I wonder how much of that flattening is because chips are now hovering just under the 5GHz/6Ghz wifi frequencies.

Yes we have techniques that help them avoid each other, but it seems like it would be enough of a tech and PR hassle that companies wouldn’t bother.

pretty sure it has something to do with speed of light divided by clock speed

Pretty sure it has everything to do with heat dissipation

probably true as well.

also iirc the actual clock of the logic gates is a factor above the 'operations clock'

I hadn’t even considered that there is a physical limitation.

I’m too lazy to look it up now, but when I first read this I feel like the math said electrons can move at maximum 5cm in a single 5GHz clock cycle?

That’s wild.

the eletrons do not have to 'move' the entire way for transfer of information because they will push the already present ones further.

Well yes, but that’s an academic difference unless you’re stating that they can transfer information faster than light.

well no, i was saying that the information moves faster than the electrons. speed of light in vacuum remains unbeaten afaik
