If I am running a 32b OS I have 4GB of address space available. Assuming 3GB of system RAM and a 1GB discrete video card RAM I am using 100% of available address space.
If I have 4GB system RAM and an integrated video card, how much of the address space is used by the video card? Does it fluctuate? How can I tell within XP / Vista / Ubuntu how much memory the integrated card is using?
Also, assuming an integrated video card and a FSB the latency between video and RAM is another contributing factor to lower integrated video card performance vs discrete, right?
