Lilac is an AMD dev platform, it’s used to do early development before you have the real platform in hand to work with. It’s been spotted in the wild running 7700 HS, 8500 U and Zen3 embedded <55W SoCs - there’s no way to extrapolate new steam hardware performance info from this reliably.
Yeah, that was my thinking too. Lilac is a generic enough platform that OEMs can do the bulk of their platform work with a lilac dev kit before they have real hardware in hand for the last 10%.
Valve hasn’t even announced their own steam machine yet have they? I’d be betting on ASUS to be first to market with whatever’s in the pipe from OEMs.
