The blackwell chips sell for ~$30,000 and have about 1600mm^2 of silicone. $18.75 per mm^2
The RTX 5090 chips sell for ~$2,000 and have about 744mm^2 of silicone. $2.69 per mm^2
nVidia has little incentive to make very many consumer grade chips to sell to AIB partners. This means that AIB partners are not going to be able to sell very many products. But they still have to do the research and development as well as tool up those designs, and that all costs money, that has to be recovered as they sell the end product.
If they can sell 100,000 units, that cost can be divided by 100,000. Then it can become a trivial part of the cost and they can sell cards at MSRP.
If on the other hand, they can only end up selling 5,000 cards, then the cost of the Research and Development and the Tooling is 20 times as high per end product sold. That cannot fit inside of the MSRP envelope any more.
Consumers are getting hit, producers are getting hit. The only entity prospering off this currently is nVidia, and that is exactly what their job is. Make money. Your feelz are not much of a concern to them. $130 billion in sales while consumer products make up ~$15 billion means you are not important. And, it is not like they could not sell that silicone for $18.75 per mm^2 to someone not you.
It sucks, I think AI is a scam with smaller return on investment than it costs to create and use, but currently it is the market, and we consumers are not.
