This thought just hit me.

Will graphics cards become so fast in the near future that the PCIe bus will bottleneck the graphics card? I know SATA is the successor of IDE and PCIe is the successor of PCI but is it possible they will create a whole new bus in the future?

I mean PCI Express 3.0 (×32 link) is only 256 Gbit/s or 31.5 GB/s and my GTX 460 is 128GB/s. How does this work?

The 128GB/s is probably speed between the gpu processor & gpu ram, not related to the pcie bus speed. If bus speeds become an issue they will bring out a new faster revision or an entirely new bus design if required.

So GDDR5 has nothing to do with PCIe?

GDDR5 is the type of (graphics) RAM

No, that GDDR5 RAM is on the graphics card, so the GPU has it available without going over PCIe. The graphics card does what it needs to on itself and outputs to the display, whatever comes from the system RAM and CPU and such, or that the GPU needs to communicate to those, is easily handled by the PCIe.

To add onto what the others have said. Graphics cards barely make full use of PCI-e 2 16x. Will be a long time before we get to the constraints of PCI-e3.

PCIe is the successor of AGP for what 90% of us use it for ( Graphics cards )

We just did away with the dedicated video card port and standardized.

There is always going to be a "next" technology, it's foolish to think that what we have today, will still serve us in 10 years.
