Another round of speculative-execution vulnerabilities

So, as farnz says, you appear to have completely mis-understood my argument and are arguing against a straw man.

Signals are carried by photons (or em waves, same(ish) thing) so the speed of light IS relevant, although from what others have said the telegraph effect is probably more important, and

My argument has repeatedly been prefixed with "IF components need to communicate" so okay, I'm not necessarily talking about clock cycles, but a single communication cycle has that upper limit. I'm not always clear in what I say, I know that, but if you make no attempt to understand me, I can't understand you either. So IFF a communication cycle equals a clock cycle, 5GHz is the maximum clock possible between two random components in a chip. Of course, splitting a communication clock cycle into multiple clock cycles can speed OTHER stuff up, but it makes no difference to the speed at which a signal travels across a chip.

(And of course, without communication a chip can't work.)

Cheers,
