TSMC can only make about as many Nvidia chips as OpenAI and the other AI guys wants to buy. Nvidia releases gpus made from basically the shaving leftovers from the OpenAI products, which makes them limited in supply and expensive. So gamers have to pay much more and wait much longer than before, which they resent. Some youtubers make content that profit from the resentment so they play fast and loose with the fundame…
Also, in some sense there can be some fear 5090s could cannibalize the data center hardware in some aspects - my desktop has a 3060 and I have trained locally, run LLMs locally etc. It doesn't make business sense at this time for Nvidia to meet consumer demand.
