Joe, Video refresh is the access to memory where the color buffer is read, and scanned out to the Ramdac. That is the calculation you correctly provided. The big user of memory bandwidth is the hardware which creates the image. This involves accesses to the color buffers, depth buffers, texture memory, etc. A unified memory system (like Timna) will use standard SDRAM. Memory bandwidth will be shared between the Video refresh, scene creation, and CPU (among other things.) Scumbria
