Juli Clover, at MacRumors, notes that neither the new Studio Display nor the Studio Display XDR are compatible with Intel-based Macs. (I’m curious why.) Also, in a separate report, she notes that Macs with any M1 chip, or the base M2 or M3, are only able to drive the Studio Display XDR at 60 Hz. You need a Pro or better M2/M3, or any M4 or M5 chip, to drive it at 120 Hz.
