4090 isn't that much higher than the XTX (I also have the XTX), it's 1008GB/s (4090) vs 960GB/s for the XTX's.

The 5090 destroys both at 1792GB/s.

It's not really one thing with the nvidia cards best I can tell it's that they compounded incremental gains from software drivers, card kernels and optimization from been the primary choice (plus first mover advantage).

I didn't buy the XTX for AI purely gaming but it's a capable enough local card for running Qwen et al.
