4060 TI is a year old and $400 on release. And they used an outdated test that doesn't get benefits from the 4xxx series GPUs like hardware ray tracing or frame generation.
Factor in that stuff, and $250 seems like a sensible price point for people who don't want/need that stuff.
The other factors, of course, are ray tracing, which is a current unknown for Arc B580 performance, and where Nvidia is the current king, as well as compatibility.
But whether it can support it or not isn't really relevant, it's not a binary thing bruh...
