... but that wouldn't make a nice article.
Yes absolutely, I don’t know how they do it, but I remember BIOS shutting off the computer if the CPU was 60° C. Now many chips can handle above 100° C.
Article didn’t mention this DOE project. All major chip companies are collaborating, plus colleges.
Essentially, the military has tech that can be ported to the civilian side. Applying it to future gen GPUs will shift the data center liquid cooling industry.

Thank you
You’re welcome.
I’m going to go out on a limb here, and say the multi billion dollar corporation has probably thought about that.

The headline is moronic, but of course the progress of chips will slow down, and heat is one of the factors.
