What bus interface is the card going to have? PCI is hopelessly slow for graphics.
It depends on what you are sending over the bus. AGP was designed to rapidly access system memory so that it could be used for graphics memory. Having a lot of memory on the video board tends to negate this need. We could use 64 bit @ 66 MHz.
If you do AGP you also need AGP port support.
It depends. An AGP port can also function as a PCI port if we don't need the rapid system memory access.
PCI-express needs the PCI-express way of mapping VRAM into the CPU/GPU address spaces.
Is there a method that PCIe uses to access system memory that is different from PCI? That is, does it have some method like AGP? -- JRT _______________________________________________ Open-graphics mailing list [email protected] http://lists.duskglow.com/mailman/listinfo/open-graphics List service provided by Duskglow Consulting, LLC (www.duskglow.com)
