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 !
