Let's move on from the cost of physical goods bit going up. We all agree it has, and that it's a factor, and we hopefully all agree that it's next to impossible to judge just how much of one from the outside. Given the product and sales model it's just really hard to ever get that bit accurate from the outside, and even if you could, it'd just be accurate for that point in time most likely because it moves about a lot. Plus we argue about it too much and that makes me (genuinely) sad. There's literally zero need to argue or have negative feelings towards other human beings in any discussion about posh sand that draws pretty pictures.
Instead, how about some positive discussion about the other bits that your money is paying for when you buy a GPU. The main thing there is even less tangible from a cost analysis or value point of view, but much easier to reason about the value from the outside because it's a key part of the value judgement for a consumer, which we all are (even I buy GPUs): the value in the software.
Part of the money you hand over pays for that, and it's not just the client 3D API drivers and whatever extra user experience software you get (snazzy control panels for settings and tweaking, streaming software, etc) to run the GPU in Windows, which is the main bundle of make-it-run-games stuff most people care about, but the engagement with game developers, tools, engine middleware development, alternative platform support (I'm typing this on Linux, and very much value the great Linux driver support from my preferred GPU vendor, as an example).
I've spent some time on some (hilariously toxic for the most part, might need some therapy to get over it) tech publication Discord servers recently, taking the temperature of how their readers/viewers feel about the various recent GPU stuff going on, to get a different perspective than here on Beyond3D. Most folks interested in tech to the point they want to discuss GPUs in any detail, outside of playing games on them, also care a lot about what the software gets them.
For people leaning green that means things like considering what set of DLSS tech is supported and whether the new DLSS has unique benefits on the new products. Whether Reflex works well. Are their favourite games going to get integrations of the bespoke ecosystem things Nvidia provide. Those kinds of things are factored in to real-world assessments of gaming GPU product value by people spending money on them quite a bit, and are directly paid for by the money you hand over.
You don't just buy the physical good, and part of convincing a customer to hand over money is the aggregate value of the other stuff that enables the posh sand to draw its prettiest pictures. Maybe we can have a go at that part of the value judgement.
