@eniko Tom’s Hardware have a review that compares it with some lower-end discrete GPUs down the bottom of this page: https://www.tomshardware.com/reviews/amd-ryzen-7-5700g-review/3 and you can potentially extrapolate from there?
If you don’t mind waiting a few hours I can do some background research properly, chuck together some tables and add up a bunch this stuff to give a wider range.
