I did not say AMD has given up. What I have said is that they and other tech websites that AMD is no longer in the high-end GPU market. Where are you getting your information that they are targeting the 6090?
I'm hedging that Steve Burke from GN is correct that AMD is no longer in the high end GPU market. As Steve mentioned in one of his videos, that AMD doesn't seem to believe in their own products when they abruptly asked how they should price the 9000 series, two days before launch.

So you are wanting us to believe that after the disappointing sales strategy of the 7900XTX (which compared to the 4080 and not the 4090) and the scattershot launch of the 9000 series that they are going to somehow do an about face and leapfrog the 6090? I hate to say it but I no longer buy city bridges from scrupulous sellers.
Your opinion just runs counter to what Steve Burke says the market segment AMD has settled on and it is in the mid-range market. AMD still has supply issues to this day because as Steve Burke mentioned, they didn't build enough capacity because they didn't think the 9000 series would be popular. So again, he was correct in saying that AMD doesn't believe in their own product.
Meanwhile Nvida's 5000 series cards are dropping in price and getting closer to MSRP on Amazon. In fact they were recently selling a 5070 Ti for $749, while the 9070 and 9070XT are still 30-50% above MSRP.
