I just don't relate to a company selling goods or services in a competitive, international market who is reticent to deal with certain markets that apply different metrics of all kinds. Sure, it's PITA in terms of effort and expense, but that's just part of bu$iness. That for your most lucrative markets, expect to accommodate your customer base to some extent.
I can only surmise that for companies producing products using less common metrics to explain their performance are either just plain arrogant, or doing as such to possibly obscure their specifications given their competition. To discourage consumers like me who are willing to look up and analyze such things to make an informed decision over which product to purchase.
Yet when you look at some of the "mega" corporations like Nvidia and Microsoft, you know they are openly treating their customers badly at best these days. Preferring to tantalize shareholders based on promises of profit over AI technology.
Yet conversely there are companies out there like Thermalright based in Taiwan who is a direct competitor with Austria's Noctua, making a broad selection of quality cooling devices for computers for an astoundingly lower price. Who use all the most common metrics allowing me to understand what their specifications truly mean.
But Noctua does provide one critical quantitative piece of information that keeps me using their expensive CPU cooler. While their explanation of thermodynamics deviates from TDP specifications, they make it abundantly clear that my NH-U9S Chromax Black CPU Cooler delivers superior performance when used with an Intel i7 CPU, overclocked or not. Especially given that 1) I never overclock A CPU or GPU, and 2) that I have an Intel i5. So I feel comfortable that this small, but expensive CPU cooler is more than up to the job of mostly net surfing and perhaps occasional gaming.
Bottom line: If you want to build an efficient computer, yeah....you have to do a lot of in-depth research:
