I mean the 3080 was $699. Why would them suddenly raising the price for it's successor by $500 lead to good sales? There should be no surprise at all that the 4080 isn't selling well. When your price increase is proportional to your gen over gen performance increase that means its literally zero performance per dollar increase gen over gen for the 4080. 4070 is clearly a misbranded 4060 Ti in reality for $599, again a rip off. And the 4070 Ti has all the performance characteristics of a real "4070" as 70-class products usually matched previous gen flagship products and the 4070 Ti does this. Yet again, $799, so grossly overpriced, and again, misbranded - just maybe not as poorly as the "4080 12GB", but still misbranded.
The 4090 is the only good selling 40-series product. And my opinions about 90 cards being a rebrand and successor to the 2080 Ti in the last 2 gens with a massive price hike again aside, it's at least a great performer that really is unmatched and remains the only card in the lineup that they didn't actually try to massively raise price on from last gen. Yet it is still a cutdown card and I don't think they have any reason to release a 4090 Ti given AMD's current showing.
All I can say to Nvidia having poor sales is: GOOD, hope they learn something, and couldn't happen to a more deserving greedy company that is now more interested in being absolutely predatory with misbranding and pricing. I am an enthusiast of graphics, doesn't mean I have to be ok with how they are trying to price everyone out of it and ultimately give the average joe who doesn't buy the top end halo product for the price of what one not very long ago could build a whole high end/enthusiast grade PC for, every gen ultimately less for more.
So Nvidia poor sales? HA!
