Yes with identical hardware and settings , both programs must have the same
intrinsic playing strength , however with a more optimised book it would be
possible to have an higher rating.  The problem with very high ratings on
playchess.com is often the player's "incestous" formula , often playing the
same people time after time, perhaps creating a kind of isolated grading pool ?
I experimented with 2 accounts , which had the same hardware,settings and book.
The "no rating restrictions" had a grade of approx 2500 , while the more
 "restrictive" was 2700+ , that's clearly nonsense !
