Largely agree with this in terms of hardware power consumption, however there are some key factors missing, specifically in terms of operating system architecture, software and related background processes which have been largely introduced in this time frame as well. A prime example is YouTube and hover over playback. My pc will "idle" at around 35 to 40 celcious (11k series intel cpu with no graphics capabilityon ks format) depending on ambient room temperature, simply mouse hovering over a video preview, I consistently see 50c or more on the cpu while the preview plays. This is akin to temperatures I see at gaming loads and other render heavy operations. Windows has also become a hungry data "grabby" power hog, but I suppose it takes a lot of cycles to scrape all that user keystroke data etc., etc. Nvidia and their multitudes of containers also take a toll, the list goes on.
A little background on my own recent machine upgrade, self built and admittedly power hungry even with power settings and clock rates set to "default" in most cases. I don't game much if at all anymore and a lot of the joy of building was lost after this last one. I was among the archetype of the over clocking crowd for some time. That being said I learned a lot from de-lidding, understang RAM clocks, how it relates to ras, cas operation, rops etc. In a way it forces you to understand the minutia of the "little" things, both hardware and software related that bottleneck that "5%" gain in performance. Over clocking was for a time my forum of social media where I could hash out my design process with other like minded people doing the same.
(Opinion) This all feels like a push to box folks into largely terrible pre-built machines which themselves aren't efficient for what they provide in performance, more flagrantly it objectively feels like the home pc is being purposefully erroded into cloud access nodes, vm boxes etc. There are tradeoffs some positive and negative but again feels like an industry play to push cloud enforcement and further user research, testing, data storage strategies etc. Sorry if this is ranty its just been a thorn in my side over the last few years, and it feels exponential.
