“To deliver the highest quality backwards compatible experience consistent with the developer’s original intent, the Xbox Series S runs the Xbox One S version of backward compatible games while applying improved texture filtering, higher and more consistent frame rates, faster load times and Auto HDR.”.

What this means is that most Xbox One games will run on the Xbox Series S at 1080p or below in backward-compatibility mode, though they will benefit from certain built-in hardware advantages like the faster SSD.

It’s possible that current-gen titles could receive updates just for the Xbox Series S, and this will be the case for some first-party games like Gears 5 and Forza Horizon 4.

VGC reports that the same is true of backward-compatible Xbox 360 titles, though it’s not clear what this means for compatible original Xbox games, all of which run at close to 4K on the One X.
