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

If you mean including PS3 and X360, these two consoles had discrete GPUs. The move to AMD APUs was on the Xbox One and PS4 generation

Longer since integrated graphics used to mean integrated onto the north bridge and it's main memory controller. nForce integrated chipsets with GPUs in fact started from the machinations of the original Xbox switching to Intel from AMD at the last second.

In that case, it's more like discrete graphics with integrated CPU :)

Yeah, and vendors like Bungie are forced to cap their framerates at 30fps (Destiny 2).

They capped PC as well.

If they did, it definitely wasn't at 30. I was getting 90+ on my budget rig.

But no, I don't think they did.

Destiny 2 is capped on PC? The cutscenes are but the actual game is not

It used to have a bug that randomly cap the fps at 30. Only toggle vsync on and off again can fix it. It have no idea whether that has been fixed.
