If heat is produced by conductors resistance then shorter paths would lead to less heat produced.

- ben_w 4mo agoI'm not certain (never did hardware), but I thought the transistor switching cost was one of the bigger sources of energy loss, not internal conductor resistance between transistors?
- deepsun 4mo agoMakes sense, I also doubt that they haven't minimized resistance to minimum already.
- IshKebab 4mo agoYou're correct. Dynamic power consumption depends heavily on frequency, but it's definitely more of a limiting factor than static power consumption which as I understand it (I'm also not an expert) is mainly important for things like low power microcontrollers.
- saltcured 4mo agoThe shorter connections could lead to faster rise times though, right? I.e. less capacitance or inductance interfering with getting the field gate charged up? And the main loss with switching transistors is in the intermediate switching states where it has less than its "full" resistance.
- marcosdumay 4mo ago> The shorter connections could lead to faster rise times though, right? Not if you replace that length with more capacitors stacked on top of each other.
- saltcured 4mo agoHah, yeah. I've been naively assuming they are now making high quality vias, so that circuit characteristics would be similar in either vertical or horizontal direction.
