Because the demand for AMD graphics cards has never been all that great. AMD cards languished on the shelves when there was no RTX card to be found. I mean the RX 6650 XT can be found for the price of an RTX 3050. They have been that price for a bit now. If price to performance were a thought to the majority of people buying cards, there would be no way that would be the case. Obviously, gaming performance is not the only consideration. I've been wanting a new graphics card for some time now. I won't pay the Nvidia/miner tax and AMD does not provide one with easy machine learning access.
