Not necessarily, no.

You can pick and choose your comparisons, and make an incease appear or not.

Take weather forecasts as an example. Weather forecasting uses massively powerful computers today. If you compare that forecasting with the lack of forecasts two hundred years ago there obviously is an increase in power usage (no electricity was used then) or there obviously isn't (today's result is something we didn't have then, so it would be an apples-to-nothing comparison).

If you say "the GPUs are using power now that they weren't using before" you're implicitly doing the former kind of comparison. Which is obviously correct or obviously wrong ;)
