You are mistaken. On both PS3 and Xbox 360 CPU and GPU is on different chips and made by different vendors(CPU made by IBM and GPU by Nvidia in case of PS3 and CPU by IBM and GPU by ATI for Xbox 360). Nonetheless in PS4/XOne generation they both use single die with unified memory for everything and their GPU could be called integrated.

For the 360, from 2010 production (when they introduced the 45nm shrink), the CPU and GPU was merged into a single chip.

When they did that they had to deliberately hamstring the SOC in order to ensure it didn’t outperform the earlier models. From a consistency of experience perspective I understand why, but it makes me somewhat sad that the system never truly got the performance uplift that would have come from such a move. That said there were significant efficiency gains from that if I recall.

Yup. Prior they were absolutely different dies just on the same package
