Even a single DRAM chip using 16 bits bus, will be much faster than using the PCI-e link for video memory.
You could have few MiB on chip, but DRAM chip are 256 MiB now. Beside that, having a fully internal frambuffer, could save a lot of power for pure 2D graphics. But today graphical server wait arround 32/128 MiB to do compositing. 2012/11/13 "Ing.
