cryogenic cooling tho?
- chias 5y agoWouldn't solve the problem. Basically you need the integrated components to have shorter transition times. These are an inherent property of the component: speeding up the transition time basically means "replace this component with a different component that has a shorter transition time"
- dragontamer 5y agoOvervolting the component and sending more current to any transistor tends to speed it up, though at the cost of severely more watts used. Overclocking is often a combination of overvolting (leading to more amps), allowing you to increase clock speeds.
- R0b0t1 5y agoOvervolting is how this is solved and works with adequate cooling.
- zeusk 5y agoGoogle propogation delay, your pipeline's length and delay of devices within that pipe determine the max frequency your circuit can run at (a very high level overview).
- kingosticks 5y agoHow is pipeline length related to max frequency?
- enchiridion 5y agoPhysical length the signal has to travel.
- amluto 5y agoIt’s related indirectly. A longer pipeline tends to result in shorter stages within the pipeline. (This is the whole point of pipelining.)
- kingosticks 5y agoOK, yes there's often correlation but that's it. A longer pipeline doesn't affect max circuit frequency. The other sibling comment regarding distance isn't true. regardless of how insane your feedbacks are. Physical placement tools have always handled this in my experience (as a chip designer for 10+ years).

- u320 5y agoThere is no point of lengthening the pipeline if you don't get higher frequency from it. It would just add complexity and and a higher branch mispredict penalty.
