Extra power consumption means extra money and/or bulk and/or noise on power delivery and cooling. Then all that heat ends up in my room which is undesirable for ~60% of the year.
- p1necone 5y agoNot necessarily if its also faster - something taking 5 seconds at 120w draws the same amount of power as the same thing taking 10 seconds at 60w on a slower but less power hungry CPU. Try measuring the at wall power draw of your PC while doing some standard tasks + when idling/light web browsing and extrapolate out to monthly power bill - you'll probably find the cost to be pretty negligible even with more powerful desktop PCs. (Of course none of this is an argument in favor of this particular CPU which has both high peak power draw and worse performance per watt than its competitors).
- scns 5y agoTrue, it is called the race to idle. A lot of work went into transitioning between pstates really quickly. A counterexample would be one commenter here on HN, who got the lowest clocked, highest core count server he could get his hands on, for zipping through the compilation of C++ projects.
- Koshkin 5y agoUnfortunately, performance never scales linearly with power (nor, actually, does it scale linearly with the core count).
- p1necone 5y agoNo, sometimes it scales better, sometimes it scales worse. It's all about finding the efficiency sweet spot of the specific chip and workload.
