I don't know of a comprehensive table anywhere.  The documentation for
Racket's R5RS and R6RS compatibility layers has some brief comments on
differences:

If you look on the Racket blog, you can find articles on specific
deviations from Scheme such as avoiding mutable pairs:

Off the top of my head, I can't think of any good articles that broadly
and explicitly compare Racket and Scheme. However, several articles have
addressed "why Racket" such as these:
