Do 7 nm chips are more energy intensive than older 100 nm?
Or it's just scale, more chips to manufacture, more energy needed.
Cutting edge chips consume more electricity to manufacture as there are a crapload more steps than older fabs. All chips are made on the same size silicon wafers regardless of the fabrication process.
Gamers Nexus has some good videos about chip manufacturing if you are interested
