30% hit to performance isn't the same as 30% hit to power. Right now, I'm typing text into an HTML textarea element. Most of my laptop's power is going to the LCD backlight, I would guess. Dunno, though. Maybe some tab in the background is sucking up 100% CPU not doing anything, in which case, power consumption is the same. In one scenario, that tab is sucking up less compute. If you're sitting in a cafe, using your laptop to train machine learning algorithms, you might lose 30% battery time, but you're probably doing something wrong. And I would gladly pay 30% more on my AWS bills for more reliable machines. It depends on what you're doing, but for what I'm doing, server costs are a rounding error in our budget. Most money goes to people. But I don't think I'd pay 30% more in AWS bills since a lot of what they do is IO-bound and not CPU-bound. I think the tougher calculation would be on GPUs. At least for what I do, on the rest of the computer, it's a no-brainer.
