For most users of ML frameworks, results take priority and there isn't much they can do about AMD's shit software and unreliable support. Plus even 4090s aren't really that expensive relative to what ML people make.

That said, Intel might actually be able to compete once their drivers have caught up. Unlike AMD, who seems to have systemic issues (not to mention fatal design flaws in ROCm in general), Intel just needs time because they clearly rushed the devices out before the drivers were fully ready.
