- Symmetry 13y agoIf you're using integrated graphics there isn't any PCI bus involved. Even when graphics was off-die it was on the Southbridge. And the bandwidth between the GPU and the GDDR on the graphics card doesn't have anything to do with the PCI bus either, except to a small extent when synchronizing with the CPU or initially loading textures or whatever.
- rorrr2 13y agoApart from the cutting-edge APUs (like AMD Kaveri implementing hUMA), the memory of integrated GPUs and previous generation APUs was separate and copying chunks of it in between happened via the bus. Plus since we're talking about cutting-edge gaming, integrated graphics is irrelevant (and so are APUs).
