CPUs with higher power consumption are:
- Irrelevant regarding battery life because I can get from my office to the conference room to my shop to my home and back to my office long before the battery dies even with hamstrung sleep states in modern processors; everywhere I work it's plugged in to a monitor, keyboard, mouse, and wall socket and I can't understand why you would use it otherwise.
- Still quiet, because the large heatsink is able to cool it while doing little work, and a large-diameter and thick fan doesn't have to spin like a jet turbine to cool it when it does need active cooling
- Really, really cheap per hour to operate over years of critical usage; if I quote my time at $100/hr, use a computer for 40 hours a week for 100 weeks, and am more effective by even 1%, you could easily justify spending $4,000; realistically a bigger processor is far less than that.
- Still quite fast even when I'm doing real work, unlike underpowered CPUs that throttle whenever I'm actually getting something done.
so I would not work with an underpowered processor.
