You are heavily fanboy-ing here. XTX is much slower than that:Beside the Whale tier of the 4090, AMD is kicking Nvidia *** in performance on all segment.
The only titles AMD is having problems with are the Nvidia sponsored titles that are RTX showcase that are literally sabotaging AMD drivers to cripple performances, for example Cyberpunk and Alan Wake.

The XTX is 900$ and barely 15% slower than a 4090 at 2160p with a slight OC while the 4090 cost the double.

NVIDIA's new GeForce RTX 4080 Super introduces a noteworthy $200 price reduction compared to the non-Super 4080, placing significant pricing pressure on AMD's RX 7900 XTX. Despite this, the performance gains vs RTX 4080 non-Super are only marginal, we expected more.
Even AMD said that 7900XTX is a 4080 competitor.
And looking at raster performance only in 2024 is just stupid. More and more games has RT elements and upscaling is here to stay. DLSS beats FSR with ease.

Another AMD issue:
