I wish mainstream CPUs / GPUs would focus on power

I wish the EU would start rating PCs by their energy consumption, perhaps accompanied by an energy tax for the worst categories. The amount of power in a modern PC from CPUs & GPUs wasted as heat, fans etc. is just ridiculous.

Everyone pays for the power they consume, be it gasoline or electricity. Who cares?

Exactly. Who cares? People are generally selfish and sometimes you must do things that benefit people as a whole instead of individuals. If slapping a tax on the most energy consuming devices in some category causes people to buy the more efficient ones, that is a benefit to every one. If you still want to buy that device despite the tax then nobody is stopping you. But I guarantee that for everyone who does than many more will choose one which doesn't.

It does not mean either that you're getting a crappier machine as a result. While there is a relationship between CPU / GPU performance and power, I doubt it is a 1:1 mapping. Some processors and GPUs are going to deliver more operations per watt than others. Companies and consumers should be encouraged to favour the more efficient designs over the less efficient designs and a tax for the worst offenders in any class is one way of going about that.
