Well, looks like AMD is following Nvidia in their confusing naming. A 100$ difference, but at a cost of 4GBs of VRAM? Same thing happened with the RTX 4080 12GB vs 16GB controversy (RTX 4080 12GB was a big compromise in other areas as well), but it seems that AMD took notes and named this as XTX and XT. Anyway, 20GB of VRAM is still plenty enough for gamers, and we'll have to see 3rd party tests to see what sets the XTX and XT apart.
