Yes, but 3rd party games that were designed around the cell trounced the 360 version pretty bad. I mean…look at ff13.
FF13 ran worse because it was most likely a low budget port job.
that game should have had no issue running at the same resolution on 360 given that the 360 has a better GPU and I'm pretty sure FFXIII doesn't really utilise the Cell's SPEs much.
I say pretty sure because the game is very light when emulated through RPCS3, and games that utilized the SPEs to a high degree are also way harder to emulate.
you can in fact easily run it with a 60fps patch even on pretty old CPUs
edit: also the 360 version ran smoother, it ran at a lower res but more consistent while the PS3 had sometimes massive drops
