Does it really matter? For me the answer is no as long as they price it correctly. Don't charge $2000 for a card that doesn't actually have that power. For instance if the 5090 was only as powerful as the 4090 but because of a couple of added "chips" are whatever they add to these cards, the 5090 can produce double the frames from software, and that software isn't able to be run on the 4090 card. In that case, the price of the cards should be similar with a small bump in price to the 5090 for the added "chips". But it should not be treated as a card that can natively produce those frames. And the price should reflect that inability. As long as they are straight up about what the card does and doesn't do and have some honesty in the pricing, I say let it rip and everyone enjoy themselves.
