While blaming anything and everything on "capitalism" is disingenuous, it really does have to do with a lack of competition in the space. None of the incumbents have any incentive to really put much effort into improving the performance of gaming GPUs. PC CPUs face a similar issue. They're good enough for the vast majority of users. There is no sizable market that would justify spending huge amounts of money on developing new products. High end gaming PCs and media production workstations are niche products. The real money is made in data centre products.

I don't agree. It is capitalism, but not in a bad way. Simply put it is economy logic. Chip market has shifted from consumer market to the enterprise market.

So because the supply is limited, the demand has gone way up, and enteprise market has a lot, a mean a lot of money to spare buying, because it is an investment for them and not entertainment.

Also some bad capitalist tacticts in other areas, hard drives for example, that the big players reduced production to keep prices from falling. They cotribute to the problem, but they are not the major factor.
